I have a 60A breaker feeding it. Technically if I'm splitting 65A * 0.8, I guess I should upsize 70A breaker using the round up rule, but it doesn't trip with 52A being drawn and nothing is running off the sub panel to actually exceed 60A for a non-continuous load. The wiring itself is good for 65A, so there's no fire hazard.What size breaker do you have feeding your sub? I was checking my setup and I'm going to be replacing a NEMA 14-50 plug so I may be limited to a 50 amp feeder breaker. So in this case I'm just trying to figure out the best approach to get maximum charging using power-sharing.
I'm thinking feeding the sub panel with the 6/3/ 50 amp feeder, then doing two separate 50 amp breakers in the sub and feed those to the wall connectors. Limit the power sharing to the two connectors to 40 amps and call it a day. Would that work?
You can do what you plan - but your wiring does support 55A. So you could theoretically install a 60A breaker feeding the sub, configure the two connectors to 48A, and set the network limit to 44A -- that will limit each connector to 44A (so you're not exceeding 55A * 0.8) individually and combined
It's been a while since I did the initial commissioning so maybe during that setup it has you select the breaker size. In which case set your breaker and the limit to what your wiring supports. The wall connector will draw 80% of that setting.You cannot set the WC to 48A, your choices are 15, 20, 30, 40, 50 or 60 so please elaborate.
During the power sharing setup, it asks for the actual current draw, not the breaker size. So set the power sharing limit to whatever continuous load your wiring supports.
