125 Amp Wire Size Chart

125 Amp Wire Size Chart - Its a 90' run in underground electrical epvc. You size the wire to actual load. I know minimum size would be 1/0 al for the phases. Sorry about the other post. 125 amps, minimum al conductor size is #1/0. Does it state that se cable must have all the same wire sizes. I'm running #3 thhn for a 125 amp pool sub panel. For the 2 hp motor #14 wire is good for up to 150 ft, service entrance to motor. House sub panel cannot use the typical residential service cable size because inspectors here say it’s not a ‘service’. If the 125a subpanel were fed from a 90a breaker at the main panel, and the calculated load was <90a, then #2 al could be used,.
