Question for you folks...
The wife is getting a new washer & dryer. The dryer's going to be electric (shock - I've had gas dryers since I was a wee tot), and it is suggested in the manual to install a 4-Wire receptacle .
I know that the "hots" go to each of the straight blades, the neutral (white) goes to the "L", and the ground (green) goes to the, well, ground shaped (D) terminal.
My question is - in a conduit system do you need to run an actual grounding wire all the way back to the panel, or can your connect a "jumper" from the ground terminal to the grounding terminal in the junction box? If the conduit is intact, is it allowed to act as the grounding conductor, or is conduit grounding only reserved for accidental fault purposes?
(Gimme a break - I've never had to wire one of these before - they've all been 10-30's.)
It's not that long a run to the panel (maybe 30'), so I'm going to run the grounding wire all the way anyway. I'm just looking for feedback.
