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?

Delta or Wye on the generator, will affect the voltage it can develop.

I disagree that you can't connect a Wye load to a Delta source. Why
not?
The Wye Load will still consume power, even if the center neutral is
not connected.




You can connect a delta to a Y load if the legs of the load are balanced
as in Iggy's case. If the loads are unbalancd you will have unbalanced
voltages in the legs and if the unbalance is large you will probably do
damage because of excess voltage in one of the legs.

Another thing about generators I found out....

I was initially skeptical that is was possible to get single phase
from a three phase generator since there HAD to be three pole sets...
Then DOOOHHHH ! you can re-group the twelve coils sets into four
groups of three, for single phase, or three groups of four for three
phase.

Hopefully that gives a few ideas...
