I have a electric stove to hook up in my house that had a gas stove. The electric 50 amp receptacle is already in place from the previous owner. The existing stove “aluminum” wiring goes into the circuit breaker box, but the wiring is cut off inside the circuit breaker box and is too short to attach without adding approx. 3 foot of extra wire.

Can I add wire to the existing aluminum wire in the circuit breaker box (I would expect I would use copper wire, using a al/cu adapter and anti-oxidizing paste). Is it safe to do this? The wire going to the stove would probably be very hard to get to, to replace with copper.

BTW, the ground wire is already hooked up, in the circuit breaker box, so it would require adding two single wires to the 2 short wires in the circuit breaker box and adding a 220 volt 50 amp circuit breaker. (There is no breaker in place, so I assume the unit would take a 50 amp circuit breaker using this stove data).
10.4 KW @ 220
13.8 KW @ 220

Additional: The distance from stove to circuit breaker box is approx. 10 feet.

If deemed safe to add the copper to the existing aluminum wire, what size wire would I use? Is the determining factor the 20 foot distance of the aluminum plus the 3 foot of the copper. I figure 6 ga would be acceptable.

Thanks.

I finished the job and all worked out great. Using 6 Ga. Wire and a wire coupler with the grease and taped everything up. Looked as professional as the rest of the circuit breaker jobs in the box.
