![]() ![]() Tesla owner's garage fire highlights EV charging safety and cost. My point is, it will raise serious home insurance related questions. For example, the home insurance provider will ask if this Wall Connector was installed by a licensed electrician or no. There may be many risks associated with this and if something happens to the installer or the house the insurance is going to ask though questions. They wary from city to city and from state to state. Check your city's electric ordinances first. Dazzford posted this picture, used here and another picture on Imgur.ĭon't try it yourself, unless you are a licensed electrician or have consulted one. Since his Wall Connector is outside, he also added a small rain guard over the top of it to protect it from rain. Various left over cedar wood I had laying around.240 ft of 4 AWG THHN stranded copper (I could have done 160 ft of 3 AWG and 80 of 4 AWG for the ground if I wanted to do 100 amp).Very easy to do, and I'm completely to code apart from the licensed electrician part," he writes. It took me about 8 hours total split across the weekend to do everything. "It cost me less than $260 in materials (not including the wall adapter) for a 90 amp circuit, running 60ft through my garage in sch 40 PVC conduit. The Wall Connector for fast charging cost him ten times less than he was quoted for and only eight hours of work. He says when the quotes came back around 3,000 dollars, he decided to go for it different way. I have plenty of experience wiring outlets, installing new breakers, and reading code to make sure things are done safely," writes Reddit user Dazzford. I cant even do the work and then have it inspected. This is why your main panel can have 3 wires going into it but any sub panels should have neutral and ground separated and not bonded.Īnyhow doesn't matter since your current wiring is fine, just didn't want you making a mistake I may have made myself in the past before researching."I live within 50 miles of NYC and my locality has a silly ordinance that all electrical work, no matter how simple, must be done by a licensed electrician. Even if you fake it on the plug it will work and test correctly but you can get backfeed through the plug so possibly one random day when for some reason everything decided to use 1 of the 2 phases on your 200A service you might have 100A going through your plug that joined the 2 and maybe choose the shower to ground some of it. Those 2 wires serve different purposes and you don't want to create a loop. You are right that ground and neutral are joined at the panel BUT THAT IS THE ONLY PLACE THEY SHOULD BE JOINED. Since other have basically said that I wasn't going to post except you said:įYI, this is on the main panel, where I have learnt Ground and Neutral is the same, so perhaps is it OK to install a 4 prong outlet with just 3 wires? I actually cut my neutral pin off the Tesla EVSE to work on a 14-60 so it will work in any 14-XX but I have to set my limit if I plug into a 14-30. I know it isn't up to code but I plan to do the same thing but maybe plug up the neutral too just so I don't need 6-50 to 14-50 adapter (and I already use 14-60 other places). IMO label that 14-50 saying there is no neutral. If you wanted L1 support you would need the neutral. The electrician is right, 6-2 w/ground is all you need for L2. Is this the correct install method? Can a 4 prong dryer outlet be installed with this wire? Can a 4th ground wire be added to the 220V dryer style outlet, and connected to the ground wire from a nearby 110V outlet? FYI, this is on the main panel, where I have learnt Ground and Neutral is the same, so perhaps is it OK to install a 4 prong outlet with just 3 wires? Worst case, I know I will have to redo the install (professionally), but wanted to check here what the typical install should be like.įYI, this is on a 60A dual pole breaker, with a metal guard installed over it.Īlso FYI, this is in the Pittsburgh, PA area. When I asked them about this, they claimed the Wall Connector only needs 2 wires + ground, so they use this. ![]() However, I see now that they installed "NM-B 600V 6/2 wire with Ground". My fault for assuming they would run a 4 wire cable. Landlord agreed, as long as I got it done professionally, and that I would install a 4 prong dryer style plug when I eventually move and take the Wall Connector with me.įound a company on the Tesla site that does these installs, they quoted same price for installing 4 prong dryer style outlet as for for wall connector. Tenant here, got a Tesla few months ago, and asked Landlord if I could install 220V outlet in garage at my exepense for the wall connector. ![]()
