i just completed my HPWC installation today but before inspection I have a few questions.
I had an electrician run a new 100 amp line from my main 200 amp service into a new sub panel that I provided and installed in my basement.
I then ran 6/3 romex with ground from a new 50amp breaker on the new panel up to my attached garage and made entry through the basement ceiling into the attached and finished garage wall. I had to bend the romex to make rear entry into the HPWC this did not appear to be avoidable and it is against code in my area as far as I know to run NM-B inside of a conduit junction.
Neutral was terminated at the panel for possible future use and the neutral wire was capped at the HPWC.
My only two concerns at this point are
1. The limited space inside the HPWC to terminate the cables forcing a short bend radius for the individual conductors. Does the inspector expect the sealing plate to be removed at inspection? I closed it up to keep my kid out of it.
2. With the mounting bracket for rear cable entry and with this being old work it did not seem feasible to provide a junction box behind the HPWC. Is this ever required? The wall bracket is attached to stud on one side and I installed high strength toggle anchors with shovel head machine screws to make sure the charger seated into the bracket properly.
My only comment about the install difficulty is that the terminals on the HPWC are a real nightmare to work with. If I had been told it would take nearly an hour to connect the terminals I would have laughed, but it did. I also didn’t see where Tesla provided a torque rating on the connectors. Should I torque them to the same 35 in/lb that my breaker required for #6 CU conductors?
I guess that was four questions.
