Today the power went off at our "home" rv park site. After about 2 minutes the power did not come back on, so we went out to check the portable Progressive EMS. It was still flashing the "testing" light, the reading said E-0 but then also PE-2, which is open ground. We disconnected the EMS and looked for any obvious issues. The box itself was warm. The power cord was slightly warm, and one prong of the male end of the cord looks darker than the others. The prongs of the EMS male plug look fine. The receptacle on the EMS looks fine, but has a slightly "hot plastic" smell. The plug into the coach is fine, as it is the new SmartPlug connector we added in February. (cool to the touch and prongs look perfect.)
We had this same scenario (EMS reading E-2) happen 2 weeks ago when we returned from our trip to Fredericksburg and plugged into our home site pedestal. At that time, I thought maybe the plug didn't make a good connection into the EMS box. We unplugged and replugged and all seemed good. The two legs are reading consistently within one volt, and between 117 and 122V depending on the time of day.
Our temps have been in the 100s the past few weeks, so I know all the rvs are demanding a lot of power in the park.
We have a portable SurgeGuard EMS that we carry as a backup, so we plugged that into the park pedestal... it doesn't show any readouts, just lights, and so far it checks out good.
So now I am concerned, could this be a bad shore power cord issue (male end is encased totally in the plastic) or the beginning of my EMS failing? The shore cord was new in February. The EMS is about 3 years old (fulltime use).
Tell us what to look for?
