Amplifier power consumption (1 Viewer)

[ScottH]

In researching power amps over the last few weeks, I've come to realize that I will need a dedicated circuit just to power the type of amp that I'm interested in getting (5 channel home theater amp). My concern is that I'm not sure my current setup will allow that. Has anyone had this issue before?

How many Amps are you looking to draw? At one point I had a Denon 1801(4.5A), Rotel RMB-1066(700w), 32"TV, DVD, Paradigm PS1000 sub all on a 15A line. No problems. Replace my Denon with a Marantz AV560U pre/pro and saved 4.5A. I will be adding a dedicated line in the near future anyway.

Just one multichannel amp, although one of the ones I'm considering is the Sherbourn 5/1500A, which from what I hear is technically 5 monoblocks. According to the website, it runs at 110v/60 Hz or 220v/50 Hz. You'll have to excuse my ignorance as I know absolutely nothing about electricity other than that I need it. A lot of it.

Scott,
Unfortunately I needed a dedicated 20 circuit for my amp too. I just had too much gear running of my main HT circuit. A 20 amp circuit can supply 2400 watts on a 120V system. My amp would have put me over that.
20 amp circuit #1
Receiver 672w
CD Player 11w
Satellite Receiver 35w
VCR 23w
DVD Player 14w
LFE sub #1 12" 250 watts(uses 350w from outlet)
LFE sub #2 12" 250 watts(uses 350w from outlet)
Left surround sub 10" 150 watts(uses 180w from outlet)
Right surround sub 10" 150 watts(uses 180w from outlet)
Total: 1815 watts
20 amp circuit #2
Amplifier 1600w
RPTV 336w
Total: 1936

How may watts will each 20 amp circuit be able to accomodate within a good safety area?

If I remember correctly. Your supposed to leave 20% free for saftey reasons. So on 20 amps I guess you shouldn't exceed 1980 watts.
