c. Recommended maximum pulling tension and minimum bending radius of wire and
cable.
d. Recommended wire and cable pulling lubricants.
e. All field test data.
2.01 WIRE AND CABLES:
A. General: Provide wire and cable suitable for the location where installed.
B. Conductors: Minimum conductor size shall be #12 AWG. Except #14 AWG stranded can be
used for controls unless indicated or specified otherwise. Provide solid conductors for power
and lighting circuits No. 10 AWG and smaller unless indicated or specified otherwise. Provide
stranded conductors for sizes No. 8 AWG and larger unless indicated or specified otherwise.
C. Conductor Material: Use copper for all sizes.
D. Provide wire and cable numbers that match electrical schematics.
E. Provide stranded hookup wire with appropriate voltage rating and ampere rating inside of all
control enclosures.
2.02 CONNECTORS FOR CONDUCTORS:
A. Provide UL-listed factory-fabricated, solderless metal connectors of sizes, ampacity ratings,
materials, types and classes for applications and for services indicated. Use connectors with
temperature ratings to or greater than those of the wires upon which used. Connectors shall be
identified for the conductor material.
1. Lighting and receptacle circuit connectors for No. 10 AWG and smaller shall be twist-on
spring solderless connectors. Provide silicone filled twist-on watertight/raintight
connectors for all lighting circuits and receptacles circuits routed outdoors or indoors in
wet locations.
2. Nonlighting and nonreceptacle circuit connectors for No. 12, No. 10 AWG, and
connectors for No. 8 AWG and larger shall be solderless connectors.
3. All uninsulated joints shall be taped to provide an insulation value equal to that of the
wire.
PART 3 - EXECUTION
