No 120 volts to the rv.

While in a campground near Dayton Ohio I lost my 120 volts to the rv.
This is the second time this has happened. I arrived, hooked up to the shore power with a "Surge Guard" surge protector between the 120 volts and the rig, which allows the power to come on after 180 seconds.
This worked fine for about 2 hours then all of a sudden the 120 volts quit and never came back.
I had 12 volts via the battery and 120 volts via the generator.
Now I am booked in to have this problem looked at at the local RV dealer but not till the end of July.
If anyone has any ideas or what I can test for it would be appreciated. I did check all the 120 volt breakers and nothing seemed to help. I'm wondering if there is a problem with the convertor box where the 120 volts attaches, or now after doing
some study perhaps its the transfer switch as you fellows mentioned.
Hopefully I have given out enough information. Thanks in advance.

  • The box with the 180 second delay may be a Surge Guard/Protector. Does it have warning/test lights on the box or a digital readout? Is this a box you connect to the park power and then plug in your cord?
  • OP is probably thinking of the transfer switch.
    Normally the transfer switch time delay is wired to the genset to give it a little time to level out.
    My guess is the transfer switch has failed.
    It is normally located near the converter.
  • Not sure what a "capacitor box" is that delays turning on the 120 vac, but that is the first place I would look. Can you bypass it?
