Took delivery of my Launch Edition Black/Black a week ago and I am having a terrific time with my 10 year old grandson ( who is the official expert on Rivian).... he has read the entire manual._I have tried to get my wall charger installed efficiently on a pedestal just outside of one of my garages. I started the process with Rivians vendor QMerit. The quoted $4200 to install a 60 amp breaker ( in a 200 amp panel that already exists) and about 25 feet of 4A wire. Seems like a bit of a press by their subcontractor. I am located just outside of Dallas and I believe I am the first Rivian in Rockwall County so no one has any experience installing this particular wall charger. There are lots of Tesla's so it cannot be much different. Can anyone tell me what they were charged for a similar install so I might estimate what is fair.
Someone will need to do an inflation adjustment calculator, back in 2016 I paid $1000 to run about 150' with a 100A breaker in the main panel, install a new 100A sub panel in the garage, install a 60A breaker in the new sub panel, run ~30' of conduit from new sub panel to my Tesla HPWC. That included the cost of permits.
Several months later I decided to install my own NEMA-14-50 to the panel. It cost me less than $100. I then called the electrician up and asked how much to check my work and get permits - $150. I asked him how much to add a HPWC? $350. So it was a $500 total to install the 2nd HPWC, check my work on the NEMA 14-50 and get permits to cover both. Much less than I was expecting. He would've charged me $250 to install the NEMA 14-50 if I hadn't done it myself.
That said, I believe the cost of cable/materials has increased at least 3x since I had mine installed, but you're also only running 25 feet.
