Wire size for 100 amp sub panel 50 feet away.

Your panel and wire size. The breaker must protect the wire based on its amp limits. However, if that breaker is not made, you round up. So at your size, it's a labeling game. If you are ferociously committed to calling this a "125A" feeder, then you must use 2/0 aluminum wire (since 1/0 is only good for 120A).Example: Let’s say you want to use 200 amp service 100 feet away from the sub panel. We already know that such a circuit will require wires with at least 250A ampacity. On top of this, we have to increase the amps by 20% to get the true size wire for 200 amps at such a distance: 200 Amp Wire (100 ft away) = 250A × 1.2 = 300A Ampacity100 feet away #0 AWG wire: 150 feet away #3 AWG wire: 200 feet away: 2/0 AWG copper wire: 400 feet away: How to determine a 100 amp sub panel wire size?
