need help - several electrical issues / concerns

Brand new 2015 cardinal 5th wheel model 3825. living room in front, bedroom in rear. this may be lengthy but I want to explain fully as I have some concerns about the electrical system.

Here is the set up of the trailer. we are at home. 25 ft 110 electrical from garage to trailer. connected to a 110 to 30 amp adapter. connected to a 30 amp to 50 amp adapter. connected to the 25 ft 50 amp cable that came with the trailer. the intent of this was to be able to run the residential refrigerator in the trailer.

I was able to get the refrigerator running by turning on the inverter. but with the inverter off do 110 to the refrigerator. I know that the 50 amp circuit is wired as two 110 circuits with different busses on the distribution panel. the distribution panel is a 50 amp progressive dynamics panel and it appears to be divided into to separate sections. the top section has the following 6 breakers labelled: SO, AC, WH, WASH, REFER, DRY. to the best of my ability I verified that these breakers DO NOT have 110 power going through them. (no power to refrigerator, put 110 test plug into receptacles for washer and dryer). the bottom 6 breaker seem to have power and they are labelled REC, MICRO, GFI, 2AC, CONV, FP. I was able to confirm 110 power at the microwave, gfi outlet, the converter. so it looks like these are getting 110 power.

the immediate concern is no 110 to the refrigerator. so I thought turn the inverter on and the 110 to the converter will charge the battery and supply power to the inverter to run the refrigerator. tried this and the inverter kept powering off (probably the low voltage safeguard.) I went to the lieppert leveler and it has an option to show battery voltage. it read 11.6 volts. i have a progressive industries surge protector and it was saying 0 amps on 1 circuit and about 3 amps on the other circuit. but we had some fans running so shout them down and the second circuit showed 1 amp. so my next concern is shouldn't i be using way more than 1 amp as i would expect the converter to be trying to recharge the batteries? by the end of the day the batteries were down to 11.5 volts. a final concern about the 110 wiring. the 50 amp cable plugs into the rear of the trailer (the trailer is 40 feet long). it then appears to run up to the front to the generator compartment where it goes through the surge protector. and transfer switch. note that the batteries are up front in the generator compartment. after that the incoming 110 must travel about 3/4 of the length of the coach back to the rear door when the converter and distribution panels are located. then the converted 12 volts have to travel all the way back up to the generator compartment in front to connect to the batteries. this seems like a lot of length!

I would appreciate any observations that you may have. one option i am thinking about is to move the 110 circuit for the refrigerator off the upper or unpowered bus down to the powered bus. probably swap it with the fireplace. but i still have the concern about being able to charge the batteries. i believe it is the 30 amp to 50 amp adapter that puts the power onto only one of the 50 amp legs. does this mean that if we plugged into a 30 amp circuit i would only get power on one leg and would again not be able to run the refrigerator?

Thanks in advance

Guess the first thing I'd try is running a regular extension cord, and after removing the outside fridge access, plug the fridge directly into the cord. You can also just leave trailer plugged in as you had, and text that fridge outlet with a volt meter. Try it with 110 hooked up, and again with the inverter on. ?? Might give some insight into what's happening. Could test the end of your extension cord as well.

to all, please excuse me for being an idiot. I finally figured this out. we took the trailer out of storage and brought it home to get it ready for a trip. I never changed the battery disconnect switch. this is why it was not charging the batteries and running the refrigerator via the batteries and inverter. once I changed the switch I have the refrigerator running. sorry for the alarm.

That still doesn't answer why you only have power on half of the distribution panel??

I know, I've been thinking of that. I thought the 30 amp to 50 amp adapter was supposed to put power on both legs of the 50 circuit. we're taking the trailer out for a few days today and I am going to verify everything. it will be a real simple test to see of the hot lead on the 30 amp adapter gets outputted on both legs of the 50 amp side. if it is not I will get a new adapter. if it is, the test meter and I will be exploring in more detail.

also going to relabel the circuit breakers. things like AC and AC2 should be AC front and AC rear. what is REC? going to find that circuit. I just like it spelled out! not for me as much as when somebody else needs to know. and you never know when that will be and how urgent it will be at the time.

I've often wondered the same thing. If you hook up a 50A MH to a 30A service, are you getting 15A on each leg or are you getting 30A on a single leg and nothing on the secondary leg. Anyone know the answer?

The adapter does not 'split' the amps to the two circuits the way to look at it is 30 amps total available. If using circuits on both sides of the 50 amp system you have to add up amps being pulled by each appliance and stay under 30 amps total.

My explanation on that was rather dumb.....thanks for clarifying. What I was trying to ask was if both legs on the 50A would be hot or if only one of them would be hot. I'm not real swift on electrical - obviously.

We have a 50 amp trailer, at home I have a 30 amp service. When I plug in with a 30 - 50 splitter it powers both busses of the distribution panel!

Using the proper adapter, you will share the 30 amps across both legs of the 50 amp.

Here is another thread that also has schematic of the way 30 and 50 amp RV's are wired, along with how the adapter uses a L1 "jumper" across both legs (L1 and L2) of the 50 amp.

drove to the campsite and plugged into 50 amp service. same thing, one leg is dead. so my multimeter, screwdriver and I spent some time dissecting the trailer. started and distribution panel and works back towards the power pedestal. finally found out that the is no power on one leg coming out of the surge protector (brand new progressive industries 50 amp hardwired). yet the display unit shows an input voltage of 117 on both legs. I had this unit installed by camping world a month ago and this is the first time we have used the trailer since. so I called camping world and have to take the trailer back and they will look at it. (in a week)!

OK - I have th exact same surge protector, except I installed it myself. Here's what you want to do:

1. Unplug from the power pole and turn off your generator (assuming you have autostart, you may want to flip the switch on the generator so it doesn't come on automatically).

2. Remove the cover of the surge protector. Inside, you'll see the card with the display on it. This just slips off the connector and it will allow you to see the actual relay in the rear of the device. One side is wiring coming from the shore power and the other side goes to the coach.

3. Check the connections at this relay. The two outer connections on each side are the hot lines. You'll probably find that CW (as usual) failed to tighten one of the four connections (two on each side of the relay) and you've lost power there.

4. If you don't find a loose wire, check voltage on each side of the relay. The center wire is the common.

5. If you find you have power on both sides, call Progressive Industries. Their techs are great. Tell them you have an emergency and are stuck at the campground. They'll step you through a couple of tests and, if the device is bad, they'll send you a new one. They have a lifetime warranty. They will also most likely be able to tell you how to jump around the relay to get things going again.

6. If all else fails, you can remove the wiring from the shore power side of the device, disconnect the device cord from your ATS and hook the shore power directly to the ATS. That's how it came from the factory. Sounds like more work than it really is. Just be SURE all power is OFF first!

Hope this helps. Good luck.

to all, thank you! finally got it today. I contorted myself to get to where I could open the cover of the surge protector. verified incoming voltage on both legs was 117 yet only got 117 on one output leg. so called progressive and spoke to a guy named dan. he told me to remove another cover and tell him what I saw. there was a piece of plastic in the cavity where the output neutral contactor was. he said this was not right and to remove it. I did and we tried the unit and it worked. that piece of plastic was from the small cover he told me to remove and in looking at the cover it was obvious that another piece had broken off that would have been over the output leg that had no power. I found a second piece of plastic on the bottom of the unit. my guess the camping world tech just forced this cover on and the plastic pieces broke off and fell into the contactor cavities and interfered with them. opening up the cover probably allowed the piece to fall out of the contactor so that now it works. bottom line, we now have both legs of power and can run both a/c's. it's about 100 here today!

Don't feel bad and there are no dumb questions. I have delt with both house and automotive electrical systems most of my adult years (and that's a long time) but 3 years ago when I got into RV'ing I was right here on this forum learning the differences same as you, RV electrical can be confusing until the little lite comes on and then we are all prone to go 'Now why didn't I see that right off'. Have a great day and camp, camp, camp enjoy.

Assuming you have a gas fridge, it sounds like everything not working is 110v. Have you checked that breaker? You said you're dry camping. Are you on shore power or generator?
