Am I hearing things?

I just an extra  new dedicated line run beside the other one. with 10 gauge wire, 30 amp breaker and a 20 amp rated outlet. I don't think it sounds as good!!! What the hey. A little shrill in both vinyl and CD. I'm comparing from what it sounded like last night. Does electricians wire, breaker and outlet have to burn in? Am I alone in this. I'm have a whole system AC but in and the temp got up to 80. Maybe that is why. Also I'm listening at 11 am EST. So the power grid may have an affect. Did I just answer my own question or have other people experienced this. The original dedicated line was put in in 03 with 12 gauge wire, 20 amp breaker and a 15 amp outlet. Are these 2 lines picking up interferrence?

He probably put the 25 amp breaker on your AC unit which is not unusual that's about the only thing 25 breakers are used for AC units or water heaters.

I will get a polarity tester and I don't kniw tbe particulars. But I do know when I saw the wire it was orange 10 ga and there was no ground wire in it. So how could he ground it otherwise? I'm just going to get another electrician verify everything and quote this post. Thanks Mike

There should be white/neutral , black/ hot, bare copper/ ground. The ground might not be connected to the receptacle if there are more receptacles  on the run he might have twisted them together and crammed them in the back of the box. He should have pigtailed to the receptacle.

Stop. Take a deep breath. Don’t jump to conclusions. Other than the breaker the electrician installed in the electrical panel, everything else of the installation may be fine.

#10-2 with ground NM-B cable (Romex is a Trade name of) has an outer orange sheath, jacket. It comes with a bare equipment grounding conductor. It doesn’t come without an equipment grounding conductor.

The electrician installed one wall cut-in box and installed one 20 amp duplex receptacle. Correct? Metal or plastic box? Do you know the make of the duplex outlet? Is it at least a spec grade outlet? The outlet could be the source of the sound you are hearing from your audio system.  What type of duplex cover did he install? A flexible non breakable nylon plate?

Go to the electrical panel. What breaker number on the panel schedule is the older dedicated circuit you already have? What is the breaker number of the new dedicated circuit? The number is also stamped on the panel front cover next to the breakers. The numbers will tell me if the electrician install the new dedicated circuit breaker on the same Line, Leg, as the old dedicated circuit breaker.

Pick up a circuit/polarity tester at Home Depot. $5.00
