Here is our example.

Most modern homes have a 200 amp service at 240 volts.  Lets assume that our
amp will be limited to drawing 100 amps.  Gross power would be 240 volts
times 100 amps, giving 24 KW.  Since an efficiency of 60% can be reasonably
expected, we would realize about 14.4  thousand watts(14.4 KW) output from
our theoretical SSB amp.

If we permitted more than 100 amps draw, the output would increase
proportionally.  If we assume less than 100 amps, obviously our theoretical
amp would produce less than 14.4 KW output proportionally.

Any questions?

Hi Group,

If you run that kind of power (was that a typo) 32, 000 watts? you would 
need a separate power plant wouldn't you?
