Hi folks We were arguing about insertion cycles of various connectors at lunch (something engineers do) so I asked the great god google: Since the Tesla Y came with a portable 32A 240Vac charge controller (ordered the nema 14/50 plug), could just use it as others do for charging. Looking at Wikipedia UL498 insertion cycles for Nema flat blade connectors , they show 250 cycles at 200% rated current. The J1772 shows 10K cycles but turns off so is disconnected no load. I don’t see the 14/50 no load insertion number, apparently UL 498 doesn’t test for that. Do to the reduced insertion rating of the Nema flat blade (in this case) 14/50 connectors, probably best to put the portable EVSE under an enclosure to protect from the weather and leave it plugged in. My P3 Killowatt meter shows 2 watts of ghost load so negligible. Stay connected, Mark
