Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) What is the voltage of the circuit and the amperage of the circuit breaker?

2) How is the circuit wired? NM Romex cable, metal or PVC conduit or metal clad cable or other?

3) Any lighting on the circuit or only receptacles?

4) How many receptacles on the circuit?

Expert:  Kevin replied 19 days ago.

Thanks for the replies.

1) I would need to understand the specifics regarding the existing wiring scheme before I can make a comment.

2) A quick answer is that, I always recommend when using audio equipment is to have that equipment reside on a dedicated grounded receptacle circuit that contains no lighting nor any other loads except the audio equipment receptacle.

3) The main electrical panel and/or the building also needs to be confirmed that no ground loops are present. Main panels and/sub-panels also need to be confirmed that they are properly grounded to a primary and a supplemental grounding electrode conductor and an equipment grounding conductor.

4) As you can see, there are numerous factors which can have an impact on audio equipment within the electrical distribution methods installed.

If you have any additional questions, just let me know and I’ll be glad to answer them for you.
