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

The 200 ampere service is the current capacity of the main box that services everything in your house. A 20 amp circuit is a branch from that box that has a 20 amp breaker and at least 12 gauge wire to carry that amount of current.

Most of the circuits in your kitchen and bathrooms should be 20 amp.

...oops...

...and which has a 20-amp outlet on its end. Otherwise it's a 15-amp circuit.

If you are no electrician and are asking this question I hope you have had your work inspected by qualified electrician. Your insurance company would be concerned.
