I replaced out the sub-panel in the above posting to include a MAIN breaker and additional spaces. Since this Sub_Panel is in a detached shed and it has more than 6 breakers code requires a MAIN Shut off in the panel. I now have a 60 amp MAIN breaker in the panel as marked.
Did you make sure your pumps won't run at the same time as your EVSE? Just pointing out that if everything's running at the same time, you'll trip your 60A main breaker.
It’s been over 2 years since I installed the 40 amp line for the EVSE and it’s never tripped the home 60 amp breaker that feeds the sub panel. I did measure current draw before installing the 40 amp line to insure that I had capacity.
As measured the Pumps draw 6-7 amps each and EVSE draws 30; amps. So with both pumps running and the ESEV charging the current draw maxes out at 42-44 amps.
Plus the car is programmed to charge overnight while we are sleeping, so rarely do either pump run because no water is being used.
I actually occasionally but rarely plug my RV into the 14-50R receptacle. Even with both AC units running in the RV (separate 120v legs) and water heater on electric it never exceeds 30 amps per leg. Even thought the 14-50R line is wired with 6AWG and can easily handle 50 amps I protected the line with a 40 amp breaker rather than 50 amp to be safe.
