Todays visit was a for a quote for a tesla level 2 car charger. We took a look at the panel and found that it was fully filled and had no extra slots. They had power to an incorrectly wired sub panel in the shed because it was only 120v. We did a load calculation and found we can add an 80amp sub panel in replacement of the wrongly wired one in the shed. We then would run power from there down the hill to the driveway for the car charger. We would also need to install posts to protect the car charger.
