Extending a 240v dryer circuit
I have a simple question that I most likely already know the answer to, but I'd like to verify it anyway.
I am moving an electric dryer from the basement to a newly finished laundry room on the first floor. I need to extend the 10-3 line from the current location to the new location, which is a total of 15 feet away.
Is it OK to simply add 15 to the existing 10-3, using wire nuts and a junction box, or do I necessarily need to run new 10-3 all the way from the breaker panel?
I don't see a problem with simply extending that line, but I just want to make sure it's doable.
Thanks.
