30 AMP OPS

[Gregory OConnor]

Pete, "With your 30 amp 220 breaker at the house you have 30 amp
available on each leg (red , Black) but not at the same time. " you
can draw 30 amps through that breaker total. ie; '30 on one leg and
zero on the other' or '15 and 15'. or run a total of 30 X 110 =
3,300 watts. By design the breaker will trip if you draw more than
30 amps in any combination. You could simply replace the breaker
with a 50 amp if you have proper rated wire leading up to the bus.
Nothing wrong with leaving it 30 and managing the watt/ amp usage in
the bus.

I wonder if there is a way to hook into 110 30 amp and use the
inverter to make the other leg for the cooktop?


If you hook into 110 30A and turn on the cooktop, I wonder if the
electricity will pass to appliances on the other leg? I have seen
this happen, the cooktop rehostat became a light dimmer for lights on
the dead leg.

My electrical certification is limited to a merit badge and education
I credited to a 'how to do it book'. Titled "Don't be shocked by the
shorts"
