All of the commercial / light industrial places I've been to had 208/120
Y service. Only seen 240 delta in heavy industrial settings. Based on
some 5 yrs of CNC service in the northeast.

I have 440 delta and 240 single phase in my garage, delivered from the
mains.

Lucky you. Not much need for 440 and the more expensive switchgear to go
with it unless you have a really big installation.
