This guide is serial communications directly to the controller. These RAPI commands will never go away. The WiFi guide referencing USER RAPI refers to RAPI over the WiFi HTTP interface not serial level RAPI.
Earth Ground testing verifies the ground path included the earth rod, electrical panel, circuit, socket/plug to the station. This is done by intensionally passing a very small current from each hot to ground.
It is possible to get a false positive if the relay is not operating property failing to close on command.
The 4 corner holes are 3 7/8” x 9 1/4”, center-line holes a 9 1/4.
The center holes can be used for static mount by either tightening the screws down so the station can not slide to release or using a screw with a larger head than the release opening.
Cables from OpenEVSE come factory terminated with sleeve ferrules. The wording was changed, “should” is now “must” and we made sure it was clear in both EV cable and input cables require ferrules.
The thicker wire is one of the three red wires with 1/4 QC terminals pre-crimped. The thin wire goes to the UBEC power supply for WiFi. The ring terminal can be used at the end of the UBEC red wire.
None of the AC connections are polarity sensitive. AC_Test are identical circuits. Just ensure the AC_Line wires connect to the AC Input and AC_Test connects to the load side of the relay.
I personally build with black wires across the bottom of the relay and reds across the top. Same on the board connector blocks black wires on the bottom red above. But again neither is polarity sensitive.
Soldering is an alternative. It is not our recommendation, but if done well works fine.
The Packard C240C is rated 50A for resistive loads. EV charging is resistive. 40A is the rating for capacitive loads such as AC motors.

Yes, it looks like a contributor accidentally removed step 5. We have reverted to the version prior to the edits.
The picture is 3 wire hot hot ground. The white wire had 1 inch or red shrink wrap to indicate it is hot 2.
