My question is this;
If we?re forced to use and install 80% rated circuit breaker then shouldn?t we be able to install the wire rated for 80% of the circuit breaker?
And if we use and install 100% rated circuit breaker then shouldn?t we be able to install the wire rated for 100% of the circuit breaker?
Example:
A 200 amp OCPD rated at 80% (160 amps) The wire should be sized for 160 amp.
And a 200 amp OCPD rated at 100% (200 amps) The wire should be sized for 200 amp.
Right or wrong?
