The campground owner was clueless as to how two phase power worked. Each leg of a 50 amp service is 180 degrees out of phase with each other. Voltage between either leg and the neutral is 120 volts but voltage between the legs is 240 volts. That is why an open neutral can cause serious damage to appliances in your RV and must be corrected.

I am referring to my watchdog as my EMS, but it is hardwired in my coach. It is the first thing my incoming power reaches (just as if it was connected to the pedestal). I have checked connections on watchdog and everything seems solid. As mentioned I have checked the cord and pedestal and they check ok. Due to the randomness of the errors code I guess I can’t rule out sporadic burp in the outlet. I am going to a state park up the road next week to just try it out on a different pedestal to see if that makes a difference. Nothing I do in the rv seems to effect the error, ie run everything, nothing, or something in between. It’s been plugged in for 24 hours now without the error but nothing is different than before. I did shoot every line and connection with my temp gun and didn’t find anything getting hot. If the issue continues at the other pedestal I will shift my attention to the watchdog. It has a replaceable card on the inside. Thanks for all the help.
