Hello electrically smart fellow campers. You know me, I still don't fully understand electricity. So I did a dumb thing tonight. I took my EMS out of line. It kept dropping service for a 2 minute reset showing a PE4, Low Voltage, error code. If I remember correctly it drops service at around 108V. I know 108V is really bad for air conditioners, but at this time we are not running A/C. Here is some more behavior information. When the power comes back on, and before the EMS enables, L1 and L2 are showing 120v and 122v. All good. But when the EMS activates the RV the L1 drops to 110 and L2 to 109. AMP draw is between 15 and 23. Well below the 30amp limit. Hmmm, watts going on here?
Ok, I know that when you put 50amp units on 30amp posts over and over again the breaker gets worn and build up resistance. Ranger here assures me they have replaced the breaker recently. It is not warm to the touch at anytime. I am not thinking I have a weak breaker.
Line drop from usage, that could be a possibility, we are strung out at the end of the line and I have no idea what else is connected. And it does tend to drop at times when other folks would be doing morning/evening chores/cooking etc.
I am pretty careful about balancing our electrical usage on a 30amp post. Water heater and Refrigerator on propane settings. A/C set so that only one would come on, if it all. But we still get the PE4 low voltage disconnect.
So I did the unthinkable tonight. I pulled the Progressive EMS out of the line.
I know, I am asking for trouble. But I have had Progressive EMS get finicky and/or go south before. We will still mind our W's and V's and be real careful with the A/C units. Tomorrow I will dig out the old analog V meter and plug it in to watch and see what happens. At this point, I am kind of thinking the Progressive EMS is acting up. Definitely out of warranty.
