I had someone contact me(subcontractor for Hughes communications) about installing a GFCI protected outlet on the roof of a
C store for de icing eguipment used on a Satelite dish. They want a GFCI outlet in the store labeled "do not use, satellite eguipment only", then use the load side to go up and out to a single outlet on the roof. That part seems ok(although I had an outlet labeled"do not use" in another location that the oil companies insurance made me remove or allow use). It seems to me the exception to 210.8B allows for a dedicated circuit without a GFCI, which would limit nuasance trips. They say in their spec sheet that C Store employees should check to see if GFCI is tripped frequently
, like thats going to happen.
Of course I get this yesterday, its now -15 degrees with a windchill at minus 50. It seems real likely that I'm going to get on a roof and check this out
