Emo say that it needs dedicated circuits but I imagine that is just ass-covering. It might trip the breakers if you ran a sine wave through it at max power for some time, but I can't see it happening on regular content. Also, with my marketing hat on, it is a nice idea - to suggest that it is such a beast, with so much power, that it needs circuits that mere 'ordinary' amps do not. They don't say that about the XPA-1 and that is a 500 wpc (8 ohms) unit - and the minimum likely number anyone would use is two.
AAMOI, here, running off a 13 amp circuit (UK standard) I have:
1 x Onkyo 5509 prepro
1 x XPA-3 amp (300 wpc (4 ohms)
2 x UPA-2 amps (about 200 wpc each (4 ohms)
2 x Seaton Submersive subs (1,000 watts each)
1 x Crown XLS 1000 amp (bridged into 4 ohms - 1,000 wpc - driving Buttkicker)
1 x 65 inch plasma TV
1 x Oppo BD player
1 x Panasonic BD Player (modded for all regions)
1 x Toshiba HD DVD player
1 x Mac mini (running HTPC)
2 x 4T hard drives in RAID config
1 x DVDO video processor
6 x cooling fans
The various players will not all be playing at the same time, but they are all powered on at the same time, albeit in standby.
Not once I have ever managed to trip the breaker with all that lot running at full chat, close-to-reference levels. According to the gadget that monitors the circuit, the maximum current draw has never exceeded 8 amps. Usually it is way lower than that - the 8 amps is a peak - it might have only been achieved for a second or so, once.
The domestic circuits do not trip the very instant they see a max current draw anyway - they have a fair tolerance to momentarily being overloaded. If they do overload properly, there is no danger - the circuit breaker simply trips. So anyone contemplating an XPR-5 would soon find out, during the return window, if it was too much for the circuit it is on because their breaker would trip.
