659/NEMA WC 71 and UL 1072.

2. Qualification Flame Tests:

a. Cable must pass the UL 1072 vertical tray flame test.

b. Cable must meet the vertical tray flame test requirements of IEEE

383 and IEEE 1202.

3. Production Tests: Perform in accordance with applicable engineering

standards or manufacturer's standards, whichever are more stringent.

PART 3 EXECUTION

3.01 WIRE AND CABLE INSTALLATION

A. Wire and Cable: Must comply with the requirements of Sub-section 12-4.02,

Common Work Results for Systems Conductors.

3.02 SPLICE AND TERMINATION INSTALLATION

A. Use continuous lengths of wire and cable between power source and

equipment. Splices may not be used without written authorization of the

Engineer.

B. Where splices are required by conditions and authorized by Engineer, make

them only in approved outlet, junction or pull boxes, in vaults, or in equipment

cabinets, in accordance with cable and terminator manufacturers instructions.

C. Connect conductors No. 8 AWG or larger to apparatus, bus work, switch or

fuse blocks by means of compression type lugs, unless otherwise indicated.Permanently bolt lugs to give maximum contact surface.

D. 2.4 kV splice assemblies:

1. Preferred type assemblies must be neatly taped after assembly.

2. Alternate type assemblies must be installed per the manufacturers

instructions.

3. Where splices are detailed on Contract Drawings, install as shown and

as directed by Engineer.

E. Tools:

1. Use tool as recommended by the terminal manufacturer.

2. Smaller than No. 2 AWG: Apply with mechanical ratcheting type or

electric/hydraulic type compression tool.

3. No. 2 AWG and larger: Apply with electric/hydraulic type compression

tool.

3.03 FIELD QUALITY CONTROL

A. Dc Feeder Cables:

1. High Potential Test: Perform test at voltages and for time durations in

accordance with ICEA and NETA recommendations.

2. Test positive feeder and negative return cables separately.

3. Test is passed if there is no insulation breakdown or excessive leakage

current.

4. If a failure is detected, locate and determine the trouble, replace the

defective cables, make necessary corrections, and retest the cables at

no additional cost RT.
