Help with Equitech 1.5Q power conditioner

What is the amp rating on the GFI plug and the total amps you have connected to it?  That should answer your overloading question.  I would start by thoroughly inspecting all the power cables you have running in the system.  If there is a bad ground or possibly a wire has been damaged?  Replace one cable at a time and see if the problem persists, or the problem cable is isolated.  Just some things to try if you have not already.  Cheers. 

I have had a Son of Q for almost 20 years.   Never an issue .  I would suspect a bad GFI 

I believe it is an off the shelf Leviton unit.   It's probably pretty straightforward and any competent tech.   

As BigTwin suggested remove all power cords and then try them one at a time.  These are pretty simple inside so hopefully it's limited to the breaker.  

I had the same problem with my Q2 Equitech GFCI plug. I suggest you contact Equitech by phone with the issue and see what they suggest. In the end since I knew I was not over loading my unit I replaced the GFCI WITH A high quality standard outlet.

I am actually more than a little surprised that there even IS a GFCI outlet on a conditioner.  I'm not sure what the point of it is unless it's within 6' of a sink... :D

In any event, GFCI outlets are pretty standard.  If you know how to use a screwdriver you could replace it in less than 5 minutes, but I honestly have no idea what you would use it for.

Someone please explain.... :D
