I just had a plumber install a new gas line to my kitchen so I'll be using a gas appliance for cooking. I'm leaving the 240v electrical receptacle in place as well as the wiring that runs in between floors to the subpanel.
I'm building a workshop in the side yard and I'm running a new circuit to the building from my original subpanel. Now that I will not use the old 240 v range circuit in the original panel, I want to disconnect the wiring there and cap off the wire. My new workshop service wiring will come into the original subpanel to a 60a breaker, taking the place of the 50a that protected my old electric range.
My question is, what is the code on unused wire inside the subpanel? I looked in the 2008 NEC and can't find any mention. Is it ok to cap with wirenuts and tag?
