For a hardwired EVSE, wouldn't the "continuous load" and the "calculated load" be the same thing? That is, the 60A breaker supports maximum 48A of "continuous load," so you wouldn't use an EVSE which could pull more than 48A. So its Calculated Load would also be 48A or less.wwhitney wrote:protect it with a 60A breaker, provided that the calculated load is 55A or less.
Calculated load and continuous load could definitely be different if the breaker served a receptacle which may have intermittent loads above 80% of breaker rating (e.g. arc welder).
