REQUIREMENTS FOR ELECTRICAL INSTALLATIONS

260511 - page 3 of 14

I. Backup Power: Provide backup power to existing circuits when required for phasing of the work.

The general intent of this requirement is that this work be scheduled well in advance prior to starting the work and generally is limited to non-business hours, weekends or holidays as to limit the amount of downtime of the facility, or specific Department. It is clearly understood by the

Owner there will be times during the execution of the work branch circuits maybe without power.

It is critical that temporary power be provided for those circuits that are critical to the operation of the facility; those include refrigeration, IT systems, patient areas and rooms, kitchen, heating plant etc. Work can be scheduled during other hours through the GC and temporary power will need to be made available to minimize any inconvenience to the facility.

a. Acceptable means for temporary power will need to be reviewed by the COR. If the electrical contractor can provide safe and workable solutions via back feeding from other equipment with adequate capacity within the facility and maintain safe working conditions those options may be considered by the COR. Adequate protection for cabling, overcurrent settings and related work will need to be presented clearly, concisely with safety the foremost factor. The existing generators at the facility are not intended to provide temporary power for the

Contractor in the performance of his work.

b. During construction the Contractor shall at all times maintain electrical utilities of the buildings to the maximum extent possible without interruption. Should it be necessary to interrupt any electrical service or switchboard, the contractor shall secure permission in writing from the COR for such interruption at least fourteen days in advance. Any interruption shall be made with minimum amount of inconvenience to the facility and any shut-down time shall be coordinated and such time to be included in the Contractor's bid.

c. Arrange to provide and pay for all temporary power sources (portable generators or alternate power supply from existing sources) as required by project conditions. Sizing of the emergency generator or alternate power supply (panel not affected by the work) and a layout shall be furnished for approval by the COR. Locations of temporary power sources

(generators) shall be coordinated with the COR.

d. Comply with applicable National Electrical Code and NECA 200 standard for installing temporary electric power at construction site. The temporary power required to support the facility’s electrical power requirements shall conform to the following:

1) All work shall conform to the National Electrical Code (ANSI/NFPA standard 70).

Installers shall follow the NEC, applicable OSHA standards, manufacturers' instructions, and contract documents when installing and maintaining temporary power systems.

REQUIREMENTS FOR ELECTRICAL INSTALLATIONS

260511 - page 4 of 14

2) Only qualified persons familiar with the construction and operation of temporary electrical power systems should perform the work.

3) General requirements for installing electrical products and systems are described in

NECA 1, Standard Practices for Good Workmanship in Electrical Construction (ANSI).

Other national electrical installation standards provide additional guidance for installing particular types of electrical products and systems for temporary services.

4) The temporary power needs shall be fully coordinated with the GC.

J. Temporary use of electrical equipment shall include the following:

a. Use of new installed electrical equipment to provide light and power will be permitted subject to written approval and compliance with the following provisions: Permission to use each unit or system must be given by COR in writing.

b. If the equipment is not installed and maintained in accordance with the written agreement and following provisions, the COR will withdraw permission for use of the equipment.

c. Electrical installations used by the equipment shall be completed in accordance with the drawings and specifications to prevent damage to the equipment and the electrical systems, i.e. transformers, relays, circuit breakers, fuses, conductors, motor controllers and their overload elements shall be properly sized, coordinated and adjusted. Installation of temporary electrical equipment or devices shall be in accordance with NFPA 70, National Electrical

Code, Article 590, Temporary Installations. Voltage supplied to each item of equipment shall be verified to be correct and it shall be determined that motors are not overloaded.

d. The electrical equipment shall be thoroughly cleaned before using it and again immediately before final inspection including vacuum cleaning and wiping clean interior and exterior surfaces. Prior to final inspection, the equipment or parts used which show wear and tear beyond normal, shall be replaced with identical replacements, at no additional cost to the

Owner. This paragraph shall not reduce the requirements of the electrical specifications sections. Any damage to the equipment or excessive wear due to prolonged use will be repaired replaced by the contractor at the contractor’s expense.

K. Conductor ampacities specified or shown on the drawings are based on copper conductors, with the conduit and raceways sized per NEC. Aluminum conductors are prohibited.

1.2 MINIMUM REQUIREMENTS

A. The latest International Building Code (IBC), Underwriters Laboratories, Inc. (UL), Institute of

PART 3 - EXECUTION

3.1 GENERAL

A. Install conductors in accordance with the NEC, as specified, and as shown on the drawings.

B. Install all conductors in raceway systems.

C. Splice conductors only in outlet boxes, junction boxes, pullboxes, manholes, or handholes.

D. Conductors of different systems (e.g., 120 V and 277 V) shall not be installed in the same raceway.

E. Install cable supports for all vertical feeders in accordance with the NEC. Provide split wedge type which firmly clamps each individual cable and tightens due to cable weight.

F. In panelboards, cabinets, wireways, switches, enclosures, and equipment assemblies, neatly form, train, and tie the conductors with non-metallic ties.

G. For connections to motors, transformers, and vibrating equipment, stranded conductors shall be used only from the last fixed point of connection to the motors, transformers, or vibrating equipment.

H. Use expanding foam or non-hardening duct-seal to seal conduits entering a building, after installation of conductors.

I. Conductor and Cable Pulling:

1. Provide installation equipment that will prevent the cutting or abrasion of insulation during pulling. Use lubricants approved for the cable.

2. Use nonmetallic pull ropes.

3. Attach pull ropes by means of either woven basket grips or pulling eyes attached directly to the conductors.

4. All conductors in a single conduit shall be pulled simultaneously.

5. Do not exceed manufacturer’s recommended maximum pulling tensions and sidewall pressure values.

LOW VOLTAGE ELECTRICAL POWER CONDUCTORS AND CABLES

260519 - page 6 of 6 junction boxes, and pullboxes. Apply the last two laps of tape with no tension to prevent possible unwinding. Where cable markings are covered by tape, apply tags to cable, stating size and insulation type.
