Hello. Welcome to Just Answer.
The wire you've described sounds like service entrance cable, which is probably what the Home Depot clerk was talking about.
Ideally, you need to install a 3 prong outlet in that location.
Does the stove have a 3 prong cord on it?
According to the sales rep, the installers for the stove can use either a 3 prong or a 4 prong.
OK, with the wire you have in the wall, the stove should have a 3 prong cord on it. The wires coming from the wall need to be connected to a matching 3 prong outlet. There are surface mount outlets available. They typically have a black plastic box.
I can post a link to this item, if you need to see one. The outer braided bare wires need to be unwrapped from the other two conductors, and twisted together to form a third conductor.
ok, I thought the wiring would be block, white and green or a bare wire. This one has two black and a collection of bare wires. How do I tell polarity?
Polarity won't matter on the two black wires.
Huh, the homedepot guy said it should have polarity, but then again I bet he isn't a certified electrician.
Most likely not. With 240 volt AC circuits, polarity is hardly ever a concern.
Could you link the item you referenced? I think I know the item you mentioned.
Sure, can you stand by while I look it up?
sure thing. Let me post a pic of the wiring just so I can make double sure. ok?
Absolutely. Here's the type of outlet I'm talking about. You need a 50 amp rated model.
I don't think the image loaded properly. Did you use the paper clip icon?
yeah. image was corrupted by yahoo. sending it to my gmail account.
btw: that link is exactly what I was thinking.
Good. Any local home store should have them. If there is already a cord, just make sure the outlet configuration matches.
That is indeed service entrance cable. Just take all of the individual strands and twist them together into a third conductor. That will serve as your neutral/ground conductor.
awesome. thanks. I really appreciate your patience.
Oh, no problem at all. We're here to help.
going to rate excellent.
I appreciate that. Is there anything else I can do for you?
nope. be well man and stay out of the heat, or rain. Depending on where you are :)
Rain, at the moment. Messing up my outdoor plans, but puts me on this site, which can work out okay for customers, I guess. Have a great weekend!
