Which size of fuse or circuit breaker would be appropriate to use with a circuit that uses AWG number 14 wiring?

Erklärung

The same table read the other way gives the answer: AWG 14 copper is limited to 15 amperes of overcurrent protection, so a 15 ampere fuse or breaker is the correct pairing. Anything larger would allow the wire to overheat before the device opened.
