Re: GFCI Breaker vs. GFCI Receptacle
1. The receptacle can be reset at the receptacle. This can be important if the circuit breaker is in a remote location.
2. It may be easier to install receptacles in a retrofit application, with a CB you have to make sure you know which is the correct neutral at the panel.
3. Cost, as a bolt on GFCI CB can be $100 or more
I like the receptacles as they can be reset locally. If I am running power to an underground vault that can flood I will use a CB.
Its really a end user choice.
