What size wire for 125 amp 3 phase service. Recommended wire sizes switches and fuses for 3 phase 60hz capacitors these wire sizes are based on 135 of rated current in accordance with the national electrical code article 460 240 volts 480 volts 600 volts kvar current amps wire size 90 c type thhn xhhw or equiv fuse amps c b. For motors it is recommended to multiply the nameplate fla by 1 25 for wire sizing. I want to know if the lra 117 amp divide by 3 or mult by 3.

500mcm copperwire with an insulation factor of 75 and 90 degrees c is rated at380 and 395 amps respectively. All wiring will be copper two 2 thhn for hot one 3 thhn for neutral and one 4thhn for the ground. 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.

Wire circular mils 3 x 2 x ρ x i x l allowable voltage drop of source voltage. Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v. I m looking for suggestions on wire size this is what was given to me by a friend of mine.

The run will be about 100 feet and the breaker boxes are 125 amp. V1 v2 load in amps calculate. For a motor lra 117 amp 230 volt three phase how many amps for safety box and the contactor.

The wire size according to codehas to be up sized to 125. Or switch amps current amps wire size. Enter different values in the boxes below and click on send you can use the tab button to move between boxes.
