I keep popping the living room 20amp breaker
 
several times in the last few days i've noticed i have popped the living room breaker i reset and all is well i wonder if my power cord from home was too long and causing a voltage drop i had a 100 foot cord conected to my coach cord
just on a 15 amp plug i just shorten it to 50 ft and put knew ends on each end of the cord cause looked to be some melting going on with one end of the shore cord, its on a 20 amp circuit at home but i never pop that just the 20 in the coach
thinking maybe i have a bad breaker in the coach ??

First is it a breaker in the RV breaker panel or a GFCI outlet in the living room of the RV ?

What stops working when the breaker pops ?
A weak breaker still needs something on, that draws near the amp rating of the breaker, to pop.

If nothing is on that circuit and the breaker in the panel is tripping, you have a short somewhere.

Is the living room in a slide ?

The wires, that move with the slide, could get caught and torn up on something.

Be very careful with 110v extension cords and overloading them. As you noticed already, fires can start. I use a heavy duty construction extension cord for my 20 amp 110V storage. Expensive, yes, but so was my coach.

Are you tripping breakers when on 50 amp clean power?

Soppy 07-15-2018 05:22 PM

Would that breaker be for the air conditioner ? Most A/C units are on a 20 amp breaker. The 50 ft cord is too long to run anything but that draws a lot of power. As A quick check , fire up the generator and see if it still trips and find out what's running.

as a last idea i sat down tp read the owners user manual

as a last idea i sat down tp read the owners user manual
an din reading it is says when hooked up to 15,20 or 30 amp turn off inverter #2
above the toll window
i guess the toll window is the sliding window by the drivers side i hate so much
my drive way is so narrow when i store my coach i need to have my head out the window and its impossible to do it with the Toll window i guess its to hand someone a quarter for a toll,

so i turned off the #2 inverter in the breaker panel above the drivers seat
assuming that is what they are talking about i noticed my voltage went up in the coach from 116 to 119 now my next question if i forget (im Old) to turn inverter #2 back on what is going to happen if im operating on inverter only does to just take over a load and balance between them or is #1 inverter for some circuits and #2 for others ??

see photo of the #2 breaker i turned off figuring this is the one they discribe.

More things to read in the owners manual...... :thumb:.......:D

now im wondering if i turned off the correct one

i found out there is 2 places for #2 inverter
did i turn off the correct #2 inverter

you know when Quartzsite rolls around in 2019 and you all will be say there is that dummy he should have read the book

i turned off the first above photo #2 inverter i posted now wondering if i should have turned off the one in the second photo or both

Ron, it sounds like the breaker you’re describing is the one shown in the attached photo. In our 2018 45B Cornerstone, it’s located in one of two circuit breaker panels on the side wall above the driver’s seat “toll” window.

That breaker in our coach does the same thing you described in your thread title; i.e., it will trip every so often for no apparent reason. When it does, I reset it and all is well until the next time it decides to trip. Monitoring it over time, I’ve noticed it seems most likely to trip when shore power or generator power is turned on or turned off. And yes, it trips when on clean 50 amp shore power and when running the generator.

Until I saw your post, I just assumed I had a weak breaker and have been meaning to buy a replacement when I get around to it. If you’re having the same issue with the same breaker, I’m now inclined to think the breaker may not be quite adequate for the loads being applied to it. In other words, it may need to be a 25 amp breaker instead of a 20 amp breaker.

Advice from those of you with more 110 volt AC electrical system expertise than I have will be appreciated!

well, you most certainly do not want to upsize a circuit breaker.
Checking to find out exactly what that breaker runs sounds like a good thing to do.
About the only thing in the "living room" not on the inverter is the fireplace, and I bet it's not on in July.

I wonder if there is an AC distribution map on Entegra's site?

Jim, I'm well aware of that caution, but I also believe it's possible for an RV manufacturer to make an error when calculating which circuit breaker is needed for a given set of loads.

Any idea why this particular 20 amp breaker would work under normal circumstances but trip when shore or generator power is applied or removed? And why it only trips sometimes but not every time shore or generator power is applied or removed?

Hi Larry,

I'm reluctant to claim "expertise", but, I do have some experience that may be helpful.

That very same circuit breaker on my '18 Anthem tripped several times after we took delivery. I couldn't associate it with any specific event; it just tripped for no apparent reason. We lived in the coach for a month after delivery and, thinking that it could be a faulty circuit breaker, I purchased a replacement. The replacement exhibited the same tendency.

We stopped by the dealer on our way home from our month in it and asked their tech to look into it. To our great joy, he found the problem. And, in a couple of months post repair, it hasn't tripped.

He found a connection in one of the outlets (between the "Ent Center" shade and the "Dinette" shade). He was able to use one of the plugin circuit testers like this: Attachment 211124
to locate the problem outlet. He just inserted the tester into the outlet and wiggled it a little which caused the circuit breaker to trip.

His explanation, which made sense to me, was that the GFCI circuit breakers are very sensitive to any fluctuation in current draw on the circuit. A less than perfect connection anywhere on the circuit can cause the circuit breaker to trip. Even thermal expansion and contraction might be enough to cause some variance in current which could cause a GFCI circuit to trip.

I don't have the requisite "expertise" to suggest that your tripping circuit breaker is being caused by a problem outlet connection...but...mine was.

Pretty easy to plug in a 3 wire receptacle tester into the various outlets on the circuit and wiggle it a little to see if you GFCI circuit breaker trips.

Good luck.

Take care,
Stu

Thanks Stu - good info and definitely worth a try.

I already have a couple of those test devices, so I'll do some experimentation and see what I can learn.

Was the solution to your problem a replacement of the problematic outlet?

twinboat 07-16-2018 05:23 AM

So thru pictures, we discover that it is a 20 amp COMBO GFCI breaker, marked " living room ".

The tripping probably has nothing to do with amp draw or load on the circuit.

The picture shows more then one GFCI breaker and if they don't trip, its not something in the incoming power wiring.

I would first see if an outside outlet is on that circuit that may be getting water in it. That can cause ground faults.

If nothing found there, then it gets down to looking at each receptacle, in that circuit, for a neutral wire very close to touching a ground conductor.

If the neutral and ground touch, the neutral current will travel down the ground conducter and cause the imbalance that GFCIs monitor for.
