I have removed the panel on the reel. I have insured the connections were and are tight. Also, I checked voltage at pedestal and at cord connection to reel. No voltage drop here on both lines. The issue I am trying to investigate is what about the connection between the reel and the cord inside the rv that will go to the EMS. I do not see it as a breaker issue because my EMS is before the breaker box. And it is the EMS that is seeing low voltage. Also, breakers monitor amps not voltage.
