125 Amp Wire Size

Enter your proposed cable size type of insulation voltage ambient temp 30 is norm your cable length and circuit load in amps.

125 amp wire size. The wire size chart below shows allowable ampacities of insulated 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 air temperature of 30 c 86 f. The wire size according to code has to be up sized to 125. The wire size for 125 amp service should be a 10 gauge bare ground wire.

Amperes enter the maximum current in amps that will flow through the circuit. V1 v2 load in amps calculate cable selection copper only up to 25mm above this cable reactance must be considered. 291 67 x 125 364 6.

The figure we would plug into the calculator would be. From table 430 150 they draw 40 amps 14 amps and 3 amps respectively. For motors it is recommended to multiply the nameplate fla by 1 25 for wire sizing.

500mcm copper wire with an insulation factor of 75 and 90 degrees c is rated at 380 and 395 amps respectively. Voltage enter the voltage at the source of the circuit. The wire size according to code has to be up sized to 125.

40 x 1 25 14 3 50 14 3 67 amps. 291 67 x 125 364 6. Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v.
