Water heater dump load AMPs
Well I contacted http://svhotwire.com again. Wanted to see if boosting the dump load AMPs from 20 AMPs which the Blue Sky Duo controller will supply to 40 AMPs would work with the 12v element dump load. There is an add on to boost the 20 AMPS to 40 AMPs by Blue Sky the CBM4070
John at Hotwire said the dump load will only use 25 AMPs so it would be a waste.
So there some more info not in the instructions that did not exist J, the instructions.
