Shore Power Woes!

Do you loose power than have it come back on by itself?

Yes the power goes out and comes back on itself! Thanks!

As mentioned above, check that all AC power connections are tight from shore cord plug to main AC distribution center. Also could be faulty Main Breaker, flip it on and off a couple of times.

Why not turn absolutely EVERYTHING off.

But leave the microwave plugged-in and set the clock as a tattle-tale.

If it goes off in a day or so, then the power comes back on then turn the roof air on.

If the roof air runs OK for while then the power is being TOLD by something to turn off. Much different than a bad connection.

The trick is to find whatever screwball malfunctioning device is attempting to force you to take Prozac. A "smart" (he he he) voltage protection device may be at fault.

I had the same problem. Turned out to be a loose wire in the female end of the power cord (Marinco) that plugs into the motor home. There had been enough arcing that I had to buy a new plug and trim the end of the cord a bit to make a good connection.

If turning off and on. Sounds like a surge guard is protecting the system. From low voltage over load.
This is part of what it is suppose to do.
What is the voltage at the shore line conn.?

The voltage is 115-120V. As I turned things on the voltage dropped below 110. When the HW heater is turned on to electric it may turn off the power without a breaker tripping. The AC does the same thing. The difference is that the power goes out when the AC is running for a long time and the temp. outside the motorhome is excessive with high humidity. Even when the power goes out I have checked the main power panel and no breakers have not tripped. Breaker on power pole still on. The power cord runs into a electrical box inside a storage container and the connections to the RV are all tied together with wire nuts and nothing else! Thanks for all the suggestions.

Thanks for all your replies! The problem was a shorted auto transfer switch! Has been repaired under extended warranty.

I am fond of saying many RVers have a few screws loose.. Some of the screws I have tightened included.

The screws connecting the wires to the INLET on the side of my coach.

Several screws in the circuit breaker box (power distribution center)

ALL SIX of the six screws in a neighboring RVer's Marinco OUTlET (The end of the cord that plugs onto the "inlet" in the Trailer) YES all six, the dang outlet came off the cord in my hand.

I have not personally tightened screws in the transfer switch, but have read posts from folks who wished they had.

In short, ANY and EVERY screw in the electrical system.

Some RVs (Epically if purchased used) may have an Power line Monitor/surge guard system installed... Now where I am today,,, They mostly do nothing. But where I'll be this time tomorrow, When air conditioners kick in the shore power may drop below 100 volts AC (30 amp service) and when that happens.

Well they usually shut you off around 105 to 110.
