Just for the kicks, I wanted to make a 60 kw load bank to test the
generator.

I have three 20 kW electric heat strip elements.

I wanted to connect them in a delta connection. This way, as I
believe, I can get 60 kW out of the three phase generator (except that
it is not capable of making 240v, only about 216, so it will be a
little less than 60 kW). With a single phase connection (for my home
generator), using only two terminals out of three, I would get 20 kW.

Am I missing anything here? For a three phase connection, does it
matter if the generator is wye or delta wound?
