hi, im working on democrotizing ev charging, idea is anyone can plug in an evse to charge an ev by default. I want to use the tesla J3400 socket rated for 300 amps air cooled. I want the full 200 amps avalible if user buys such evse or small and cheap 32 amps evse. Plan is to feed total transformer load through signal pins using a ct and basically change ct ratio for transformer kva to keep a standard output for 100% load. I designed a phyical lock that enforces make and break at zero current and touch safe. My question is about NEC code and equipment grounding conductor (EGC). An evse enforces a 20ma max current on PE pin, given i dont have gfci that would mean i have to carry load fault current on PE contact thats rated for 80 amps contentious.
My question is can i use "outside feeder tap" rule (NEC 240.21(B)(5)) to get 200 amps?
