Bigger is better. When I wired my theater room, I actually ran three dedicated 20 amp circuits behind my stack. I also used hospital outlets. The wired that I used was 10 gauge bought at the local hardware store.
15 amps or 20 amps outlet
I'm in the process of installing a dedicated line plus Acme outlet in my house and was wondering if there's any benefits in choosing a 20 amps outlet over a 15 amps one. I have a Big 350 watts amplifier. Also, any advise on a good, not too expensive wire is appreciated . Thanks in advance.
