GFI tester - November 2016

Post by KeepItSimpleStupid » Tue Nov 01, 2016 5:44 pm

You can buy them. You can make them. What is the normal trip level,you'd have to look up. A resistor (suggest metal oxide) from ground to hot, at about 6 mA should trip the GFCI. e.g. R<=120/0.006 The problem is more complex when you look here: ... ba57a.html

I actually suspect that you may have an AFCI/GFCI combination and it's tripping on an arc fault because of the motor. If that's the case, I would consider an RFI filter (possibly medical grade which has a lower leakage) and appropriately sized ZNR's.

There have been reports of just plain flakey GFCI's. So contact the manufacturer too.
