OUTDOOR GFI

[Patricio]

I understand that 2014 NEC allows a 2 wire 120 volt outlet and any outlets downstream to be changed to 3 wire outlets, provided GFI protection is provided at that particular point in the circuit, with the condition that all 3 wire outlets are marked "NO GROUND PRESENT". If there is no ground present at an OUTDOOR outlet, is it still permissible to install a GFI outlet, providing a proper in-use cover is utilized?

The "no equipment ground" stickers normally come with the GFCI receptacles.

Yes it is permitted to install an exterior GFCI receptacle on a 2-wire circuit.


Now if you do this for say a home inspection it still may get written up as a missing ground. I wonder what they think that "no equipment ground " sticker means.

If an outdoor GFI (not Leviton) is installed on a 2 wire circuit, and the electronic circuitry wasn't functioning, which is more common than one might think, would not a very dangerous condition be present if a fault current was ever present? Perhaps an outdoor refrigerator?

Yes, but no more dangerous than without the GFI in the first place.
For outdoor use I would be more inclined as a design goal to do whatever is necessary to run an EGC to the receptacle.

Thanks for your input, GoldDigger

Older gfci do fail, and not always in a failsafe manner. New gfci's are much better in that if they fail, they wont energize or reset.

Don't forget that the new replacement grounding-type receptacles must ALSO have AFCI protection (unless you have local ordinance to the contrary).

And you can't use any of the appliances listed in 250.114 from that non-grounding receptacle.
