40A range aluminum feed save?

Hey there,

helping switching a range out and noticed that the cable is aluminum.

Is that still kosher?

I would put a box at the end of the existing cable so you can connect a future extension.

That's SE cable and was used for ranges for years. It's still ok to use a three prong receptacle on it for existing installations, but if the wire were to be relocated, it's a no go. All new, since either the 93 or 96 code, are to be four wire, which is also available in aluminum SER cable and used for ranges all the time. I've never used it, but if I have to run an oven circuit while the price of copper wire is still sky high, it's going to happen.

Aluminum is fine in that application. The aluminum issues were on branch circuits (like 15 and 20a receptacles and lighting).

Can also reuse it for a 240V only circuit.

Thanks guys for clarifying that for me.

Thetion AL is fine, but since the adoption of the 1996 NEC it's no longer allowed to install a 3 wire circuit for a range or dryer, it's only allowed to be used in existing installations, so if it was required to be moved, it would be required to upgrade to current standards.

If you wanted to use aluminum conductors to wire your entire house it is permitted by the NEC still, the only problem would be finding AL NM cable, the only material is NOS new old stock NM cable, but since the NEC has required NM cable to be rated for 90°C since the mid 1980's, and the old **** has a 60°C rating it cannot be used. Copper clad aluminum cable is making a comeback though, it has the economy of AL, & the ease of terminating connections of copper, Gimme copper Romex® over CU-Clad AL they can keep that ****. I was even reading of proposals to allow 14 AWG copper clad aluminum on 10 amp circuits in the next NEC, have to wait and see if that abomination comes to pass.

Looks like youre moving the circuit so as explained above, it needs to be abandoned and you will need to run a new 4-wire circuit.

If you use cu, you can go with 6/3 NM-b. But if you want AL, you will need #6 SER.
