Hi all, I replacing my dead Voltec charger with a portable charger (sorry, EVSE, I got chided last post for calling it a charger :roll: ) with a NEMA 10-30P plug at the end. I took off the Voltec and saw I had a red, black and green wire. I was expecting a red, black and white (hot, hot, neutral). Don't know if that's correct or if my licenced electrician just used the wrong color wire, but I checked the voltage with a multimeter and it comes up 120/120 out of each prong with the black probe on the green wire. Is this safe or do I need to have an electrician rewire with a hot. If that's the case I may opt for replacing the Voltec with another similar "hard wired" unit rather than hire a pro to install a neutral. Thanks!
