Wall Connector - max run for 6/2 Romex on 50A breaker

[sethinGR]

The manufacturers of EVSEs know that 55A circuits don't really exist, so they will only build them with configurations for either 50 or 60.

And you are correct, I verified with a Juicebox user, the app only has the standard ratings 48, 40, 32, etc. Thanks for all the typing to clarify that. I guess I am stuck with 40A.

1. Code says 6 GA NM-B circuit is allowed to be used with a 60A breaker. I don't have the exact NEC section, but that is what he (and others) have told me.

NEC 240.4(B) (with reference to the fact that 55A is not a standard sized circuit breaker as listed in 240.6)

I don't think you will be able to find any EVSE sold by any company that can be actually permanently configured for a maximum 44A continuous, as if it were on a 55A rated circuit.

I finally got my back-ordered since May JuiceBox 48A, and hooked it up and configured it and lo-and-behold I can set it to 44A. I set it that way on the Device Configuration screen, so I think it is as permanent as it can be for a piece of electronics. I will drop a message here if for some reason it switches to 48A.

Wow, that is really interesting. I don't think I've seen one before that would let you set such an unusual max value. And it does show that as the actual limit, since it's 44/44.
