Stan:
A minimum of a 30 amp 240 VAC line would be a good
start. If you
continue with coiling you will eventually go for a bigger line.

At full rated load your close. However, in Tesla service you
will be
dealing with peak currents that will be a bit harder to determine on a
mormal budget.

The intermittant duty cycle will allow you to pull 10 KVA for
brief
periods

I just put in a 100 amp line to the garage, no lab here! If
you're
putting in a new one, bigger is better.

Have fun with the project
