Hello,

I am moving my electric oven/stove while remodeling my kitched. It is a 30amp unit with 8-3 cable.

Question 1: Because I am moving the stove, I will need to extend the cable. Can I use a junction box and splice in the extension, or do I need to run a new cable?

Question 2: I have several lengths of 8-3 around the house, but none quite long enough. Can I install two junction boxes?

Thanks much.

 

Yes, you can use multiple junction boxes.

 

Copper or Aluminum? Both are splice-able, but you need to take more precautions with aluminum.

Personally, I'd consider replacing the whole run, or at least using only one junction. Every junction needs to be kept accessible and is a potential future failure point. As Ray pointed out, it's code-compliant, but not preferred.

Oh, and we are assuming you mean 8/3 cable with ground. You're not allowed to extend ungrounded circuits.
