Help needed on PD9245 Converter

I am having a problem with a PD9245 converter. I replaced the old Univolt converter in a friends 84 Excella in June this year. Everything worked fine until a month ago when it PD9245 tripped the breaker, a GFCI, and kept on tripping it. I called Progressive Dynamics and told them what happened and they shipped a new unit to me. I installed the new unit last Monday and it worked fine until Saturday morning, when it tripped the breaker again and continued to trip it every time it was plugged in. I tried the converter on another non GFCI circuit and it works fine. Any idea what the problem is. The plug beside the converter is a GFCI plug, wired in with the exterior, bathroom and kitchen plug, as well as the end wall in the bedroom. I tried a plug in kettle on the GFCI breaker, and had a hand held hair dryer running at the same time and no problem. What can be the problem?? This one has me totally baffled!! Thank you for any and all help. Chris

Hi

Sounds like you have the ground and neutral swapped. If not that, something that is giving you leakage to ground.

Wiring in the trailer is original from factory. Breaker is wired correctly, I checked to make sure. Factory plug in/boxes are a sealed type and have not been changed. I did change the outside receptical, as it is a standard type.

You didn't tell us if the new converter trips other GFCI's as well. You only said you tried it on a non GFCI circuit. You may have 2 bad Converters.

Just found this:
OK so what does all of this mumbo jumbo have to do with the problem you are experiencing with your RV? Because GFCI devices trigger at current leakages above 5 milliamps they can cause problem for RVers that have switching type Power Converters in their RV's. These switching type power converters usually have built in input RFI (Radio Frequency Interference) suppression filters to keep high frequency energy off of incoming wiring. During normal operation of the power converter these RFI filters will exceed 5 milliamps of current leakage causing GFCI Devices to trip

There is only one GFI circuit in the trailer. That is the circuit breaker it is tripping, both the first and the replacement converter. On a non GFI breaker the coinverter runs normal and does not rtrip the breaker, as told in my first post. I am calling Progressive Dynamics in the morning. Chris

Have you tried replacing the GFI breaker? If it is as old as the trailer it probably needs to be replaced.
I don't see anything wrong with using a non GFI. breaker to power the converter.
GFI breakers are intended to provide a safe power source for outside receptacles and those near a water source such as sinks etc.

I am having a real hard time to find a replacement breaker up here in Canada. I did question about the breaker being old and tripping as I have had to replace other breakers of a different brand that have "worn out". Will search for a breaker again tomorrow. Thanks for the input. Chris

Hi

That was true a long time ago, but is pretty uncommon these days. Computers have the same sort of supplies in them. People got crazy when they would trip a circuit. The guys doing the filters adapted. They don't trip things anymore ...

More likely the bare copper ground wire that attaches to the PD9245 has developed a high resistance on the other end at the AS frame ground lug.
Remove, clean and reinstall.

I called PD this morning and they are waiting for my original converter to get back to check. Thank you Vich, for the idea of the ground wire corrosion. I never thought about the ground causing the problem. When I was talking to my friend this morning, she told me that she had a small fridge plugged into another one of the GFI outlets and it tripped the breaker as well. This was when the original converter was in the rig. Thank you for any and all help. Chris
