So I've had 2 electricians out to provide estimates for installing a NEMA 14-50 receptacle .on a dedicated 240 volt / 50A circuit. The first came from the Tesla recommended list. The second is a well-regarded company. The Tesla-recommended electrician gave me the full spiel about having to do a load calculation, pull permits. send a report to Tesla post-job, etc. Then he checked that we had 200A service to the house (and not 125A as he 1st thought), and then proceeded to take pics of the specs for all the big appliances in the house so that he could perform a load calculation. He even went down to the crawl space to check the access. Total visit well 30-45minutes. He said his estimate will be to me by week's end. The second guy was very familiar with what I needed, even mentioned doing work at the local Tesla office. He took a look at the garage, the electrical panel in the garage, then around the side of the house and was done. His $520 estimate was emailed to me a little less than 15 minutes after he'd arrived! Both had 5-year warranties on the work. Which style was your experience closer to? Also, have you heard of a report going to Tesla afterwards? I'm hoping the Tesla-recommend guy's proposal is similar in that he won't recommend another 100A of service to be done. Then that'll make it hard.
