FAQs
What Size Wire Do I Need For A 100 Amp Service? ›
Typical sizes of wires for 100 Amp Service are 4 AWG or 2 AWG for copper wiring and 2 AWG, 1 AWG, or 1/0 AWG for aluminum or copper-clad wiring. These sizes are also used for direct burial. When choosing 100 amp service wire size, remember that a 100 amp circuit at 240V can proceed up to 24,000W of electricity.
What size wire do I need for 100 amp sub panel 100 feet away? ›A 100 Amp branch circuit would require #3 AWG Cu or #1 AWG Al wire. A single phase circuit would have 3 conductors, a 3 phase circuit would have 4 wires. If using PVC conduit add a minimum #8 AWG Cu ground wire.
