The vanishing gfci's

[ryan_618]

In my state we require an inspection for temporary power before giving clearance to the POCO for a meter set. As per article 527 we require a GFCI on the 240V, 50A receptacle outlet. I notice that almost every time, as soon as I clear it to the POCO, the GFCI breaker gets removed and is replaced with a standard 2pole50. Does this happen to any of you inspectors out there and how do you address it?

ryan,
On what basis can you require a GFCI on a 240 volt circuit?

Don, I don't have my 2002 NEC here and won't for a bit because I'll be on vacation. I beleive article 527 of the 2002 is the same as article
305-6 (b)in the 1999 was. This is for a temporary pedastal, bare in mind. EDIT: Maybe I understand now. We don't REQUIRE that you have a 240V GFCI receptacle, we just require that if you do have a 240V, 50A receptacle that it be GFCI protected.

Ryan what is the 50 amp outlet for?

I ask because if this feeds a temp power distribution box IMO having it on a GFCI is a bad idea.

A ground fault in any single circuit could take out all the circuits.

For a 50 amp outlet 1999-305-6 (b) or 2002-527-6(B) allows GFCI or the assured equipment grounding conductor program.

Re: The vanishing gfci's

Bob, as always, thanks for your reply. I only have this problem on residential applications. I don't think the assured EGC program as really valid, considering that the electricians are only on the house for a limited amount of time. The receptacles in question are installed from the factory in a temporary pedastal. They are generally used for an air compressor or large saw or whatever kind of equipment needs it. On commercial jobs I discuss the options of GFCI and EGC assurance with the electrician as an option, but not on residential.

ryan,
The electrician would have nothing to do with the assured equipment grounding program. That is the responsibility of the contractor who is using the equipment. I think that many times the cords used to power this 220 only equipment are using the grounded conductor for the equipment grounding and this would trip the GFCI protection. This would be one reason why the GFCIs are removed.
