Awl--
Got a 10 hp Baldor up and running--someone had misread the numbering on the wires, and thus miswired the motor--blowing fuses like crazy.
Inyway, I amprobed it, and a 5 hp Magnatek. Would you believe the 5 hp Magnatek, no load, draws substantially more current than the Baldor??? About 20-30% more. wow.... I don't know if that's because the Mag is really piggy, the Baldor super-efficient, or both.
The Mag, however, seems to have better bearings, as it spins quite a bit longer w/o power.
Also noticed wide variations in the current draw of each leg (both motors). For example, I read 3A on one leg, 9A on the other, 12 A on the third, operating off an rpc. Is that normal? In NYC-supplied 3 ph, I seem to remember identical current draws on each leg of a 3 ph motor (208 V).
