GFCI outlet requirement

[thewire]

Outdoor cabinet outlet receptacle by the shed exposed to outdoor.

I want clarification on the NEC 590.6 (2) as it stated that the GFCI protection for workers shall be provided for all 125V outlet that is part of the permanent wiring for the structure but will be use as temporary power any power tools right? I need to have the GFCI outlet installed. My contractor however is arguing there is no requirement

Did i interpret the requirement correctly?

How about Article 110 Worker protection?

110 worker protection? I don't think the term GFCI even comes up anywhere in 110. 210.8 is the general GFCI protection requirements, there are other specific requirements in a few other places in the code though, including in 590.

But to some extent, forget about 590, if it is outdoors it needs GFCI regardless.

Now if it was installed at a time before it was required to be GFCI protected, you have more of an OSHA issue than an NEC code violation, portable GFCI device to plug into said receptacle will satisfy OSHA as well as 590 in such a situation with the use of an existing receptacle that doesn't have GFCI protection.

Older 110 C used to have the workers protection on GFCI but they removed it.
Where in the text stating it required? I can use 590 to support my claim. I read 210.8 I can't find a text on the outdoor thing.

There is and never was 110 C unless way back before GFCI's existed.

Sure you aren't thinking 210.8 (C)? 210.8 is where the general GFCI requirements has resided for some time now.

You guys may be forgetting that chapter 5 installations modify chapter 1 through 4 period article 590.2(A):

"Other articles. except as specifically modified in this article all other requirements of this Code for permanent wiring shall apply to temporary wiring installations".

590.6 does modify ground fault protection, however it is still required on temporary wiring.

If the temporary wiring becomes permanent, it is no longer an article 590 installation and still requires ground fault protection as per 210.8.

the wire, your contractor is wrong.

Yea I figured that out but i need in writing to show them unfortunately without change order


But Yea I found out it 210.8 3. Does cabinet considered outdoor structure?

Sorry it was Standard for Electrical Safety in the Workplace NFPA 70E Article 110 (C) 1-3

Correct and for 15/20/30 amp 120 volt receptacles it says:

Temporary receptacle installations used to supply temporary power to equipment used by personnel during construction, remodeling, maintenance, repair, or demolition of buildings, structures, equipment, or similar activities shall comply with the requirements of 590.6(A)(1) through (A)(3), as applicable.

Other temporary power applications or other ratings on receptacles may not need GFCI protection, though the fact it is outdoors kicks in some requirements in general back in 210.8 anyhow.

Plus there are a few additional applications in 2017 NEC than there was in 2014, in particular with receptacles other than 15/20 amp 120 volt, that don't need mentioned in 590 because the 210.8 would require them regardless.

OP did not clarify the intent of "temporary power" in his application but one can read between the lines to some extent and assume it is for construction related activity.

If this is not part of a dwelling unit:

210.8(B) Other Than Dwelling Units. All 125-volt, single-phase, 15- and 20-ampere receptacles installed in the locations specified in 210.8(B)(1) through (8) shall have ground-fault circuit-interrupter protection for personnel.
(1) Bathrooms
(2) Kitchens
(3) Rooftops
(4) Outdoors

If this is not part of a dwelling unit:

Correct, it need GFCI anyway. Now if you are using existing receptacle for construction that was installed before GFCI was required (hasn't been extremely long ago that 210.8(B) was changed to include all outdoor receptacles) then some authorities may require GFCI protection - 590 does allow portable GFCI devices to be used for this, 70E probably does as well.

Show them the Code articles I mentioned. The requirement for outdoor ground fault protection is numerous code cycles old.

And even if there was some possible exception, which I do not think there is, it would be liability suicide to put a non protected receptacle outside, where contractors are plugging in this and that, usually with the rattiest extension cords imaginable.

the other thing is we are not talking about a several hundred or thousand dollar change order, we were talking about a $20 weatherproof GFCI receptacle and maybe 15 minutes to install it.

Thanks all..They complied. They have to installed like 25 locations hence the fight initially

If receptacle is serving something inside may not require GFCI.

I have put communications equipment and portable control units in outdoor enclosures before with a receptacle inside the enclosure. Not GFCI protected. IMO it is a receptacle dedicated to that equipment and is not "outdoors". The portable control unit I am thinking of was tied to the machine control circuit and the simplex receptacle I used was also labeled that it was for the control unit only. If someone tried to use for general purpose they wouldn't have run much as the control circuit only had maybe 5 amp max fuse protecting it. There was other "outdoor" receptacles available as well for general use.


If supplying power for construction tools/equipment won't matter 590 will kick in for that purpose, even if using an existing non protected receptacle.

Yes those are not GFCI, it's most for the utility receptacle for any power tools, laptop, etc for the workers to plug it during work
