Hullguy,

I'd certainly be interested in an explanation.

I checked the power panel and everything is grounded as it should be, all the screws are tight and there are two ground cables that come into the power panel (the one is attached to a rod, driven into the ground, at the other end of the house. Where the other ground cable comes from, I can't tell.

I removed the doorbell transformer from the circuit and no more buzz in the panel. Also, I don't know if it's my imagination, but from my seating area, I can no longer hear my amp.

However, when the compressor was running in my fridge, my amp seemed louder and when it turned off, it was quieter, within the moment! Is this actually possible? Or, is it just my imagination?

Sorry, didn't mean to veer off topic.

I did the math; if I add all my AV components together, max draw is 3,000 watts. I can't imagine coming even close to this kind of draw, however and so how should I judge my requirements? Should I just shoot for the 3,000 watts, which I thought was 30amps?

I like the idea of the UPS, but the professional AV installer insists that the Surge-X is the` thing to have, the way to go. The pricing is comparable. Also, that 70lb UPS is just not happening in my small living room, with two, continuously running, 5� computer fans. If I could keep it in the basement, safely and interconnect, that might be an option, but I can�t see how, without making a lot of holes.

Again, I appreciate the input from everyone here; I thank you all. I�m enjoying this, also, always love to learn new things.
