Is this cloth aluminum wire? Safe?

What twist are you talking about? This round conductor serves the same purpose as the flat jumper shown in the post by Roger. It does not need to be twisted or stranded.

It is not the jumper I am talking about!
It is the tinned copper neutral in picture #2
I date this at 1940s so for this reason I don’t find it acceptable for a new stove appliance.

The way the neutral has been made up has nothing wrong with it. There is no reduction in function. It also needed to be unwrapped to allow the hot conductors to be terminated. The field made twist just serves to groom the conductor and keep it from flying all over the panel. This is no different than how a neutral in a SE cable to a service panel would be made up.

Under the NEC a 3 wire range install can continue to be used as long as no changes are made. What do you perceive as the issue?

Would you consider it acceptable were it not for a new stove? What about the installation of a new stove makes it become unacceptable?

That branch circuit for a range is still permitted even if a new range were put in place. It would be covered under the exception in 250.140.

Thanks for the info!

Most of the ones I see damaged running through the floor and not inside the wall. The cloth covering generally is damaged and exposed. If I was an electrician I would not use the original and run a new one. I think a client would agree whether it is allowed or not. Again it all depends on the condition of the SER. I am not saying it has to be changed only the AHJ can make that call.

I doubt many homeowner would want to voluntarily add several hundred dollars to the cost of the stove to change the wiring.

Mr. Meier is correct in that there is nothing that requires the changing of the range conductor. And an AHJ is not involved in simple range changeouts, at least not in the US.

Running a new range wire could be very complex and require disassembly of walls, ceilings or floor components. Unless code or safety dictates, most electricians do what they are paid to do; and they wouldn’t even be involved in setting a new range. Using your reasoning, about half the homes in America would need to be rewired when a new range is installed.

Not inside a wall but exposed going through the floor or wall. This has been changed here and not recommended by InterNachi. I am not saying any need to be changed unless you see the damage and report it.
Here is a picture of what I mean.

Obviously wrong and should be called out. But that is modern cable, not cloth covered range wire or SE cable as we have been discussing.

Canadians please note this would not be allowed in Canada .
Stoves in Canada require 4 wires two hot a neutral and a ground .

I am just pointing out what is not acceptable here whether it is cloth or new. I do have pictures of cloth doing the same and opted to put the new one to show what an electrician has done here. As Roy has pointed out it is not acceptable here.

Several. Here’s a couple Siemens load centers.

Please note if it is cloth 4 wire and in Good condition it is OK .
Do not get your self trouble buy saying is is not … Roy

Good point Roy!
And thanks christopher for the actual pictures.

Canada requires you to bring an older home up to today’s code?

Roy, were 3 wire stoves ever allowed in Canada?

Not that I know of . Most of our Stoves have a 120 volt plug on a timer … Roy

Be interested in Knowing where you got that Information . I do not think that is Code … Roy

Roy, the above was a question not a statement, based on your post here that implied 3 wire conductors are outlawed.
