It is possible that only short duty cycles with long off times for the lift motors may have allowed them to remain operational.
I can imagine some procurement droid getting a call from the lift vendor with a today-only ‘fast-track $63 discount’ for substituting 1ø motors, and, by the way, when they’re unloading them the delivery guy can hook up two wires for an extra $700.
I would do careful meg checks to be sure the new equipment doesn’t have any fried insulation. Also check for potentially damaged capacitors in the 1ø motors and signs of overheating in any magnetic-starter coils.
Keep track of costs for fixing the screwup and let a the right procurement manager know how much his hot-shot buyer “saved” the company using a slimeball vendor with unacceptably substituted equipment.
Of course, this situation and suggested responses are completely hypothetical. Nothing remotely similar ever happened to me. ;-)
