What Size Wire For A 60 Amp Circuit Breaker?

Choosing the right size for wires in electrical circuits is super important. For a 60 Amp circuit breaker, the best wire sizes are 4 AWG for copper or 3 AWG for aluminum. Why these sizes? Well, a 4 AWG copper wire can handle up to 85 amps and a 3 AWG aluminum wire can take up to 75 amps at 75°C. Using smaller wires can be risky even if they seem to handle around 60 amps because it's safe to use only up to 80% of a wire's maximum capacity.
