I've got a RV garage for a homeowner that will have 9 regular 15 amp 120 volt outlets and 1 (30 amp)120 volt RV outlet. There has been a 30 amp circuit wired on his new house and brought out at the back of his house to feed this garage. I will have to trench over to the building with the feed. By code I can't put a 15 or 20 amp outlet on a 30 amp breaker. If I pull the circuits into a small breaker panel and break it down to 20 amp circuit for the regular outlets and a 30 amp breaker for the RV outlet, I can't use the regular 15 or 20 amp GFCI recpt. to protect it. Since I don't know of a 30 amp GFCI outlet, I guess the only way is to get a 30 amp. GFCI breaker in the panel to protect it. Am I right?? Thanks...
John, the feeder has already been run to supply the building. The owner says that one circuit will be sufficient, since he will never be using more than one outlet at a time. It will be 120 volt 3 wire feeder ( 10/2 with ground). As I said, my only problem seems to be the rating on the receptacles. As I see it, I can't install regular 15 or 20 amp 120 volt receptacles on a circuit that has a 30 amp breaker feeding it, so the only way I see of remedying it, is to set a small 2 circuit panel, feeding it with the 10/2, coming back out of the panel with (1) 20 amp circuit to feed the regular 15 or 20 amp receptacles, then coming back out of it and feeding the 30 amp RV receptacle. Thanks.. Steve
OK, I've seen 10/2 run to a small 4 circuit panel. Grd bar, neutral bar, and the 'hot' jumped from one line lug to the other.
It had 4 single pole cbs, 2x15 & 2 x20 amps, going to GFI receptacles. (old detached garage). Our CCO inspector eyeballed it, and the HO could not produce any documentation. He confessed that it was DIY.
Did it work? Yes. Was it compliant?
Jumping from one line lug to the other. 2 conductors under a single lug. 110.3 (b) panel labeled as 120/240 3 wire.
Now, the 'panel' was an FPE, and the panel in the house was also FPE.
Did I red tag it? No. He called an EC. 20 amp cb on the feeder, panel trashed; 14/2 (15 amp circuits) removed; 12/2 to daisy chain GFI outlets. Case closed.
Maybe I missed it John, but is it against code to jumper two legs with 120 volts? Under the circumstances, I don't see any other way, unless I try to get away with 20 amp recpts. on a 30 amp breaker. I can't send 240 because it has no neutral...Thanks
