Here's the situation:
A client has an electric cooktop (two-burner w/broiler) installed in a countertop outisde the house, in a covered patio. The unit is supplied by a dedicated 30 amp 120/240V branch circuit. The branch circuit cable has an equipment grounding conductor (it's a four-wire cable)
They are wondering if it'd be appropriate to use a GFCI breaker to supply the cooktop.
I say it's not required by Code, and wouldn't be a good idea, as there may be sufficient leakage current to ground (the frame of the unit) to nuisance trip a GFCI. Any GFI would have to be designed for the 120/240 circuit, of course.
Anyone have any experience with this sort of situation, or a different take on it?
Thanks in advance,
Cliff
