This guide provides the assembly procedure for SAE J1772 cable from parts available from at OpenEVSE.
-
-
-
This guide uses 40A EVJT cable available from OpenEVSE.
-
Remove 3.25 inches of the outer jacket.
-

-
Strip and retain insulation from Purple wire 3/8 inch (0.375")
-
Cut orange wire flush with outer jacket.
-
-
-
Slide gland onto the cable. The notched end should face toward the stripped conductors.
-

I'm looking for assistance replacing the 120v outlet plug that broke on my charger. It has green,. White, red, orange, and black wires. I'm assuming some Double up on both the the positive and negative terminals of the nema 6, 120v plug. If possible could you tell me which wires go on which terminals. Thank You
Will this work on Chargepoint Flex Home charger? I looked at the pinouts of this versus the one I currently have and Chargepoint has all 5 cables used.
If you can’t get the Plug here - it is on Amazon B08XWD2XHX
I didn’t have the crimp tool - my Weller Soldering Iron was OK for the small terminals, but no way was that going to get the large terminals done.
But I do have a spot welder - and that was perfect to instantly heat the terminal - each #8 wire was pre-tinned using the Weller - which then made a tight fit in the terminal
When I clamp it with the spot welder across the barrel - more solder at the ready - toggle the welder and the barrel quickly hits temp - add fresh solder at the wire joint - spritz with water spray to cool.
O-Rings never got toasty - perfect fit.
