Thanks for your thoughts/input.
The short response from the electrician that finally installed the circuit is that given my house setup (A/C, electric oven/range, normal small appliances, LED lights) I would never pull the 100a my box is rated for. The 50a circuit for the car would be okay.
I know now about the NEC formula but I'm assuming that given the electrician's experience he was well aware what that formula would yield. The circuit has been working fine. I charge in the middle of the night (ComEd hourly pricing generally $0.015 - $0.02 /kW - sometime negative so they pay me! - drawing 8kW during charge) and wake up to a fully-charged car. I was very pleased with the quality of the installation - would recommend him to anyone in south/west Chicago area.
Nice!
That is an amazing non peak usage rate! What is it during peak time?
It is crazy the different rates in different parts of the country. I was blown away by a recent thread on power costs in San Diego.
