self grounding receptacles and GFCI
What are self-grounding receptacles and do they really provide a ground for a previously ungrounded outlet in an older home?
Does putting a GFCI outlet at the start of a circuit protect all of the outlets on the circuit? (I sort of picture a GFCI outlet at the first outlet in the circuit as an extension of a GFCI circuit at the breaker box).
I've read on this forum about surge protectors at the panel. Is there one protector for the entire panel or do you need one for each circuit?
I've done a quick seach on these topics and I suspect that the answers to my questions are buried here and there in various threads, but I'd love to have my questions addressed in one new thread. (I've asked similar questions before on this forum, but I'm guess I'm a little dense and it hasn't all sunk in or come together yet for me ).
