I have an EVLink EV2430 wall charger. I got it about 10 years ago to charge a Nissan Leaf. I now have a Model Y which I purchased one month ago. The charger has a dryer plug 14-30P with nothing connected to the ground prong. It works flawlessly when plugged into my dryer outlet. A little inconvenient because I have to put the cord out the window and across a porch to the car that is backed up to the front of the house. i had an electrician put an 14-30R outlet in my garage. The wire is 10AWG with about a 130 foot run. It has no ground wire. The electrician said that was legal as it is connected directly to the main panel. The car charged fine twice but with a voltage drop of 8 volts compared to the dryer outlet (243V 30amp). Now the wall charger trips within a few minutes every time I try to charge. Even if I restrict the amperage to 15amps it will still trip. With the restricted amperage the car is saying the voltage is 243. Both circuits have an 30 amp breaker on them. Any suggestions would be greatly appreciated. Thanks so much.
