Wiringng A Tesla Pedestal Charger

After wiring (see below).

We landscaped around the new Tesla pedestal charger here with gorgeous topsoil, grass seed and flagstones along the driveway. The tall rhododendrun behind it acts like an umbrella while blending it into it's new home.

We installed it on a 60 amp breaker on the house panel. The charger itself draws a maximum current of 48 amps. This charges the car much faster than the typical 15 amp circuit you can plug into on a regular outlet. It takes about 8 hours to charge the car from a low battery with this fast charger versus over 24 hours with a normal outlet!

The wire we used was a mix of 4 and 6 gauge THHN THWN wire that's rated for underground burial and wet conditions. The thicker 4 gauge wire carries the 2 hot wires (black and red) and the thinner 6 gauge (green) was used for the ground wire. We bought 80 feet of each color and used most of it, and had about 8 or so feet leftover of each.

Since the 42' route we wanted to run the line through was not totally straight, PVC ended up being the way to go. Schedule 60 PVC is what we went with - schedule 80 is thicker but not as easy to find or widely used nowadays.

It was an effort to run the cable bundle through 1.25" pipe and we routed it tightly to the circuit breaker through a number of conduit bodies. These are the 90 degree bend boxes you can use to pull cables through tight corners, most notably seen in the 90 degree bend into the breaker box for the terminal connection.
