Temp construction power 240V

[pipe_bender]

I installed some temp power for a residential remodel, they are going to need a 240V floor sander so I put in a 50A 240V receptacle and some regular GFCI's, I had some other work inspected which passed but the inspector noted Temp construction power
"--Corrections needed provide copy of assured equipment grounding program or GFCI protect temp power."

The only outlets not GFI was the 240 one.
Do all 240V temporary outlets on a jobsite actually fall under the NEC ? I thought it was 10 - 30A 120V?
Its going to be removed before the inspector even returns but I deal with this town inspector pretty regularly so wanted to see if this was in the NEC or a local thing.

The inspector is 100% correct. That receptacle must either be GFCI protected or you must have a "written assured equipment grounding conductor program" in place. 590.6(B)

Don gave us the code section but seems if your inspector was going to write any kind of formal correction notice that it would note what code sections are in violation.

Do newer spider boxes have GFCI on their 240v outlets (usually an L6-30)? I don't think I've ever seen one that did but don't usually get the latest and greatest gear.

Around here the floor guys just take the cover off a panel and clip allegator clips to the buss. I offered at one time to make a cord with a dryer plug on it for them but that was no good. So now I just don't look.

I remember once when I was in an apartment building and they dropped their cord down from the roof elevator machine room. I just shook my head thinking about what would happen if they clipped onto 440.

All the boxes I have seen since the GFCI requirement come into effect.

Most of the time all the receptacles in the temp power (spider) box are double GFCI protected since the 50 amp receptacle feeding the box is connected to a GFCI breaker.

Thats interesting we have a two spider boxes we loan out to GC's the GFCI is on the 120V stuff only when did that change happen recently?

The rule has been the same back to at least the 1999 code, however in the 99 it was Article 305, and in the 2002 it was Article 327.

Temp power has required GFCI on up to 50 amp receptacles, I believe with wording stating 150 volts or less to ground or something similar, for quite some time. What is a little more recent is all receptacles up to 50 amps 150 volts to ground or less for all outdoor receptacles and even more recently for certain specific items or locations.

Thanks everyone I see it now

I was informed thats how this whole thing started the floor guys routinely do this and had been caught by the inspector and warned, now they ask GC for a temp 50.
