how do I tie off an unused switch?

10 years ago

I am replacing the bathroom fan. The old bathroom fan had a heating function and a fan function on separate switches. Therefore, two sets of wires run to the fan in the attic.

The new fan does not have the heating function because we never use it.

I can hook up one set of wires (-,+, and ground) to the new fan without a problem. What do I do with the other set of wires running into the attic? What is a safe way to tie them off? Can I just wrap each wire separately with electrical tape? Do I put each wire in separate elec. nuts? How about the ground? Should the ground still be grounded? If so, what to? thanks.
