No, you can easily hook up an entire Seaton multichannel set-up, and play at high levels without special electrical needs.
That said, it all depends on how big your HT is, and how loudly you like to play at sustained high levels.
I've purposely checked to see how much ... 6kw up front (3)Cat12Cs, 4kw in surrounds, 4.8kw in SubMs, plus an quad 18" IB sub, in 3000cubic feet, 16kw plus, one residential circuit.
Sure, there's benefits to be had with dedicated circuits, etc., however these amps are very efficient.
Mark Seaton is on record; "My personal preference is to design for about 1/4 of the main speaker power and 1/3rd the subwoofer power to insure nothing is of concern and allow for more future possibilities."
So one would de-rate the 2kw Cat12C to 500w (3 on a circuit adds up to 1500w, with room left)
Likewise the 2.4kw SubMs de-rate to 800w each.
In my opinion, it takes sustained test tones and the biggest and deepest soundtrack special effects played at high levels in largish rooms would elicit an issue.
I recently explained this issue at length;http://www.avsforum.com/t/1506443/4-lms-5400-recommended-cabinet-build-recommendations-welcome#post_24094712
