Hi all,

I am replacing a 20 year old electric range with a new one. The old one was direct wired with aluminum 3-wire cable from the two pole circuit breaker.

My understanding is that I don't have to change to 4-wire since this is old construction and it is not moving. While I understand it is recommended, replacing it would be very difficult.
​​​​​​
My other understanding is that I can direct wire if the range instructions allow it. This is a Samsung range. The instructions detail using "3-wire conduit" or "aluminum building wire". Is this the same thing?

If I am missing something, please let me know.

 

That connection block on the back of that range is not setup for aluminum wiring. I would highly recommend using a 3 wire cord and a 3 wire range receptacle that has lugs for the aluminum wiring.

 

Hi, I can’t believe they would even suggest using building wire in flex conduit to make that connection, especially Al. get yourself a cord and receptacle as PJ mentioned.
