[GreenKeys] Model 15 Governor motor Specs RQ

[Ralph Mowery]

Because the gfci compares the power in the hot leg to the neutral leg if there is a large enough inductor in line the current can become unbalanced due to the current lag that a false trip can happen even though there is not an actual ground fault.

It’s been a while since I’ve had my 19 on, but occasionally it would trip the GFCI on the wall with a synchronous motor.  I’m trying to remember the exact circumstances, but I think it would happen when I'd switch on the 19.  I had always assumed that there was an initial surge of electricity getting the motor going, thus causing a brief grounding situation.  I’ve never been concerned enough to trace it down.

…but I also remember seem to remember that there may be a second hot wire that may be connected to the switched-on position on a 19.  Again, if I remember correctly, this second wire would have gone back to the table via the not-usually-seen four-prong plug — in order to power the rest of the table on a 19.  Usually these are taped off when using a three prong, but you might want to double check to see if this wire may be on a terminal it shouldn't be on or maybe even making contact with metal ground - if the tape has worn off.  Since a 15 and a 19 are pretty much almost the same, this could possibly be the case.
