I removed an island with an electric cooktop. I installed a new electric cooktop approx 9 feet away. I cannot get to the wiring under the house so can I just add 9 feet to the existing wiring and hook up to the new cooktop. It is 220

Is it 240v, or 120/240v? It should say on the unit.

What size circuit does it require? Or better yet, what is the actual draw (amps or watts)? Again, it will say on the unit.

What type and size of wire is it existing?



Simply saying "220" is worthless without other information.

It is 240 and it is on a double breaker "30 amp"
Again, All I did was replace it with the same unit only newer and I just changed the location but the wire would not reach the new unit so I installed a box and made a connection with the same wire "10/2 w/ground and ran it to the new unit.
Just wondered if that was OK or a single piece of wire from breaker to unit was required.

Hi apache

The joining of the wire in a box is OK. The junction box has to be accessible, can not be buried in wall or floor.

Good luck

My questions were valid because the codes have changed quite a bit in the last few code cycles. Not all household cooking appliances are straight 240v. Many are 120/240v requiring a "4-wire" circuit. Older ungrounded 3-wire circuits are no longer legal to extend or run new.

Yes, for a straight 240v 30A circuit 10/2 is fine. Creahands is right about the box being accessible.

You obviously did this already and are just looking for confirmation now so the point is moot.

Assuming the extension is installed according to code, which means splice was mad in an approved box, cable is protected from physical damage, properly supported, etc. you should have no problem.
