I hope this is the right sub...
I have a 100A pony-panel in the garage. I'd like to have someone add a wall plug for EV charging, ideally a 14-50, but I'd settle for a 14-30 if need be.
I seem to recall there is a rule that any circuit can only be x% of the total supply. I further recall this being 25%? So in this case, I'd be limited to 25A?
Is this correct, or am I having a senior moment?
