        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
