Hello,
I'd like to add a 240V-only receptacle to my basement workshop to run two induction motor loads. I have experience running 120V household circuits, and I just have a couple questions on 240V circuits:
1) My understanding is that for NEMA 6-15 (240V 2-pole Grounded 15 amp) plugs and receptacles, the two hot prongs are undistinguished, i.e. there is no polarization as on 120V plugs and receptacles. Is that correct? Is there any convention?2) I believe the NEC does not require GFCI protection on 240V circuits. Are economic 240V GFCI receptacles available?
Thanks, Wayne
