Forgive me if it may sound rather silly, but is it okay to cap off several live wires for a short period of time? At the moment, they're wired to one of my signal controllers; however, they're not wired to an actual signal (they will be soon).
Naturally, I wouldn't leave them exposed when everything is live, so I'd think that a wire nut for each wire (including neutral) is adequate. Is this safe? I just want to be sure.
