Multi Conductor Cable Ampacity Chart

Usually a general purpose house circuit is designed for 20.

Multi conductor cable ampacity chart.

Nm b is permitted to be manufactured with conductors as large as 2 awg but multiconductor uf b is limited to conductors no larger than 6 awg by the ul standard. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. We also stock alpha wire and belden wire and cable products. Current is measured in amperes or amps.

Amp chart lead wire current carrying capacity ampacity awg size insulated conductor temperature rating awg size at 80 c at 90 c at 105 c at 125 c at 150 c at 200 c 40 0 33 0 49 0 55 0 60 0 71 0 78 40 38 0 47 0 68 0 77. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. The environment surrounding a wiring method can affect the ampacity of the conductors. Ampacities based on 90 c and 30 c ambient temperature per table 400 5 b of the national electric code.

Based on nec table 310 60 c 74 ampacities of an insulated. Home products our products lie in the walls of your home in the transmission lines that power our neighborhoods in the places we work schools where we learn and the hospitals that keep us well. Nec table 310 15 b 16 ampacities are based on an ambient temperature of. 1 for cables with a service temperature of max.
