New 20A GE GFCI Tripping

i have seen electricians, and other professionals make mistakes. why not call him back to rethink the set up?

 

I wonder why the manual says to plug it into a GFCI protected circuit when the EVSE has GFCI built in? I wonder why a L2 EVSE does not require a GFCI protected circuit? Ironic, isn't it?

 

No, it makes perfect sense. The only portion of the EVSE protected by its own GFCI is that which is down-stream of the CCID (the little box in the cord). The up-stream portion, including the plug, is not protected by that device. It's good practice for the entire thing to be protected.

A hard-wired device doesn't have a plug, thus the entire accessible portion is protected by the CCID.

 

What about a plug-in 240V charger? The electrician who put in the 240V wiring and 50A plug for my Chargepoint charger did not mention anything about GFCI.

 

My L2 EVSE is plug in. The outlet I had wired in the garage is not GFCI protected; nor it is required by code. Code does require 120 v garage circuits to be GFCI protected though.

I insisted all the outside outlets be GFI protected. The electrician used a GFI breaker for the 240v circuit, and a GFI outlet for the 120v circuit.
