Sort of. Amps per leg, so if you have a 100 amp feed,
that means you
have TWO 110 volt legs each rated at 100 amps. You can hang onto that
200 amps worth of 110 volt loads, or 100 amps worth of 220 volt loads,
or some blend of the two (provided the 110 volt loads are well enough
balanced across the two legs that neither hits its individual 100 amp
limit).
So you still have to multiply the rating by 240V to get the watts.
Some US homes have only one leg (just 110 volt) but I
think that's
only for ancient 30 amp and maybe 60 amp feeds; 100 and 200 are always
"two phase".
So we're pretty close to Gordon.
I figured.
