My situation is more of a complete electrical re-do than just a 60 amp circuit install. My house was built in 1955 and only has 100 amp service. I've got no gas line to the house, everything runs off of electricity. I've got geothermal for my HVAC which luckily is very efficient, but there's no way I would be able to charge a Model 3 while I've got the HVAC running at full blast plus a few other large appliances running. Currently waiting on permit approval from the town (they're 4 weeks behind on approvals...) so my electrician can start work. Upgrading to 200 amp service and getting an entirely new breaker box to replace a main panel and sub panel in addition to a 60 amp circuit for my HWPC in the garage. For whatever reason my current breaker box is located 20 feet away from where the main comes into the house, so local electrical code dictates I need a master shut off outside where the main comes in. Basically several out of ordinary things with the construction of my house that are bringing up the cost of this electrical upgrade. Got three different quotes. I'm going with the guy that's charging $3600 and was by far the most professional of the bunch. The most expensive quote I got was $6600. I just laughed when I saw that guys quote.
