Tesla wall charger enclosure for mountain weather


2021 Tesla Model Y LR AWD
Mar 13, 2021
Sacramento, CA
I jumped through all the HOA hoops to install a wall charger at my parking space in a community of free-standing condominiums at 7,000 feet on the Nevada side of Lake Tahoe. The homeowners association provided strict specifications for size and color: 18" wide, 14" deep, 48" high and Oxford brown.

I tried to find a fabricator to build a steel box similar to the nearby "bear box" garbage enclosures but the quotes were ridiculous. So I built an enclosure from a single sheet of 3/4" plywood mounted on a two-foot-square concrete slab. I'm surprised there aren't more commercially available enclosures.

Pro tip: Beware of Tesla- recommended electricians. One guy I contacted wanted $3,500 to replace the 50-year-old electric panel and then an extra $1,000 to connect the wall charger, even after I told him I was running the conduit and pulling the wires myself. I call it a "Tesla tax."

I bought my own panel and breakers at Home Depot for about $600 and found a respected electrician in Reno who swapped out the panel for $1,200. By the way, while I was pulling the #4 AWG wires for the wall charger, I also pulled a set of #6 AWG wires for a 240v NEMA 14-50 outlet on a GFCI breaker for future visitors with non-Tesla EVs– and, of course, a 120v circuit for a light and outlet for vacuums, etc. One more thing: If you're running underground conduit, pay a bit extra for 2" PVC. Plastic is cheap and it makes pulling heavy conductors a piece of cake.
