What is a 20 Amp circuit ?




I have ran 3 dedicated lines in my house for the stereo from the panel. I have 200 amp service in the house. Are these lines 20 amp?

I am no electrician , so can you tell me what constitutes a 20 amp line.

Thanks

Putty has it exactly right.

In most cases if you are not tripping your 15a breaker, there isn't a whole lot to gain by increasing it to a 20a. The increase in cable gauge, however, would almost certainly help, as it would cut down on circuit resistance.

I have run 10 guage wire to each component to cut resistance, but put in 15 amp breakers to help protect components not expected to draw much current. A 20 amp breaker when not needed is just adding to risk.
