UTS10BI trips GFCI outlet from UPS

[Anonymous user]

I just recently installed my new UTS10 but I'm having an issue with the UPS outlet. I've wired a GFCI outlet to my PROSINE 2.5 that charges and inverts power from several marine batteries (basically a better UPS). However everytime I plug the outlet into the front of the UTS10 it trips the breaker and continues to trip it when I reset the outlet with the reset switch. Any ideas? I've plugged other devices into the outlet and they do not trip the outlet. Should I not use a GFCI switch for the outlet and just use a standard outlet? Not a big deal but b/c it was in the garge thought it would be a better choice. Let me know if you all have any thoughts.

I've added two photos to clarify setup.

hmm, all i know is this: http://www.apc.com/site/support/index.cfm/faq/ -> search for FA158850 - i don't know if after reading this is similar to what you are seeing?

Thanks for the link. The GFI used wasn't the high end or well calibrated type I'm sure and may be the cause for the issues seen. I have to conclude after using an outlet tester that says the outlet is wired correctly and has no faults, all other equipment plugged into the outlet works as it should, and reading through your article that the outlet must be too sensitive for the UTS and some ground power leakage is occuring with the UTS that the GFCI detects and trips. I'll probably just wire a standard outlet to the prosine and see if that remedies the issue. If not then I'll probably call tech support and see if they have any ideas b/c the only other option is faulty wiring of the UTS plug for UPS power.


Thanks again for your help as usual!

The standard outlet worked fine and the UTS power light for the UPS is green 🙂 I used a weather resistant 20amp outlet which should provide a little more protection in the garage. I also used a gasket seal for the box but I hope no one decides to super soak my power distribution center. I think I'm going to simulate a power failure tonight and see how things go.

Thanks again for the help.
