no power in any of the 110 outlets

[John From Detroit]

Sorry to tell you the WFCO converter is not the culprit.

120 volt systems are protected by Circuit breakers. NOW here is a suspect list.
But first.. Does the air conditioner work?

IF NOTHING 120 volt works, Fridge says GAS. A/C does not work No hot water on Electric.
THen start at the park.. Make sure there is power to the outlet you are plugged into  I have seen some circcuit breakers in parks trip real real easy...

Now I have a replacement plug on my power cord.. Guess why (not the original reason but it is the reason I repalced the Replacement)

If you have a detachable cord check for power at the outlet on teh cord. (Found one where they messed up at the factory .... Note I'm not a RV technician I don't do this for a living just help the guy next site)

Then you have, on a motor home (not often on a trailer) an Automatic Transfer Switch

FInally we get to the circuit breakers  A trippe main will shut you down.

IF the A/C and such work.. Then the above does not apply.

Some RV's have an INVERTER. now if you do you will have a big breaker (likelu 30 amp as a branch breaker.. Inverters either have Circuit breakers on them or feed a SUB PANEL (2nd breaker panel)

Finally for selected outlets you have the GFCI which I gather did not pass test (no power_) but is likeluy good.


FInally.. I had a bunch of loose screws in my Power distro panel. Once tightened many things worked better.

It really sounds like you need assistance from someone who has a basic understanding of electricity.  You also should really consider getting a voltmeter to help in your troubleshooting (and learn how to use it). Don't go overboard on the cost of a meter, there are many reasonably priced ones for home use out there.

As John (and everyone else who has replied) states, start at one end of the electric path (campground hub) and follow the power until you find the interruption.  Be safe, don't touch any bare metal inside any of the electrical boxes. (That HAS been known to cause health problems in California and everywhere else  ).  Be sure to look closely at the circuit breakers.  Sometimes they trip and only go part-way to the "off" position.  You could not notice at a glance but by touching the breaker switch you may feel it being "loose" or wobbly.  The best way to reset one is to turn it "off" and then back "on".  This re-engages the spring inside.

As far as the GFCI circuit, these are built to sense a difference in current flow between the neutral wire and power wire.  A short circuit of power will cause a flow of energy onto ground (or you) and not the neutral, and cause the imbalance of current to "trip" the GFCI.  If yours is "tripping" (and hasn't been smokin' the whacky weed lately  8) ) then there may be a loose connection or cross path leak somewhere that can cause the GFCI to Trip out.  This can even be the neutral wire finding a path back to the panel without going through the GFCI receptacle.

Good Luck and BE SAFE!
