Sometime back I wired from the 003 into a box mounted onto the frame of my scroll saw, which wants 6a per leg. At the 003 load terminals L0=green, L1=white, L2=black, L3=red. Cord wiring from the genset is into a slow HACR 10-a breaker, out the breaker to the SqD start switch, back down to the saw motor via a female receptacle in the box and a male plug and pigtail to the motor. About the time I started wiring I learned that my multimeter had bought the farm, so no continuity checks. Believing that I had everything correct, I set the selector to 3-phase and fired up the 003. Hit start on the saw...silence.
On re-visiting the saw, I note that I when I wired to the breaker and switch the wires are, consistently from left to right red>black>white. Into the female receptacle rear they are W=white, X=black, and Y=red. The male plug wires match up with the receptacle wires. At the motor I connected L1 to 1 and 7, L2 to 2 and 8, and L3 to 3 and 9; 4,5, and 6 in the motor are bunched...standard low-voltage wye. I will re-verify the motor, plug, and receptacle wiring after I finish this epistle.
Had an electrician out today to wire a couple of ceiling fans. When we finished the fans I turned the selector switch to 3-ph and started the 003 and had him put his meter to work. Checking the legs on the onboard genset meter, each read ~210V. We measured at the load terminals and saw ~112V between L3-L0, ~51.5V L2-L0, and ~98V L1-L0. At the saw these same values were observed into and out of the breaker and into the switch. Nothing was coming out of the switch. This is good, in that I know to repair/replace the switch.
The voltages, however, were more than puzzling. Shut the genset down, changed the selector from 120V 208V 3 PH [9 o'clock position] to split phase [3 o'clock position] and re-started. In that position the legs at the split bolts, breaker and switch were something like 195V, 175V and 175V, while the onboard meter read L3-L1 240V, L3-L0 120V! The '91 generator underwent a tier-2 re-set in '07 and had about 11 hours on it when I won it. I have used the convenience outlets a bit for single-phase 120 on several occasions without issues.
Might the varying leg voltages suggest a VR issue? I have no clue as to the selector switch, other than perhaps incorrect attachment at re-set, but then, the onboard meter matches the switch settings. Anyone have any thoughts? Since I just learned the above about an hour ago, I thought I'd post first, then start going through the TMs.
Later,
