Electrical issue . No power to a breaker

[Bsbllage09]

Hi all. I’m new to the rv world and having some major issues with my electrical. So I have outlets that don’t work in my living room area and the ac don’t work e7 code. I checked the breakers with a multi meter by turning everyone off except main and turning them on one at a time and found the breaker mark general is the one not working. Shows a voltage of 5v. Now when the general breaker is off I get power to all other breakers. Now when the general breaker is on I lose power at breaker to the ac breaker and dryer. I’m at a loss with what to do. I hope someone may have some ideas. Thank you so much.

Welcome to the forum. Some more info would help. Start with year and full model of the trailer. Is the trailer a 50 or 30 amp unit and what is it plugged into? Plugged into a 50 amp pedestal, a 30 amp, or a 15 amp receptical at home?

Hi I’m sorry. It’s a 2013 keystone alpine 3500re 50 amp. It’s plugged into a Temporary 50amp pole ( building a house and living in it on property while building) I’ve tested the cord that plugs into camper and get voltage it was working great till yesterday

Have you checked all the connections on the breakers and the neutral and ground buss bars? Obviously remove power first. The main neutral connection (white wire) looks odd but I can't tell if it just the picture or not.

Was there anything that was changed or different before the issue? Also, is everything on the circuit turned off and or unplugged? If not, unplug what can be unplugged and turn everything else off on that circuit then energize the breaker and see what happens.

I still have things plugged in to the outlets that don’t work. Not currently there since it’s so hot with out ac but I’ll be back there in morning and I’ll unplug what I can and retry. What looks odd about white wire.anything I should look for? I’ll also tighten all up on the bars also. Could the converter cause what I’m experiencing? I appreciate your help

OK, you are connected to power. It is a temp pedestal. First thing I would do is check voltage on the positive legs and you should see nominally 120VAC on each between positive leg and neutral. Then I would buy an Electrical Management System. I use a Progressive EMS but mine is 30A for my camper. You will want a 50A. The one I use plugs into the pedestal (shore power) and my camper's electrical cord plugs into it. Here is a similar one for 50A campers:

I can't read the labels well on your pictures but your A/C will be 20A circuit breaker. A black wire will plug connect into it held by a stud type keeper on the back and a white wire will connect to the Neutral bus. This arrangement is the same for each circuit. Turn you power off (UNPLUG FROM PEDESTAL OUTLET). If some 120VAC circuits are not working but some are, likely a loose connection on the bus bar of on the back of the associated relay.

The two big fat wires in your picture go to your converter on the back of you power center (not real sure as yours is different) and the converter turns 120V AC into 12V DC and keeps the battery charged. Since your issues are 120V AC related and you didn't mention lights (12V) not working, I am guessing this is a simple issue on the AC side.

Again, get an EMS. An EMS is NOT just a surge protector but will protect you expensive rv electrical components from any number of issues which could fry them by shutting down power to the camper until the electrical (from the pedestal) issue is corrected. Who installed the temporary electrical supply?

[Bsbllage09]

Thank you yes I’ll look into that. Anything 12v works. My outdoor outlets work all my gfi outlet works. What don’t work are my air conditioning, tv, microwave outlet and 3 outlets in living room. Lights , water heater , etc works

[Bsbllage09]

Only thing that was different but was 2 days before the outage was I had my ac gasket replaced, so ac was removed then put back In.

Look at the left side of your picture you posted of the cover on the power panel. Both ACs, microwave, dryer and general - all the things that don't work. Sounds like you lost one leg of your 50A. You need to check that temporary power pole and plug. Read both hot legs to either ground or neutral, see if one of them is dead. If not you need to pursue that back to the power panel in the RV but it appears that is what you have.

[flybouy]

Agree with Danny. Have you cycled the main breaker in the trailer off then back on? Done the same with 50 amp breaker on the temp pole power?

[Bsbllage09]

I will test out all the suggestions tomorrow and post update. Thank you all so far for the help.

[Bsbllage09]

If by cycle means turning breakers off then on yes I’ve done that to all the inside breakers plus the breakers on the temp pole

[CedarCreekWoody]

The things not working appear to be on the left side of your panel. As described earlier it appears you have lost one leg of your power feed. Check your power pole first and work downstream.

I had a similar issue in mine and found out the breaker had just gone bad. Test the actual output from the breaker before it goes anywhere. Mine was tripping at 10amps or something. Also check you GFCI’s because a bad one of those can have backfeed and have the same issue.

[Bsbllage09]

Yea since people leaning towards a leg missing power I’ll pull the main breaker and test those lines first. All my gfi outlets work so retry sure not that Weird thing is none of my breakers tripped.

[sourdough]

A breaker wouldn't trip if the power was lost on one leg due to a loose connection etc. A VOM will tell you right quick if you have power on both legs. Check at the temporary RV receptacle to see which way the problem is. If one leg is dead at the receptacle go back to wherever the temporary feed for the ped comes from.

I would retest at the end of the shore power cord. There would be 2 live, a neutral and one group. The two live are the 'right and left' side holes in the plug.

A non-contact tester should beep for those 2 and not on the other two. Then go into the power center.

UPDATE!

First want to thank everyone for there help and advice. So I was able to figure things out. As several have said I was missing a leg. I pulled the cover off the temporary pole and the 50amp breaker was fine. So I opened the plug outlet and sure enough a wire was off and ground not hooked up to anything. Now maybe the wire got loose when pulling the camper plug out ok but ground was just loose not bolted to anything. Not sure how it ever worked. I appreciate everyone here. You guys are great !!!

I suggest you reassemble with the source to those wires OFF/Disconnected. I also still recommend an EMS as in my original post. This would have shut things down rather than the possibility of frying your electronics in your camper. I don't really understand the little additional ground wire unless it goes to a copper rod well into the earth. The green wire will ground your outlet and should be connected to a ground source from where you are pulling the power.
