Question about 50amp inlet plug

What is the deal with the plug on the side of my 5th wheel? There is no way to get the collar to tighten up or to keep it from going cross threaded !! The threads seem to be ok on both the recepticle and the 50 amp cord but after I push it in and twist lock it I can never get the collar to go on which would make it more water tight and help with the stain relief of the heavy cord. I have considered a right angle adapter which would possibly make it easier to start the threads, then plug the heavy cord into the adapter. Anyone done this? I'm sure some company makes a better quality plug. When I was in the Air Force we had heavy cables that connected two radar trailers together. They were made from metal and once tightened they were water tight and strong.
  • In seven years of using a right angle adapter in all kinds of weather (including tropical storms) I have Never tightened the locking rings and have never had the slightest water intrusion problem.

    I bought it for the strain relief and it does that just as designed. My feeling is that the locking rings are overkill for a fiver. Maybe for a radar trailer (We used them on our radio intercept huts in VN), but for an RV??
  • I too use a right angle adapter to relieve the tension BUT be aware that sometimes, as with mine, the receptacle might be 90 degree's off causing the Right angle adapter to hang oddly. I left it as is due to the right angle adapter being a "one piece" (vacuum molded)set up. I didn't really want to try and turn the receptacle on the MH to get it to hang straight.

    I use a right angle adapter to take the load off the receptacle, never take it off the 50a cord..


    Same here, it makes that angle just better.
    I got one when they were cheaper than they are now. ITS a Marinco 1RPC50RV Right Angle Locking Adapter. $87.00 at Amazon.com now.

  • Check out Smart Plug.....http://smartplug.com/

    I recently changed from a 30 to 50 amp service so needed to get the inlet for the trailer side of the connection. After looking at videos was convinced Smart Plug is a better mouse trap. I'm glad I went that way, so much easier to wire up, the install pretty straight forward and comparing to an twistlock 50 amp I had on an older rig, a much more solid feel.
