120v wiring failure & good news on fridge outlet


Recommended Posts

Last night I heard the fridge gas ignitor kick in, which shouldn't happen because we're on shore power and the fridge was on Auto. This morning I went looking for the 120v fridge plug and didn't find it behind the kitchen drawers. It's actually under the drawers in our 2022, away from the water hose, so that's a design improvement.

The fridge was plugged in. (There was even a big ziptie to hold the plug in, but nobody at the factory bothered to actually connect that.) My multimeter said the outlet was dead.

Tracked the wire back to a junction box on the water heater and found this inside:

Best guess from looking at it is that the fridge wire (top in photo) pulled partially out of the splice connector and overheated. There's no strain relief entering the j-box. I was lucky enough to find another splice connector lying in the bottom of the hull (dropped at factory) so I cut off the burnt wires, restripped them, and used the "spare" connector to reconnect them. Then I tied the two Romex cables together with a zip tie just outside the j-box to add some strain relief for the connectors. Seems to be OK now.

😮 That’s the connectors they use in the factory?? That can’t be to any kind of code. Yikes!

Even wiring the simple AC electrical system I adde to my tiny squaredrop I used terminal blocks! Same with the DC side.

Thank you Steph & Dud!  I really appreciate posts like this one, because it gives me an opportunity to figure out a better solution before I experience a similar problem.   I’m disappointed that it is necessary, but it comes with owning any RV (or boat), even an Oliver.   John Davies mentioned the shortcomings of AC Romex and the residential junction boxes in a recent post.   This prompted me to make a note on my task list to inspect all AC wiring that is accessible, and improve the installations if feasible.   This post confirms that concern.   I did a quick check on RV best practices and came up with a good article and reference to marine codes.

120V Wiring for Campers

WHAT Type OF WIRE IS NEEDED FOR 120V OUTLETS In a Camper?

ALL wire in a camper must be stranded wire. This includes circuits for 120V outlets. Wires in a camper must be stranded wire because solid core wire (like the Romex used in the walls of your house) will, when subjected to the vibrations of rattling down the road, will work harden and break over time. For this reason, solid core wire like Romex is EXPLICITLY forbidden in marine applications (boats) by ABYC E-11.

Those are Wago lever nuts.  They are NEC approved as an alternative to wire nuts for 120V connections. 

They are easier to use than wire nuts, but are much more expensive.  They make it easier to see if you have a solid connection during assembly (because they have a clear plastic window through which you can see if the wire is fully inserted) , unlike wire nuts.   When properly installed, I believe they are also more reliable, and less likely to shake loose from vibration (such as when towing) than a wire nut connection, as they have a lever than locks the wire into the connector.

I am not an electrician, but have done all of the electrical work on the 4 existing homes we have owned for the past 40 years, along with the new home we moved into in 2020.   I have had to troubleshoot dozens of shorts caused by loose wire nut connections over those years.

Neither type of connector is foolproof, and as illustrated by this thread, all require attention to detail by the installer to avoid problems.  I suspect the wire that shorted was not fully inserted, and visually verified through the clear plastic window in the lever nut, during the build at the factory.  Sloppy wire nut connections also cause shorts, but they are harder to detect during installation because wire nuts don't have clear plastic windows.

I like Wago lever nuts so much I used them when wiring our entire new home.  No issues yet after 2+  years, but I checked all of my connections to ensure full insertion during installation.  I prefer Wago lever nuts over wire nuts.  I am pleased to see Oliver using them.

Thanks, @Rivernerd I'd never heard of those before. Learn something every day!

I avoid wire nuts whenever possible, too. And I can't think of any time I've used them with stranded wire, which is what should have been used in the trailer. That's why I used crimped terminals with heat shrink insulation in all of the above connections, and anchored them to fixed terminals.

I'll look into the Wago lever nuts for possible home use. Thank you.

Again, I have to wonder if the speed of production is the culprit. I know Oliver has been ramping up production numbers in the last three years, which puts more pressure on the line workers. With that pressure I think it would be easier for the person(s) installing the wiring to miss something, resulting in this post. A sharper focus on quality control will benefit OTT, and I hope they're discussing this on a daily basis.

I will be picking up my trailer in a few weeks and all of these issues I've been reading about are concerning. I'm happy there was not a fire associated with this poor workmanship.

Service told me they were forwarding this incident to the Engineering and Quality departments for review.

Olivers aren't perfect, nor are any other RVs. Just looking at other owner forums and watching YouTube will show you that. I'm still hopeful that the overall better design and materials used in Olivers will make this trailer our favorite eventually. I will say that the Service department has been responsive to our problems so far.

Wow.  Is OTT using Wago's extensively in the new trailers or was this just a one-off use?  If yes, this is an important question.

I have used WAGO's a bit on some connections that I'll likely be getting into.  For example service to the pump and installation of a second load transfer switch to the A/C.  But I am hesitant to do so for high vibration applications. Specifically such as the Houghton Relay Mod for their fan.  

QUESTIONS

For high vibration applications that are a PITA to get to, would you use WAGO or Wire Nuts?  (Both of which would need good strain relief of course),

What connections are used in aircraft?

I am a WAGO connector fan for circuits within their approved rating; properly sized crimp connectors and binding posts for bigger stuff.

Clamps or cable ties where possible to limit vibration. I also wrap 2 turns of trimmed-down black tape around the Wago "levers" after making and inspecting the connection to keep those little levers from getting caught on something and opening up when folded back into their junction box.

What  AWG is your break point between Wago's and Crimp to posts?

I find WAGO Lever Nuts are extremely useful when testing or troubleshooting circuits and combining different AWG sizes.  So to answer your question, I use the 221-4xx series up to 12 AWG and the 221-6xx series up to 10 AWG.  I also use tape on the levers just like I do on wire nuts.

I have only used the same sizes as mossemi above for 24-12 AWG and 10 AWG (stranded in RV and boat). I don't know if there are larger ones available or not. Generally the Wago splices are in junction boxes or fixture enclosures. Crimp connectors for #8 and larger are on binding posts / bus bars and usually have some sort of protective cover over them...
