Updated guide - This guide positions the input cable on the left. However the station could be built with the input on the right if desired.
The seals compress to almost nothing to create a watertight seal, 5/8" is too long, the screws from the LCD coming down interfere with 5/8". Due to the binding/ interference a increasing the screw size would also require increasing the standoff size. This puts the LCD even farther away from the window and closer to main board.
The NEMA 14-50 plug is connected Hot 1, Hot 2 and Ground. For 120v you will need to build an adapter that is wired Hot 1, Hot 2, ground on the 14-50 (neutral is not connected) socket to Hot 1, Neutral, ground on the 120v plug.
OpenEVSE will automatically detect just one hot and set the current to 12A. L1 and L2 current is saved independently.
Twisting 2 - 12 AWG then folding in half gives you the equivalent of 4 - 12 AWG. The more area the better.
1/2" is the correct size. In order to get a water tight seal the gasket and washer are mean to be smushed. If you squeeze the pressure plate and alternate opposite corners you should be able to get about 2 1/2 turns and a great seal.
For a 4 Wire Setup, Neutral is not used and should be capped.
The copper electro plating process of the PCBs sometimes leaves more copper than desired. A little pressure while turning the screw should send them right through. Drilling should not be necessary.
Step 1 has been updated with the link to the source code and guide for loading the Module. In about a week I will have preloaded modules in the OpenEV store.
Pish button is to enter configuration menu, set timers, add xxx kWh, charge for xxx minutes, etc.
Unfortunately the pre_terminated leads which judt started shipping only come in 7". I will likely flip the positions on Input and J1772 in the photos which will give an inch more slack by sending the bottom connector to the far terminals.
