a 20A outlet on a 15A circuit, otoh, would be a BIG no-no...
i agree he'll be fine in terms of available juice though...
Which is what I posted in my comment as I differentiated between 15A outlets vs 20A circuit breakers so I don't understand. It's the total watts being put on a circuit and the more demand, the more heat generated in the walls which do cause house fires. Especially if standard duplex outlets are used. As I have work done on the house I have any electric outlets upgraded to "hospital" grade, 20A outlets so the chance of there being a problem are minimized. It's not nice to understate valid concerns and warnings. The electric code has not caught up with the demands of today's home entertainment center. I don't agree about being fine as I see valid concerns regarding the addition of outboard Amps being dismissed out of hand.
If one is going add a high wattage amplifier to the same circuit the rest of the home entertainment system is connected to, if one does not wish to chance burning the house down unnecessarily, thoughts should turn to adding separate circuits for safety's sake. Money well spent.
My concern, many people don't seem to understand that today's house wiring is not up to standards necessary to be able to handle the amperage requirements of today's home entertainment centers. Where the total wattage of television, Blue-ray player, powered subwoofer and the addition of a high amperage home theater amplifier, can easily reach/exceed a standard homes wiring ability. This point is compounded if the house wiring is older and all circuits are on five, ten and fifteen amp services. When one reads of the possibility of home wiring exceeding capacity, comments of concern/warning should "RIGHTFULLY" be posted as that's the "RIGHT" thing to do. Should someone add additional lighting or heaters to the circuit, easily, the capacity of the circuit will be exceeded. Understating concerns is not the right thing to do as that's how houses are burned down.
"Warning, Warning, Warning Will Robinson!"
When one adds high amperage outboard amplifiers that alone can exceed 15A or the capacity of a cheapie $0.99 duplex outlets, comments about the need to add independent circuits to handle home theater requirements for fire safety purposes, "NEED" to be posted. Comments about upgrading duplex outlets to "hospital" grade duplex outlets, need to be posted. If one wants to chance burning their house down, that's on them but it's "WRONG," when one knows better, not to post "REASONABLE" concerns.
Why anyone would poo-poo "VALID" warnings is beyond this old man's comprehension.
