50 amp service is 100 amp service, not 50 amps total.
we are not a direct total service connection.
we are a 200 AMP service to the house, and the RV 50 amp service is taken thru a 50 AMP C/B off the service distribution buss.
our RV service is limited to 50 AMPs.
This circuit is what allows RVs to have 3 A/Cs running along with HW, MW, charger, TVs etc.
With a Magnum charging at 125A DC it's AC input would be draw about 16A. That leaves 34A AC on that leg and 50A AC on the second leg.
The 50A label refers to the highest voltage (ie 240V) or 50*240=12,000W (watts). Your 200A house panel is similar 200*240=48,000W.
