If I use GFCI breakers do I still need GFCI receptacles? Also I see some combonation AFCI / GFCI breakers. Are these reliable? And my last question of the weeek. Is the home run in a branch circuit a seperate neutral wire which connects the last receptacle / switch to the neutral bus?
If you use a GFCI breaker, you don't need GFCI receptacles. As long as the breaker provides the level of protection required at the outlet.
Dual Function Circuit Interrupter (DFCI) breakers are reliable.
"Home run" is not a technical term. It may be used to describe a dedicated circuit, where the circuit only supplies a single device. It may also describe branch circuit conductors, that run uninterrupted from the panel to the first device.
