How many watts can I power with twin 30 amp electrical service?
My boat has twin 30 amp service. I’m wondering how many watts can I load up with my appliances onboard.
Update: System is 120 volt

you need to know voltage. Assuming a 12V service, 30A gives 12X30=360 watts. Twin gives you 720watts. That is not much, a typical microwave is about 1000W
consider loss if you convert to 120V with an inverter. You might get 500W on a 120V AC service.
If the orginal 30A service is already at 120V, that is plenty power for a fridge/TV/toaster...

A 30-amp outlet supplies 3,600 watts (30 amps multiplied by 120 volts). Therefore, the breaker on that outlet could meet code and still trip anywhere between a total load of 2,880 watts (80 percent of 3,600 watts) and 4,320 watts (120 percent of 3,600 watts).

Watts = volts times amps, so assuming a voltage of 110, you could run 3300 watts on each circuit.
