I wonder if LCM has ever measured the power draw of each of their big machines?

We tried to get a 370/145 running at a guy's
house. That had the 17 KVA motor generator set in the back (WAY more than
a 145 needed, but they apparently used one MG set for a range of machines). But, he only
had 60 A 240V single-phase
service, and we couldn't even spin up the MG set with no load. We built a static
phase converter, but the imaginary
current was over 60 A. Well, NO SURPRISE, if we'd just read the nameplate we would
have known it was a fool's errand.
The 3-phase line current on the thing was about 55 A, per 3-PHASE LINE, so running it off
SINGLE-PHASE, the line current
would HAVE to be 1.7 X that much, wouldn't it? OF course!
