Replacing an oven install

liquidvw

I'm replacing an oven in my house. It's a built in double oven. Before I buy the new one I wanted to check the electrical connection. The existing connection is a 50 amp double breaker. I have 3 wires going to the oven. Both the neutral and the ground connect to the unshielded wire. Whirlpool says that the connection must be 30 or 40 amp and I can use 3 or 4 wire connection but I have 50 amp is that OK??


208 volts) require a separate 30-amp circuit.

You can leave the wire and just replace the breaker to a 40 amp breaker.

A follow up question as I'm now just getting around do doing this project. The wire is 6 gauge AL. It was connected via wire nuts to my old oven. The new oven has a whip that is 10 gauge copper. I don't think these wire nuts will fit over both wires. With that said, is split bolts the best way to go. If so what's is the proper wrapping procedure and what type of tape?

Also, would Polaris connectors be a better choice?

Thanks in advance.

Are you sure it is Al? Older wire has a tinned surface that looks like Al, but if you look at the cut ends, you will see it is copper.
If it is Cu, I would use the large blue wirenuts.
If it is Al, you will need to use a connector that is approved for a Al-Cu splice, which may be a split-bolt or a set screw type connector.

Im pretty sure its AL. The cut ends are AL and the wire says AL on it. The house was built in 1997. Thanks for the reply.

I ended up buying the polaris connectors. They were expensive but real easy to install.
