240V Range - Part 2
I'm about to give a friend advice on if he should purchase an electric or gas oven. I want to make sure I'm right.
He has a 40A Circuit, 1 Black, 1 White, and Bare Ground.
This doesn't sound right to me. I think (For 3-Wire Grandfathered Rule)
It should be 2 Hot Wires and 1 Insulated Neutral.
So should I tell him "No Go" on the Black, White and Bare Ground??
Thanks.
(He had an electric oven there before with clock and controls, could these controls have been 240V??)

My Bad,
This is a free standing range, or a slide in.
I don't think you're going to find many (or any) ranges running off straight 240.
Agreed? Should he even bother looking?
Thanks.

This is going to depend on the wiring method. If you have SE cable you have two hots and a neutral.

But, if the cable is NM cable (aka romex) such as 8-2 w/G or 6-2 w/G it was never compliant and must be replaced with a 4-wire circuit
But I always want to learn more. If someone has the time:
I looked at SE Cable, It looks the same as Romex to me. It has insulated conductors within sheathing, with ground.
What's the difference, Colors of Wires within? Or maybe the configuration of wires? I noticed SE is wrapped in plastic and then sheathed. My best guess is that it can withstand higher temps.
Thanks for your time.

SE cable was listed for use for stoves. The bare could be used as a neutral. Type NM cable was not allowed to use the bare as the neutral.
