I've read this entire thread, and am impressed with the braintrust here. May I tap into it? An electrically-savvy buddy and I are installing a Wall Charger v2. The car is a MS with the 72a charger upgrade. Tesla says the WC needs a 90a breaker, which we have installed in a 200a main panel. The load calcs even with a 100a breaker show there is plenty of capacity to service concurrent loads throughout the house with the additional breaker. We have run 4AWG and 6AWG for the ground through 1" rigid EMC from the panel across the garage ceiling and down into the top of the WC mount, connecting them to the block inside (pics below). Total run is about 15'. All good so far, I think. As others have discovered, there are odd inconsistencies and omissions in the manual. We're about to attach the WC guts to the mount and before i power it up I want to make sure of a couple of things. The 4AWG pigtails connect to the green block, of course. The ground pigtail surely must connect to the aluminum block on the PCB (see pics), but the manual is silent on this. The rotary current dial is set to "C", which is the setting for 72a of output. An inconsistency on the DIP switch: the manual says about position 1 that UP is for "Line to Neutral (277v) and DOWN is "Line to Line (240v)", yet the sticker on cover panel (pic) says UP is "Line to Neutral (220V)" and DOWN is "Line to Line (240v)". The unit shipped with position 1 UP. I apologize for being dense, but shouldn't it be DOWN "Line to Line (240v)" for US residential service? Thanks for your input on this, or anything we screwed up!
