LOW-VOLTAGE ELECTRICAL POWER CONDUCTORS AND CABLES 260519.00 - 1

SECTION 260519 - LOW-VOLTAGE ELECTRICAL POWER CONDUCTORS/CABLES

PART 1 - GENERAL

1.1 SCOPE:

A. This section outlines the quality and type of conductors to be used in the various systems, locations, and conditions.

PART 2 - PRODUCTS

2.1 WIRE AND CABLE 600 VOLT:

A. GENERAL:

1. Conductors shall have current carrying capacities as per NEC and with 600-volt insulation, #12 AWG average minimum for 20-amp circuits except for controls, and fixture wire.

Conductors shall be copper./GENERAL USE:

1. #12 and #10 shall be solid, type THWN/THHN insulation.

C. FEEDERS AND GENERAL USE:

1. #8 awg and larger, and any size to motors shall be stranded type THWN.

D. FIXTURE WIRE:

1. Fixture wire shall be type THHN may be used in the channel of and flex to all fixtures. Wire size shall be #12 AWG for all fixtures. Fixture wire shall extend only from the fixture to the first junction box and not over 6' in length.

E. CONTROL WIRE:

1. Control wire shall be minimum #12 AWG copper, type THHN-THWN. Full color range as indicated for individual systems. See other sections of the specifications for requirements.

F. MANUFACTURER:

1. Wire and cable shall be as manufactured by Southwire Corporation or approved equal.

G. WIRE CONNECTIONS:

1. On wire larger than #10 shall be made with approved solderless connectors and covered with Scotch #33 electrical tape so that insulation is Owner approved equal to conductor insulation.

2. All connections and splices in exterior, handholes, pull/junction boxes, and underground locations shall be made completely watertight and waterproof.

H. #10 AND SMALLER COPPER CONNECTIONS:

LOW-VOLTAGE ELECTRICAL POWER CONDUCTORS AND CABLES 260519.00 - 2

1. Shall be made with T & B Sta-Kon wire joints, PT series, complete with insulating caps and installed with WT161 Tool or WT2000 Tool, Ideal Super-Nuts (not wire nuts), Ideal Wing Nuts, or Buchanan Elec. Products B Cap or Series 2000 Pres-Sure connectors complete with nylon snap-on insulators and installed with C24 pressure tool.

PART 3 - EXECUTION

3.1 INSTALLATION OF WIRE AND CABLE:

A. No conductor shall be smaller than #12 except where so designated on the drawings or hereinafter specified.

B. All conductors, wire, and cable shall be installed in conduit unless otherwise noted.

C. Multi-wire lighting branches shall be used as indicated.

D. All joints and splices in wire shall be made with approved solderless connectors and covered so that insulation is Owner approved equal to conductor insulation. Splices shall not be permitted in control, security, fire alarm, television, or communications systems, or where otherwise noted.

Splicing of wire or cables will not be allowed below grade, including within boxes below grade.

E. No splices shall be pulled or installed into conduit.

F. Both conductors and conduits shall be continuous from outlet to outlet.

G. No conductor shall be pulled until conduit is cleaned of all foreign matter.

H. In installing the main electrical service, additional slack conductors shall be provided and terminated as required by electric utility for connection to utility equipment. Field coordinate with the power utility company prior to installing conductors. Contractor shall provide all secondary connections to utility company transformer per utility company requirements. Provide all lugs, spade conductors, etc., per drawing and utility company requirements.

I. In installing parallel conductors, it is mandatory that all conductors making up the feeder be exactly the same length, the same size, and the same type of conductor with the same insulation. Further, each group of conductors making up a phase or neutral must be bonded at both ends in an approved manner.

J. Conductor sizes indicated on circuit homeruns or in panelboard schedules shall be installed over the entire length of the circuit unless noted otherwise on the drawings.

K. Conductors shall be continuous and unspliced where installed in conduit. Splices shall occur only within wiring troughs, wireways, junction boxes, outlet boxes, or equipment enclosures where sufficient additional room is provided for all splices.

L. Provide isolated ground conductors per drawing requirements.

3.2 CIRCUITS AND BRANCH CIRCUITS:

A. Outlets shall be connected to branch circuits as indicated on drawings. No more outlets than are

indicated shall be connected to a circuit.

3.3 WIRE AND CABLE DESIGNATION AND COLOR CODING:

A. Non-ferrous identifying tags or pressure sensitive labels shall be securely fastened to all cables, feeders, and power circuits in panels, starters, terminations of cables, etc. Tags or labels shall be stamped or printed to correspond with markings on drawings so that feeder or cable number and phase can be readily identified.

B. Each branch circuit and feeder conductor shall be color coded. For all conductor sizes the entire insulation shall be of the color as indicated below. Color code shall be strictly adhered to. Phase tape is not permitted.

120/208 Volts Phase Color

A Black B Red C Blue

Neutral White Ground Green

277/480 Volts

Phase Color
