Apologies in advance for my almost complete ignorance of electrical issues!
As part of a whole-house rewire, I had the electrician add two #10 independent ground runs to two brand new Power Ports for the hi fi.
I hear buzz from appliances on other circuits in the speakers, and switching box fans on and off creates pops (these are also on other circuits). I can also hear a buzz from the power supply for the turntable when this is switched on.
All the audio gear is running into one receptacle through an older Chang power conditioner (saving up for a Power Plant).
I’m assuming this means that the new circuits have been wired incorrectly, as I thought these new (apparently) IG runs would eliminate noise from the other circuits.
In advance of talking to the electrician about it, are there any obvious ways this could have been mis-wired to create the above problems?
Thanks also in advance
