3.0 GENERAL INFORMATION

3.1 Availability & Character of Service

The information contained in this Guide refers predominately to service requirements at the usual voltages for residential and general service installations. Service installations greater than 600 volts are not covered in this Guide. The customer should contact the Company with questions regarding service at voltages greater than 600 volts. The Company's rules, regulations, and tariffs, as filed with the MD PSC, shall apply to the installation and use of the service furnished.

The customer shall consult the Company to determine whether the desired service is available in the particular location. This request should be made well in advance of the date actual service connection is required. If service is available, determine its exact character; that is, the voltage single-phase or three-phase, since these characteristics may vary in different locations. These characteristics are especially important for the proper operation of motors and other major equipment. Normally, this information will be provided in writing from authorized Company personnel to avoid possible misunderstanding. The available voltages are as follows:

Phases Configuration Voltage (V)

Single-Phase 3-wire 3-wire

120/240 V 120/208 V

Three-Phase 4-wire Delta 4-wire Wye 4-wire Wye

240/120 V * 208Y/120 V 480Y/277 V

*This service voltage is not available for underground service energized from an underground primary source regardless of the source voltage. This service is available from an overhead closed-delta or open-delta transformer bank energized from an overhead 12.5 kV and below primary source. Also, this service is available from an open-delta transformer bank with a maximum transformer capacity of 1-75 kVA and 1- 25 kVA energized from an overhead 34.5 kV primary source. Overhead closed-delta transformer banks are not permitted on a 34.5 kV primary source.

The Company may, if requested, advise and assist existing or prospective customers in the selection of electrical equipment, facilities, capacitors, protective coordination, or with information concerning rates.

3.2 Application for Service

The customer shall make applications for each class of service for new, upgraded, or relocated, permanent or temporary service or when the customer identity changes. Before service is supplied by the Company, the customer shall complete the application process. Application may be submitted via the telephone, fax, or the Internet to a Company business office, and should be submitted well in advance of the date actual service is required. The appropriate telephone and fax numbers and Internet address are listed below:

Maryland Company Telephone Number Fax Number Potomac Edison 800-686-0011 877-289-3674

A copy of the Fax Application Builder Install Request Form 1046 can be found in Appendix 1.

Application for electric service can found online at www.firstenergycorp.com/builders-contractors. Then click on Establish or Upgrade Service form under the heading Online Contractor Form for New or Upgrade Service.

After the necessary customer information is received and all customer requirements are met, the typical minimum lead-time to complete Company work is as follows:

SOW Attachment G http://www.firstenergycorp.com/builders-contractors http://www.firstenergycorp.com/builders-contractors https://www.firstenergycorp.com/service_requests/Builders_Contractors/Request_New_Upgrade_Service.html https://www.firstenergycorp.com/service_requests/Builders_Contractors/Request_New_Upgrade_Service.html

Type of Extension Lead-time Residential Service Drop / Lateral 4 weeks Residential Line Extension 8 weeks Commercial/Industrial Drop / Lateral 6 weeks Commercial/Industrial Line Extension 16 weeks Residential/Commercial/Industrial Development 16 weeks

These recommendations should allow service to be established as near to the desired time as practicable. Your Company representative will provide additional information on service particulars, work scope, and timelines.

The following information is required from the customer. The Company cannot begin work until the necessary information is provided:

1. Service address (including nearest intersecting roads),

2. Lot number (and block number where applicable) and subdivision name,

3. County/Tax District name,

4. Contact persons (developer/architect, electrical contractor, etc.) names, addresses, mailing addresses, and their telephone/fax numbers,

5. Owner name, address, mailing address, and telephone/fax numbers,

6. Person to be billed (including their Tax ID or Social Security Number) and the mailing address,

7. Type of electric service required – overhead (OH) or underground (UG),

8. Service voltage desired (e.g., 120/240 V single-phase, 208Y/120 V three-phase, or 480Y/277

V three-phase),

9. Amp rating of the main disconnecting means,

10. If Residential: Determine heating fuel (oil, gas, electric, etc.), water heater fuel, electric range, air conditioning (size, if yes), total square feet, preferred electric meter location, and number of services. Also, determine if any other large or special electric loads (e.g., welder or kiln) will be used.

11. If General Service (Commercial/Industrial): Electric one-line, load information (nameplate data) for all single-phase motors larger than five hp, three-phase motors larger than ten hp, tons of air conditioning, kW process heat, kW lighting, kW computers, presses, welders, x-ray machines, and other equipment having an in-rush current or other potentially disturbing characteristic, as well as other unusual loads.

12. For Developments: An approved plot plan drawn to scale showing crossroads, proposed structures, wells, septic, decks, drives/parking areas, pools, ponds, preferred service route, planned major landscape changes and future development areas, and any other known or proposed obstructions that may interfere with the Company supplying electric service.

Electrical loading information will be required for the design. The customer/developer shall provide an executed Company standard blanket utility easement for their developments prior to individual lots being sold or the installation of any Company electrical facilities.

13. Date that the electric service is wanted.

14. For interconnected generation (solar, wind, etc.) see Section 8.6.

The customer/developer shall provide the Company with a copy of the customer plot plan showing the locations of buildings, lot numbers, property lines, streets, parking lots (if applicable), easements, underground facilities, obstructions, or utilities (if known), as well as proposed electric service entrances and metering locations. The customer/developer shall stake the locations of all proposed buildings, the lot lines, and driveways so that the Company can decide where to install its facilities.

The Company may refuse to provide electric service, consistent with Maryland law and Company tariffs.

3.3 Line Extensions

To avoid delay, customers desiring service beyond the existing electric distribution lines of the Company are advised to inquire of the Company the conditions under which service will be extended and make the necessary arrangements before wiring installations are commenced.

Depending on the situation and the nature of the facilities desired or required, the customer may be responsible for some of the preparation and clearing of the property to clear trees and vegetation or provide access to Company vehicles and personnel, rights-of-way acquisition, easements, permits, construction costs, and, for underground extensions, trenching and backfilling. Note: difficulties in obtaining private rights-of-way and governmental permits (e.g., FAA, Army Corp of Engineers, or EPA permits) may result in significant delays to the construction.

Cost contributions are defined in the applicable Company’s Tariff. The Company can provide the terms and conditions of extending its facilities to supply service upon request.

The requirements for a residential structure to be considered a permanent installation:

Masonry or Wood Structure (“stick built” or Modular) Type Home:

• Directly connected to a public water system, water well, or other reasonable source of potable water meeting all applicable local requirements,

• Directly connected to an approved septic system, a public sewage system, or an alternate sewage method meeting all applicable local requirements,

• Containing a living area, kitchen, and bathroom,

• Located on a permanent foundation.

Mobile or Manufactured Home:

• Directly connected to a public water system, water well, or other reasonable source of potable water meeting all applicable local requirements,

• Directly connected to an approved septic system, a public sewage system, or an alternate sewage method meeting all applicable local requirements,

• Wheels and axles removed,

• Underpinnings or some type of permanent connection (anchoring).

Vehicle-type units primarily intended as temporary living quarters, to include, but not limited to, recreational vehicles (“RV’s”), motor homes, travel trailers, truck campers, park trailers and camping trailers shall not be considered as permanent. Mobile or manufactured homes for the purpose other than as a dwelling unit (i.e. on-site offices, mobile dressing rooms, banks, clinics, stores, or mobile displays) shall not be considered as permanent.

3.4 Number of Services & Meters

The Company will connect only one set of service conductors to each separate dwelling (single or part of a multiple unit), apartment, farm, commercial or industrial establishment as one customer through one meter or one unified set of meters. Therefore, customers will typically be served at one voltage at either single-phase or three-phase, but not both. If occupied by several customers, each customer may have one meter for each class of service rendered. All customer installations shall conform to the NEC and local codes. Parallel runs of service cable extending from Company-owned equipment to multi-position meter centers should be avoided and require prior Company approval.

Upon request and if the Company approved, a second service may be permitted based on the exceptions listed in NEC Article 230.2. A permanent plaque or directory shall be installed at each service drop or lateral, or at each service equipment location. It shall denote all other services on or in that building or structure, and the area served by each.

3.5 Use of Service by Customer

Customer-owned wiring and electrical equipment shall be sufficiently sized (per NEC) and listed for its intended application.

The customer’s wiring and equipment including the self-contained meter socket shall be installed and maintained by the customer, at the customer’s expense, and in the condition required by the insurance providers, governmental authorities having jurisdiction, and Company requirements.

It is necessary for the protection of the customer that all work, wiring, and apparatus be installed and maintained by a qualified electrician. A qualified electrician is one who has the skills and knowledge related to the construction and operation of the electrical equipment, systems, and installations and has received safety training to recognize and avoid the hazards involved.

The Company’s facilities, which are used to provide service, have limited capacity and may be damaged if overloaded. Therefore, the customer shall notify the Company prior to increasing their energy usage or altering their service equipment so that Company facilities of proper capacity may be provided. Failure to properly notify the Company of such additional requirements may result in an extended outage or in damage to the customer’s and/or Company’s equipment. The customer shall be responsible for all expenses and/or damages to the customer’s and/or Company’s facilities resulting from failure to give proper notification. The customer may also be subject to charges by the Company for work required to meet the customer’s alterations. The customer should contact the Company for information concerning charges for such work.

The service shall not be used in any manner that disturbs or impairs the operation of the Company's system or that will interfere with service to other customers. If such interference does occur, due to the use of apparatus installed upon a customer's premises, such customer shall either discontinue the use of such apparatus or make the necessary revisions to the apparatus, including additional equipment that may be required to alleviate such conditions, or the Company shall have the right to discontinue the offending service.

For proper service, the wiring on all single- or three-phase installations shall be arranged so that the load, to the extent possible, is balanced among each phase-wire. For three-phase services, the load imbalance between phases shall not be greater than 15 percent of the customer’s peak load.

3.6 Interruption & Liability*

The Company will use reasonable diligence in providing regular and uninterrupted Service, but the Company shall not be liable for any loss, cost damage or expense to any Customer occasioned by failure to supply electricity according to the terms of the contract, or by any interruption or reversal of the supply of electricity, if such failure, interruption or reversal shall be due to the elements, public enemies, strikes, or order of Court, which are beyond control of the Company, or any cause except willful default or neglect on its part.

The Company may, without liability therefore, interrupt or limit Service to any or all Customers whenever in the sole judgment of the Company such action is indicated in order to prevent or limit any actual or threatened instability or disturbance on the electric system of the Company or any electric system interconnected with the Company.

3.7 Final Connections

Residential/Commercial - All final connections for temporary or permanent service, between the Company's facilities and the customer's wiring, shall be made by the Company. Refer to Exhibit 1 to determine party responsible for supplying connectors.

* To the extent this provision contradicts any terms in the Company’s current applicable tariff, the tariff provision shall govern.

The Company shall assume no responsibility for changing the location of its service drop attachments if an improper location is chosen without consultation with the Company, or if the mutually acceptable location is not utilized.

If it becomes necessary for the Company to change the location of its facilities or the character of the electrical service to comply with the requirements of governmental agencies, codes, or other causes beyond the Company’s control, the customer shall, at the customer’s expense, change its facilities (e.g., customer’s wiring, service entrance, and utilization equipment) to accommodate the Company changes.

Service entrance equipment interrupting capacity shall meet or exceed the maximum available fault current. The customer should contact the Company to determine the estimated available fault current and subsequently determine the minimum required equipment rating.

3.8 Grounding/Bonding

The customer shall install the service entrance so that all of the grounding/bonding requirements of the NEC are met or exceeded. The customer’s service entrance shall have a minimum of two driven ground rods (8 feet minimum length) at least six (6) feet apart. The grounding electrode conductor shall be continuous from the service entrance main disconnect to both driven ground rods. Refer to Exhibit 5.

3.9 Inspection

In addition to complying with the NEC, the service shall be in accordance with the requirements of the Company and such state and local inspection requirements as may be in force at the time such installation is made.

Before a new, temporary, upgraded, modified, or repaired service to a customer service location is energized, the Company should verify that the installation of the customer’s meter socket and associated equipment has been inspected and approved by the local or state electrical inspection authority.

When the Company deems that a potentially hazardous condition exists, it may refuse to energize the customer’s service until the customer remedies any deficiencies.

Service Restoration - Fire or Flood: If the meter or service entrance equipment has been subjected to fire or flood conditions, an inspection from the above referenced authority, and a release, when applicable, from a Fire Marshall or equivalent is required before service will be restored.

Service Restoration – Disconnected Services: If a service has been disconnected (i.e., service wires cut or meter blocked/removed) for twelve (12) months or more, a new inspection by the local or state inspection authority is required before the service will be reconnected.

3.10 Meter & Seal Tampering

Tampering means to interfere with, damage, or by-pass a utility meter, conductor, or attachment with the intent to impede the correct registration of a meter or the proper functions of a conductor or attachment so far as to reduce the amount of utility service that is registered by the meter.

Tampering includes the unauthorized reconnection of a utility meter, conductor, or attachment that has been disconnected by the utility.

In the event of tampering, or theft of service by the customer, consumer, or other person, the Company will comply with the provisions of Maryland law and Company tariffs. Services that have been disconnected due to tampering may require an electrical inspection before reconnection.

Breaking of meter seals and/or removal of meters by customers, electrical contractors, or other unauthorized personnel, without prior Company permission, is prohibited and may be subject to penalties.

3.11 Meter Attachments

No attachments by the customer or the customer’s agent are permitted to Company-owned meters, meter circuits, or ancillary meter devices.

The Company will supply, upon request by a customer, kWh and/or kvarh pulses from a Company-owned meter for demand control purposes. The Company will assess a cost to the customer in accordance with specific Company charges for this connection.

3.12 Disconnect/Reconnect of Existing Service (Upgrades/Maintenance)

The first step to be taken when upgrading or performing maintenance on an existing service is to contact the Company’s Customer Contact Center for guidance and applicable fees. Customers, electricians, or contractors are not permitted to disconnect/reconnect overhead service drops or underground service laterals. All overhead and underground electrical upgrades shall be inspected prior to reconnection (refer to Section 3.9).

The Company reserves the right to update meter and service locations at the time of upgrade for the purposes of applying current clearance requirements and meter location guidelines. Service equipment installed without approval or incorrectly located shall be subject to change or relocation.

3.13 Locating Underground Electric Facilities

State laws require that an excavator notify the One-Call System in advance of digging. Trained personnel will locate and mark electrical underground facilities.

To simplify the "Call before You Dig" calling process, 8-1-1 has been designated by the FCC as a nationwide telephone number. In Maryland, the 8-1-1 number will transfer a caller to the appropriate state One-Call system. You may also contact the appropriate One-Call agency online at www.call811.com/state-specific.aspx.

For projects in Maryland - call Miss Utility Maryland at least two (2) full working days, not counting the day of the call, but not more than ten (10) working days, excluding weekends and legal holidays, before digging at 811 or (800) 257-7777 to request that a location be marked. The Center is open 24 hours/day and 365 days/year. For more information, or to enter requests for locate tickets online, visit www.missutility.net/maryland.

3.14 Required Clearance from Markout for Digging in the Vicinity of Company Underground Electric Facilities

After the underground facilities have been located (refer to Section 3.13), hand digging is required within a tolerance zone, which is 18 inches from all sides of the markout stake, flag, or hash mark and the closest edge of any parallel trench dug by another party adjacent to the Company’s underground facilities.

3.15 Buildings/Structures & Swimming Pools/Spas/Hot Tubs near Electric Lines

Buildings and structures (including signs, flagpoles, light standards, antennas, or aerials) shall not be installed under, over or in such proximity to electric lines that they could be raised into or fall onto such lines or that they cannot be safely maintained. Antennas, aerials, or any device shall not be attached to a Company pole or any pole supplying electric service to the customer without specific Company authorization. NESC/NEC clearances shall be maintained. The customer should consult the Company for specific clearance requirements and possible easement restrictions.

The Company does not recommend placing a swimming pool, spa, or hot tub under its existing service drop or other electrical conductors. Specifically, a swimming pool shall not be located within a minimum of twenty-five (25) feet of the Company’s overhead conductors, measured horizontally from the edge of the pool, without written approval from the Company. The clearance http://www.call811.com/state-specific.aspx between the Company’s underground cables (primary and secondary) and the edge of the pool or its auxiliary equipment shall not be less than five (5) feet (measured horizontally).

3.16 Attachments on Company-Owned Facilities

Under no conditions shall the customer’s facilities or other equipment such as signs, posters, banners, or notices be installed on the Company’s poles or other property unless special arrangements have been made with the Company. The customer shall contact the Company for details. The Company does not permit painting of Company-owned equipment by the customer.

3.17 Clearance of Trees from Power Lines

Trees & Transmission Rights-of-Way

• ATSI, TrAILCo, and the Company's long distance, high voltage transmission lines provide power to thousands of our customers and are vital reliability links with other utilities across the country. Keeping our transmission rights-of-way free of unwanted trees and other vegetation is very important to providing reliable and safe electric service.

• All vegetation on or adjacent to the right-of-way shall be low-growing, compatible species.

Additional information on correct tree selection can be found at www.first energycorp.com/trees. Click on “Maintaining Transmission Rights-of-Way” on left side of page.

Trees & Distribution Lines

• Tree related incidents are a major cause of electrical outages. Therefore, care must be exercised when planting trees to make certain that they will not interfere with distribution power lines, even when the trees reach full, mature growth. Trees that grow more than 25-feet tall should not be planted within 20 feet of distribution power lines.
