Cut to length sold by the foot. It can be used for direct burial or in ducts. 240 4 e through g the overcurrent protection shall not exceed 15 amperes for 14 awg 20 amperes for 12 awg and 30 amperes for 10 awg copper.

Factors tor ambient temperature and number of conductors have been applied. Enter the desired footage in the qty box. Aluminum or copper clad aluminum. Stranded wire construction is favored instead.

The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. Minimum 1 to maximum 1000. The tables below are intended to be a general guide for wire size and amp ratings. Allowable ampacities of insulated copper conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient temperature of 30 c 86 f.

Turns of wire no insulation. Usually a general purpose house circuit is designed for 20. 43 58 79 90 105 121 145 166 189 223 245 281 305 328 378 413 452 466 479 500 542. Current is measured in amperes or amps.

The following table of wire sizes does not show any sizes bigger than 4 0 gauge because solid copper wire becomes impractical to handle at those sizes. 1 the load current rating and the overcurrent protection for conductor types shall not exceed 15 amperes for 14 awg 20 amperes for 12 awg and 30 amperes for 10 awg aluminum and copper clad aluminum after any correction factors for ambient temperature and number of conductors have been applied.
