No water anywhere near where they were. They commonly get used as the first outlet in a daisy chain of outlets, mainly outside, hence the need to get the line and load correct. This makes every outlet down stream gfci protected...and all the problems that come with it. Usually it's outdoor Christmas lights and cords etc that are nowhere near the gfci outlet.

Like a moron I didnt read it , I just wired it as the old one was. Working now. I did the same thing. After the second one didn’t work, I finally read the instructions. 1 Quote Link to comment Share on other sites More sharing options...

Ill run into it a lot at work. Have a controller not getting juice and have to find the gfi outlet on that circut and reset em . Quote Link to comment Share on other sites More sharing options...

Yes. Are they necessary in a lot of the places they’re mandated now? I dunno They measure the difference between current on the hot and neutral. They are extremely safe and can be very reliable but they gfci outlets have a fairly small service life and that is annoying. I believe they trip at under 2 mA of differential. That will save a life every time. The annoying thing is some single phase motors will trip them out every time. I used to think it was the introduction of a starting capacitor in the circuit but I spoke to an engineer about it and he said that wasn’t it and that some motors start to deteriorate slightly they can be problematic with a gfci. He said it was an issue with the motor and not a design element. They absolutely will not work with vfd controlled appliances like some new refrigerators and such.

toslow Posted November 12, 2023 Share Posted November 12, 2023 Maybe burnt fuse can chime in and give some advice on this matter? 1 Quote Link to comment Share on other sites More sharing options...

Well it’s sort of an issue with the motor but also an issue with the element in the sense that single phase motors can run a long time with slight issues but the gfci says nope and won’t let it run also seems like long extension cords cause them grief too Quote Link to comment Share on other sites More sharing options...

Haven't had any issues with my pond pumps and single phase GFIs. Also only used vfds on GFIs in 3-phase installations ie tank farms, no issues.

Like my thermregulated heat line, but that was understood up front. Quote Link to comment Share on other sites More sharing options...

Seems like DC motors and controllers would be a better solution for new appliances instead of VFDs. Neal Quote Link to comment Share on other sites More sharing options...

Prob the worst is the new digital battery chargers that won’t charge a battery unless it’s already charged man I hate those things Quote Link to comment Share on other sites More sharing options...
