Contactor struggles to close?
Posted: Wed Feb 06, 2019 6:40 pm
Yesterday I was greeted by a loud rumble as if the contactor inside the EVSE was trying to close but there wasn't enough current to do hold it so it was sort of vibrating, that's my interpretation of the sound anyway. The charge finally started after a second or two and there was no such "effect" a subsequent plug-in. I think I may have heard it happen once before but not entirely positive. Anyone experienced anything like it?
