As opposed to just sitting there, all pretty and nice, cool to the touch, looking all sweet an innocent?
Folks here are complacent about home theater demands and their electric service. There are far too many house fires because of overloaded circuits. This is a well known homeowner problem and it's not wise to poo-poo or ignore issues of this kind when adding lots of way cool home theater gear, including high watt, outboard Amps.
Back in the 50's, 60's and 70's, houses didn't know what home theater was and in the 70's, rare was the home which had met a home computer. Most homes were built in those days with five, ten and fifteen amp circuits as lvrms, at most, had some 100w incandescent lights coupled with a tubed 25" TV and maybe a low watt, amplified stereo system. It's a different day and age which many houses were not built to safely deal with. Today, with portable heaters/AC units, lights, ceiling fans and home theater systems, quite easily, these appliances can suck 1500w out of the wall. At 15A, which most houses are wired for, if your service is 120v, you're 300w from max. You have more headroom with a 20A circuit. Unbeknownst to most people, wires are intended to heat up. If you're at the end of a long run, stating the obvious, you'll have more resistance and more heat will build up. Not good.
It makes sense to discuss the reality of this well known issue. It makes no common sense to poo-poo the discussing of this issue and discourage the spending of a service charge to have your wiring checked out by a professional.
Let's say, ninety-five out of a hundred times, the professional finds nothing and I'm wrong, what does anyone tell the five out of a hundred who's house burned down whom they discouraged the spending of a few bucks to have their house wiring checked out; "Gee, I'm sorry I caused you to burn your house down?"
Old people have little to no tolerance for bad advice and people who feel comfortable giving bad advice. Experience dictates that well we shouldn't. Preventing people from making judgement errors is a good thing. Encouraging people to make bad judgement calls is a bad thing. Making fun of people is jerk behavior, we all know it and we all teach our children to be better then that.
