I've read through the installation guide for the new Wall Connector, and I just can't wrap my head around what the actual wiring would look like to utilize the power sharing feature.
Currently in my garage I have a 14-50 outlet that's connected to the main breaker panel outside with 6-2 NM wiring through my crawl space and a 50A breaker. If I were to remove the outlet and mount the Wall Connector over the J-box to hardwire it, I just don't see how you would then daisy chain the power along to a second Wall Connector. It doesn't seem like there would be room in the J-Box to pigtail 6AWG, nor does it seem like a smart idea to me (giant wire nuts???).
Is the only way to do this correctly to install a sub-panel in the garage using the existing wiring and breaker, and then run two 50A circuits from that sub-panel to each of the Wall Connector locations?
Another related question... I see that 6-2 NM can handle 55 amps, and as far as I can tell you're allowed to size up to a 60A breaker since 55A breakers aren't a standard size. In this case could I just size the breaker up to 60A with the existing wiring, and then safely Power Share two Wall Connectors from that circuit? It seems safe to me since the EVSEs should only ever be pulling 48A from the 60A circuit anyway, never exceeding the 55A rating of the 6-2 NM.
Thanks!
