But again, I will do some testing to verify. Standing by...Re: GFCI at shore power trippingSo here in Bellingham we just got an out of the blue cold snap and snow and I don't want to put water in my hot water tank to start my testing/pinpointing until it gets a few degrees warmer. That being said, when I went to drain the tank by removing the anode rod, I noticed that the trip button on the tank has been tripped. That tells me it is an issue within that hot water tank circuit. I also installed a 12 gauge extension cord and dogbone electrical adapter that will be better suited than what I had. Just wanted to keep folks in the loop. So until some warmer weather comes, we are in a holding pattern.Re: GFCI at shore power trippingI will definitely check the existing power cord. Thanks!!Re: GFCI at shore power trippingFound my multi meter. There is no continuity between the pins on the shore power cord (disconnected from house and adapter removed) as well as I tested the adapter and there is no continuity there either. That being said, I just discovered that the extension cord from shore power is a 14 gauge extension cord. From my knowledge, I should be using a 12 or 10 gauge. Don't know if that is the issue but it needs to be corrected anyway. I am going to get a new cord and dog bone style adapter and then continue trying to isolate. If I am unable to pinpoint the issue at that point, I am going to take it in for servicing. I will keep you posted. Thanks for everyone's help!Re: GFCI at shore power trippingErg. I mean converter. I should have waited a little bit after breakfast to post this. Sorry for the confusion. The converter is a WFCO 55 AMP, model # WF8955PECB. Everyone on here has given me plenty to look in to so I will do some poking around today. I do have a multimeter.Re: GFCI at shore power trippingOops. I meant 120 volts. Not enough coffee yet. :) I will try a dogbone style adapter.Re: GFCI at shore power trippingAlso, I did plug it into another power source at home and it tripped that GFCI too.Re: GFCI at shore power trippingI do happen to have another known good adapter so I will try that as well. Thanks for the suggestions!!Re: GFCI at shore power trippingIt is a 30 amp RV. The adapter plug is 30 amp to 15 amp adapter. The trailer is parked at my house and I keep it plugged in while not in use in case we want to use the lights or radio in the trailer when working on the trailer. I will try and do some testing today once I find my multimeter and get back to you guys. Thanks for the input.Re: GFCI at shore power trippingThanks for the reply! You have a good point there but the connections at the adapter and at the plug in source are out of the way of moisture. It has rained a bunch here the last couple months and haven't had an issue previous to the water heater element failure.
