When are GFI outlets used?

Are GFI outlets only required at wet locations? What locations need GFI's. Isnt it best to have GFI's for all outlets...or is this just overkill and expensive?

GFI outlets are required within 3' of a wet location, so all bathrooms, kitchen counter outlets, exterior, and garage must be GFI protected. The outlets themselves do not have to be GFI, but the circuit must be protected by one, which is why they're actually called GFCI, or Ground Fault Circuit Interrupter. The way this is done is that the first outlet in the circuit is a GFCI, and then the remaining outlets are fed from the first, daisy chain style.

New code requires AFCI protection for just about every where a GFCI's are not specifically called for. There are a few exceptions.
Both type of protection can be accomplished with AfCI or GFCI breakers.


Re: When are GFI outlets used?

Great question! As stated, GFCI 's are required just about everwhere around water usage, except: garbage disposals, dish washers and washing machines and probably some more. GFCI's have been a tremendous success.

It's funny, labels are now showing up on standard GFCI's saying something like "not to be used in wet locations":) Now outside locations require "Weather Resistant" (WR) GFCI's.

Both trip power to a circuit (or receptacle) if current returning on the neutral is not very close to what was measured on the hot. Which means that current has either leaked off to ground, or someone is being shocked.

It would be great if GFCI's were used everywhere but a lot of appliances still have too much to allow that. Which is why AFCI manufacturers are removing ground fault protection from their devices, to prevent non-arc fault tripping and bad publicity.
