PART 1 – GENERAL

1.1 PROJECT OVERVIEW

This specification specifies project details for installation of an owner-provided sports lighting system. This lighting system consists of a contactor cabinet for controls, fixtures, pre-wired crossarms with mounting equipment, remote electrical components enclosures with mounting equipment, and a pre-wired pole harness.

It shall be the responsibility of the installing contractor to install the lighting system based on Manufacturer-provided installation instructions and NEC or any local electrical codes.

The lighting system is designed to reuse the existing pole structure, along with the existing underground wire from the distribution panel to each pole. The installing contractor will be responsible for any electrical work required by the authority having jurisdiction at the distribution panel (ex. State of Michigan plan review document submission, resizing of breakers/fuses to accommodate new loads, etc.) to install the owner-provided lighting contactor cabinet.

1.2 ELECTRICAL SYSTEM REQUIREMENTS

A. Contractor Responsibility: The installing contractor shall be responsible for providing the equipment and installation of a complete and operational system commencing from the secondary side of the service transformer and terminating at the safety disconnect within the electrical enclosure, 10’ above grade, on each lighting pole. The electrical contractor shall coordinate any necessary transformer and switchgear locations, as well as identifying the voltage and phase of the service, with the local power company and the Owner’s representative before any equipment is installed.

B. Electric Power Requirements for the Sports Lighting Equipment:

Electric power: 240 Volt, Single Phase, to be confirmed by installing contractor.

C. Maximum total voltage drop: Voltage drop to the disconnect switch located on the poles shall not exceed three (3) percent of the rated voltage.

D. System Design

1. The electrical system equipment shall consist of:

a. The distribution panel board to be reused.

b. Owner-provided lighting contactor cabinet.

c. Conductors and conduit for the feeder circuit from the distribution panel board to each pole’s disconnect shall be reused.

d. Grounding conductors and grounding methods for the following:

(1) The main service entrance panel board. (per NEC or local codes)

(2) The lighting contactor enclosure. (per NEC or local codes)

(3) Each electrical component enclosure mounted on the lighting poles. (Equipment Grounding System) (per NEC or local codes)

(4) Lightning Protection for individual poles as follows (per NFPA 780):

For existing poles, all structures shall be equipped with lightning protection meeting NFPA 780 standards.

2. Any new wiring shall be all copper wire and shall be installed meeting the NEC and local electrical codes. Acceptable copper wire types need to comply with any local requirements, but will be labeled either THHN or THWN. Conduit elbows located at the electrical panel shall be rigid galvanized steel.

E. Design Standards

1. All circuits shall be designed so that the voltage at the safety disconnect in the electrical enclosure near the base of each pole is within 3% of nominal.

2. All work shall meet local and National Electrical Codes. It shall be the installing contractors’ responsibility to correct any work deemed unacceptable by local electrical inspectors.

3. All electrical components shall be UL Listed for the appropriate application.

4. Each pole shall be on a dedicated circuit. If common poles are used, or a pole is to have fixtures on separate circuits, multiple dedicated circuits shall be run to that pole. Consult lighting equipment specifications and lighting manufacturer for special circuitry information.

F. Submittal Information

The successful contractor shall provide an electrical plan/schematic, detailing all of the equipment described above, to the owner prior to commencing work. This electrical plan/schematic shall bear the stamp of an Electrical Engineer with P.E. status within the State of Michigan.

Sling enclosure stack under the welded arm for strapping connections (not under the BallTracker® luminaire crossarm) and lift enclosure stack.

Using the enclosure stack ID located on top of the enclosures, determine orientation of assembly. An orientation of "0" indicates the enclosures face the field. Position bottom enclosure hub at 10 ft (3m) above grade.

BallTracker® luminaires should face the field.

Luminaire Attachment

Overview The luminaire assembly conveniently allows mounting of luminaires on the pole as a unit. Luminaires are factory built and shipped in individual cartons. Luminaires are factory aimed and ready for installation to poletop luminaire assembly. Do not disassemble.

Tools/Materials Needed

Note: Leave luminaires in box until ready to assemble.

Keep protective cover on luminaire until ready to attach to crossarm. Do not leave luminaires unassembled from crossarm in wet conditions.

Assembly Procedure Verify pole ID on luminaire cartons matches pole and location on Field Aiming Diagram.

Remove and discard orange protective caps from luminaire knuckle and mounting plate that cover electrical connections. Do not remove orange tag around captive bolts.

Note: The luminaire style may vary from what is shown.

�Warning Luminaire may fall if bolts are not tight.

Do not remove tag before tightening bolts.

Attach luminaire retaining cable (if present). Route luminaire cable through crossarm anchor point, through luminaire block, and back through the block under the set screw. Luminaire attachment point will vary per luminaire design.

Using 7/16 in socket and torque wrench, tighten cable set screw to 60 in•lb (6.8 N•m).

Poletop Luminaire Assembly

Overview All luminaires are factory aimed to their exact position on the field. To ensure proper poletop luminaire assembly alignment, a simple-to-use alignment beam completes the precision field aiming. The alignment beam is attached in the factory to one poletop luminaire assembly on each pole.

Tools/Materials Needed

Contractor Supplied ❏ 15/16 in open-end torque wrench or torque wrench with 15/16 in crows-foot

❏ 15/16 in open-end wrench

❏ Chalk or flags to mark aiming points on field

❏ Measuring tape

Installation Procedure Plot and mark aiming point(s) on field. Refer to Field Aiming Diagram.

If assembling pole on ground, ensure all pole clamping hardware is torqued to 80 ft•lb (108 N•m) using 15/16 in open-end torque wrench before lifting pole (see step 5). Instead of turning luminaire assembly, turn pole to align with aiming point. Do not remove plastic wrap from luminaires until ready to lift the pole.

Person B

Aiming point

Person A

Aim luminaire assembly using alignment beam. Device projects a narrow vertical beam of light that is only visible when you are aligned with it. This step requires two people.

Person A: Stand on field aiming point and look at pole alignment device. It is attached to a luminaire. Walk parallel to crossarms until you see beam. Signal person B to rotate luminaire assembly left or right until beam aligns with aiming point. Beam may be visible, however when pole is aligned, you will see a bright flash as you stand directly on aiming point.

Person B: Following direction from person A, rotate luminaire assembly left or right until it is aligned.

Warning Falling material hazard If erecting pole with luminaire assembly attached, do not attach rigging to luminaire assembly. Follow pole supplier instructions for lifting.

Warning Laser radiation hazard Pole alignment beam is safe for viewing at a distance of three feet (one meter) or more. Do not look into beam from closer than three feet (one meter). Do not use binoculars, camera, or telescope to view beam from any distance. Locator beam is a class 2M laser device. Wavelength: 635-660 nm, Laser power for classification: <1 mW continuous, divergence:

<1.5 mrad x 1 rad. Using alignment beam in a manner other than as described here may result in hazardous exposure.

Do not modify, dismantle, or attempt to repair.

If assembling multiple poletop luminaire assemblies at same orientation ensure crossarms are aligned with crossarms above and below.

If assembling back-to-back poletop luminaire assemblies ensure crossarms are parallel.

Ensure back-to-back crossarms remain parallel while tightening.

After all hardware is torqued and poletop luminaire assembly is secure, release rigging.

Note: Pole clamping hardware configuration varies with pole diameter and shape.
