Remember a dedicated line just guarantees no other loads on that circuit. But all circuits go back to the main panel and are ultimately tied together as are the grounds
Dedicated circuit picking up noise
I installed a dedicated circuit for my system, yet I'm still getting a hum through my speakers. Also, when I switch on a ceiling fan in the same room as my system, I get a loud pop. What gives? I thought a dedicated line would eliminate ground loops and isolate noise from any other circuit. Any ideas are appreciated
