Oddly wired Distribution Panel

May I compliment you on a nicely portayed and laid-out question.

Thanks all for the input.

smkettner: nice catch, that 30amp breaker has to go, it has a 12g wire going to the AC.

wa8yxm: Thanks, I have no generator. My current WFCO55 was an external standalone, plugin converter. So the PD9260C is an easy upgrade.

DrewE: Correct, I misspoke, but that breaker has been breaking a lot when using certain circuits.

A 50AMP Trailer is provided two 50AMP ZONES with it own circuit breakers to use. The RED and BLACK wires come from each of the two available 50AMP zones from the pedestal.

Don't get confused by seeing a full size 120VAC circuit breaker being substituted by two half size 120VAC breakers. These are both valid circuit breakers - just different physical size width size. The WFCO 50AMP circuit breaker panel is provide with 8 full size holes for circuit breakers to be installed. IT is normal to have two half size circuit breakers installed side by side in a full size circuit breaker hole.

i.e in my 30AMP WFCO 120VAC circuit breaker panel I have five lfull size holes for circuit breaker. I use one full MAIN circuit breaker for the MAIN 30AMP rated circuit breaker. This leaves my four remain full size hole to mount additional lower rated circuit breaker which can be filled with four full size circuit breaker or eight half size breakers. In my case i am using the half size circuit breakers so I have control to a total of nine separate circuit breakers in the 30AMP panel.

This allows you to have more circuit breakers in your system. Each of the half size circuit breakers will perform independently...

I really don't see anything odd about your dual zone 50AMP circuit breaker layout. Like said above if you want to re-distribute which zone is being used for certain appliances just move the HOT wire to the 50AMP zone you want it to use.

Hope all of this makes sense haha...
This WFCO panel ID shows what I am saying...

This layout appears to be using three full size circuit breakers and eight half size circuit breakers with one empty full size circuit br3eaker hole for future use.

If the 15A breaker is working properly and the connections are tight and correct, the 14 gauge wire isn't getting dangerously hot. That's the whole point of having the breaker there—to ensure that the current through the wire is not excessive so that the wire overheats.

If you have a built-in generator, make sure it's wired to power both legs before moving circuits over indiscriminately.

That is far more common then you think.. IF your coach is indeed 50 amps, you can re-balance, putting at least one of those dual breakers on the left, I would/did in my coach.

Also, you may wish to make sure that is how it works (This takes an ohm meter and NOT being plugged in) They may have changed the bus arrangement in the box Mine is a 1 2 1 2 1 2 type not a 1 1 1 2 2 2 type But then mine is a progressive Dynamics box, not made in China.

Now, on the issue of Progressive Dynamics, You might want to look at the 4600 line, May (or may not) fit in the space provided by gutting the WFCO better.

Since I can not possibly upgrade the converter Damon gave me.. I do not know (Progressive Dynamics 9180 with optional charge wizard, basically the same as what you are considering, in fact other than size it is identical).

Once you drop in that PDI wizard job,, You too will be unable to upgrade.

Move one of the A/C breakers and it's companion CB to the left of the main breaker and you'll have better balance, maybe another heavy load like HW. The WFCO only uses a few amps so no reason for it to be on a separate CB but I'd put the new charger on it's own CB.

I would snap in three new breakers and start moving stuff over.

Also that 30/20 breaker.... might need to be replaced with a 20/20 or lower.

Looks like your RV received an optional 50 amp power upgrade but everything is wired using the breakers from a 30 amp set up.

Check ALL wire sizes. #14 should be 15 amp max, #12 should be 20 amp max. That 30 amp needs to have #10 wire.
