Wire gauge is directly related to how many amps you need to run through it.
Should I use 12 or 14 gauge wire?
All branch wiring should be rated for equal or higher current carrying capacity as the circuit breaker feeding that branch system. Example: If you’re wiring a branch fed by a 20 amp circuit breaker, use #12 AWG NM wire. For branches from 15 amp breakers, use #14 AWG NM wire.
