"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. I cant even do the work and then have it inspected. I have plenty of experience wiring outlets, installing new breakers, and reading code to make sure things are done safely," writes Reddit user Dazzford.
He says when the quotes came back around 3,000 dollars, he decided to go for it different way. He decided to do it himself.
The Wall Connector for fast charging cost him ten times less than he was quoted for and only eight hours of work.
"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. It took me about 8 hours total split across the weekend to do everything. Very easy to do, and I'm completely to code; apart from the licensed electrician part," he writes.
This is a quick parts list he used.
- 50 ft conduit
- 3 elbows
- 1 4" deep junction box
- 2 90 degree pull boxes
- 20 conduit clamps
- 90 amp breaker
- 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)
- Various left over cedar wood I had laying around
Since his Wall Connector is outside, he also added a small rain guard over the top of it to protect it from rain. Dazzford posted this picture, used here and another picture on Imgur.
Do Not Do This Yourself
Don't try it yourself, unless you are a licensed electrician or have consulted one. Check your city's electric ordinances first. They wary from city to city and from state to state. 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. For example, the home insurance provider will ask if this Wall Connector was installed by a licensed electrician or no. My point is, it will raise serious home insurance related questions.
