The reason that Outlaw recommends a dedicated circuit for some of their amps is that to achieve the rated output from multiple channels at once, you would need all of the current available from a single circuit. The circumstances that would produce such a current draw are actually quite rare in real life, though. I'll offer an example from my own system: my PF60 serves a 990, a 7500, two Model 200's, a 32" CRT HDTV, an LFM-1 (the original Outlaw sub), an SMS-1, and about half a dozen source components (HD DVR cable box, DVD player, Blu-ray player, HD-DVD player, DVD recorder, VCR, and a Roku Labs SoundBridge). Speakers are Paradigm Reference mains, center, and rear surrounds along with Axiom side surrounds - none of which are exceptionally efficient. When playing at reference levels, the PF60 typically reports no more than 7A of current draw. At more modest listening levels, that draw can routinely hover around 4A. As a result, there's no need for me to have a dedicated circuit for my power amps.

Great, thanks gonk.
