Re: [EVDL] 14/50 240V vs 6-50 (3 wire) receptacle for EV charge controllers

Mark, Modern EVSE do not use the Neutral, but early EVSE did for their control circuit power, because a 120V power supply was cheaper and easier to find than a 240V supply. Today all EVSE use a multi-voltage switch mode power supply, but just to illustrate: the first version of the Leaf

[EVDL] Why NEMA 14-50 instead of 6-50 for EV charging? RVs

Hi folks It looks like it was from the days when we had to plug our EVs into RV 14/50 sockets while on the road since that was the only 240Vac level 2 option at the time (although the neutral isn’t used for EV charging it certainly is for campers).

[EVDL] Ground presence (was: OT Solar Electrical Issues)

Tesla chargers are infamous for using too much current in their ground presence testing, so that they trip the 5mA GFCI units. This leads people to swap out their GFCIs for regular breakers, so this safety feature makes them less safe in the end. Ken

Re: [EVDL] Ground presence (was: OT Solar Electrical Issues)

Yep, I made sure to use well under 1mA for the ground presence detect to avoid upsetting upstream GFI. Same with the built-in GFI test, I made sure to *not* introduce any ground fault current externally for the internal test. I heard stories that some EV Charger designers made that mistake and had

[EVDL] 14/50 240V vs 6-50 (3 wire) receptacle for EV charge controllers

Hi folks Not to stir up another firestorm again - but I was curious why a 14/50 240V socket was chosen for portable EVSE charge controllers when they *don’t* use the neutral wire? The NEMA 6-50 sockets without a neutral would seem more appropriate but aren’t used that often and would need a
