Hope you meant "hot and hot". ;-) The HPWC does not use the Neutral.
Glad you got it worked out! I did 6 AWG and that was difficult enough.
Thanks! Yeah. Should have said that.
I learned a some key things while doing this that might be beneficial to others, and will definitely be beneficial to me, as I have to wire up another, almost identical setup at my stepdaughter's house for her boyfriend's new Model 3:
- The terminals are plenty large enough to accommodate 4 awg wire. I was really concerned that it would be tight after looking at only pictures. As GWord said earlier, these terminals look like they'll accommodate even 2 awg wire (I pity the person doing that work...).
- I have discovered that it seems really difficult to keep the terminals in the "open" position when the charger is mounted on the wall. Gravity is not your friend. I found the terminals stay open for insertion much better if the charger is upside down. Not sure how this would work for some installations, but when I install the one for my stepdaughter's boyfriend I am going to terminate the wires in the charger before I even run the wire into the wall and terminate to the breaker panel. This will work for me because the wire will only need to be about 3 feet. But you should consider terminating the wires prior to mounting the charger, if practical for your installation.
- There are two rear entry holes in the charger base for routing wires. The low profile bracket has a cutout for the top, smaller one, and it seems logical to use it, since it's closer to the terminals. However, I would recommend using the lower, larger hole. This will give you more room to maneuver the wires inside the charger.
- If you have some spare 4 awg wire (only about 6-8 inches necessary) I would consider cutting a short piece, and using a single lead as a "test" piece for the bend. Bend and shape it until you have a piece that fits into the terminal nicely coming in from the rear. Then use that as a template to pre-bend the actual wires that you will be terminating, prior to routing them into the charger. This should make it much easier, since it is difficult to maneuver heavy enough pliers to bend the wires inside of the charger.
I hope this helps anyone who is planning to wire their own charger.
