New Cooktop question
 
I was reading the instructions for my new Jenn-air cooktop and it requires 240V and a 40amp breaker. I checked my panel and see that my current cooktop only uses a 30amp breaker on 240V. I can put in a new breaker, but do I need heavier wire or will I be okay? The house was built in 1986 in the burbs of Chicago. I assume I just need a new breaker, but you know what they say about "assume".

Thanks,
Matt

We install a certain size wire to serve a particular load. Then we install a certain size circuit breaker to protect that size wire. So I am going to assume your wire is number 10. Good for 30 amps. Number 8 wire is required for a 40 amp circuit. So you cannot just change the circuit breaker without also changing the wire.

But just to be sure, check out the existing wire and tell us what AWG it says...

That makes sense. Is it difficult to pull 8ga wire. How would you suggest I to swap it out?

first look at the existing wire and verify what size it is...

The wire is stranded 10ga

to OP sound like you are near chicago so therefore if so check the pipe where the cooktop goes it should be 3/4 inch emt pipe if so you are in luck but you may have to follow the path to see if there is no junction box in the middle of run i know it will show up one way or other so check it first before you yank the wire out.

once you see it clear to pull just tie new wire to the old one and guide it you will get there pretty fast with short run otherwise get a fishtape and pull the new wire after ya yank the old wire out.

IF this in NM romex then it get little more trickier let us know.

Merci,Marc

Get a licensed electrician to perform this task.

There is a junction box 10 feet from the stove that looks to be where the double oven and stove split off. There's no romex, it's all hard conduit with individual wires. I'll have to check again, but from what I recall, the conduit looked pretty full leaving the breaker box.

Is it alright to run a new line from the breaker box to the stove with BX 08-3 wire? Do they make it that large? Does it need to be in solid conduit? As a DIY project that would be the easiest but does it comply with code?

Way too many question that need to be asked/answered on this one.

If I were doing it and there was a conduit path back to the panel, I would do everything I could to use it.

With the proper technique there is always enough room :thumbup:




Pics are always good.

I've just called my electrician to come and pull the line. I appreciate everyones help.
