Well, I had a friend who bought a pair of 370/145's and had 
them in his house.
He wanted to get one running, but only had 60 A 240 V 
service.  We tried, HARD,
to build a phase converter to run the 17 KVA MG set.  IBM 
apparently used the
same MG set for a range of 370 models, and the one on the 
145 was VERY
oversized.  The DC load of the CPU was pretty much 290 A at 
4.5 V, or about
1.5 KW.  The idling current of the MG set was totally 
insane, even with a
phase correcting capacitor bank it was still over the rating 
of the whole
