Quality Of Electric Outlets

I was not aware of the quality of the outlets that Airstreamairstream installedClick image for larger version

ID:	338705 in the Interstate. I removed this outlet completely as I am making room for additional cabinetry. I can’t be certain, but this may be responsible for some intermittent problems that some users may have with the outlets in their Interstate. I will be changing all of mine out to better quality plugs in the near future.

In my 5 Airstreams over the years, I have had multiple instances where I replaced one or more outlets with regular outlet boxes from HD or Lowe's. I use the repair boxes that mount much like the RV boxes I removed.

For instance, I replaced the single outlet just inside the door of my trailers with a quad outlet so that I could keep a voltmeter and a neon indicator permanently plugged in and still have an outlet available.

In every case, there has been plenty of wire length for any changes I made.

The RV boxes are designed for fast and cheap assembly and leave much to reliability.

Thank you for the input. I was contemplating solutions but had not yet arrived at a good fix. Those repair boxes sound like a good idea.

Yes; the outlets that airstream installs are clearly for reduced cost and speed of installation.

Looks like another cheaper labor saving device made to fail. I'd replace everyone with a good quality outlet and save a lot of future frustration.

Yup. Surprised? Nope.

Wake me when an American Manufacturer does something that actually increases reliability and longevity and manufacturing costs.

I tried to use a residential box and there was not enough depth between the inner and outer walls. Then I tried a "shallow wall" box - still a no-go. I ended up getting a replacement "RV" outlet which is an outlet and a box combined. They are difficult to install well in that they just pierce the insulation and I can imagine that the connections do not withstand vibration well.

You can use the Carlson oldwork 1 1/2 deep shallow boxes or the slide in pop in boxes.

Same situation with us in our EB .... and the cut outs in the inside alum skin are also horrible !!!

I must have been doing something wrong or in an odd part of my trailer. The one with the curved back (for rotating into the wall?) wouldn't go in. I tried the "shallow wall" box like you showed on the right. I couldn't get it in either. This was on the front wall of a 2001 Safari 25.

Wow, I can tell from this thread the same thing I've noticed elsewhere - that a few of us techie old-timers have reduced our use of, or stepped away from, this forum. (In my case, it's because I'm working on a public service project that has vastly curtailed my usual van-related activities for the time being.)

Those ^^ comments and those ^^ pics -- and not one retort about the suitability of the wiring shown therein.

Quoth one of our electrical engineers, "Solid core residential wire has no business on an RV."

In other words, the quality of the outlets (thread topic) is the barest tip of that particular iceberg (which one of the other techies would have pointed out sooner if they were actually here as often as they used to be). The argument has made that, because of the application, that wiring is not the safest to start with. It is subject to constant vibrations in a moving vehicle, which can lead to stress failures over time, which can lead to short circuiting and maybe even fires. Stranded wire, properly installed, would reduce those risks.

If you are interested in that line of discussion, you can pick up a previous sidebar via this permalink here.

My husband and I have replaced all of our rig's accessible wiring with stranded. IIRC, we have one OEM line that is buried beneath appliances and cabinetry that we have not been able to reach yet.

I’m not sure what your comment means about the “techies having stepped away” from this forum, but I have 41 years experience in the electric industry as a power plant operator, a controls designer and installer and energy consultant. It is my opinion based on my years of experience in the industry that these types of outlets are not the safest. The RV industry is not subject the NEC, which in my experience provides the greatest level of safety. These outlets that airstream has installed would not pass NEC inspection in any type of application, stationary or mobile. In these outlets that Airstream has installed, there is minimal contact between the wire and the outlet conductor, and the application torque is not controlled in anyway. Both of these reasons can lead to high resistance, intermittent contact, and failure. Quality outlets in motorhomes is especially important because the greater the current draw, the more important good contact between the conductor and the outlet. In many cases, motorhome owners are plugging in electric space heaters, probably the highest current draw device that you can install an outlet.
