Connecting two 50 amp service cables together?

Is there a connector that can be used to join 2 service cables together just in case the pedestal is just out of reach? I have 2 cables but both have a male end and a marine screw on female end.

    IIRC, HUD limits 50 amp power cord connections to a maximum of 36 and a half feet in length.

    You would be very unlikely to have a HUD inspector check you hookup, but in the event of a fire, etc. damaging multiple units, a code violation noted by a fire inspector could end up with you found to be responsible.


    With RVs and campgrounds I can't envision that ever being possible and even if it were I seriously doubt this would fall under any kind of code enforcement to start with. I sure would not worry about this scenario.

    Now you might ruin one of your cords or the pedestal from burning up a connection, but that is a whole other issue.

  • I built my own 75 foot 50A cord (to reach the outlet at my Father In Laws, when were on the curb) and i use it in our storage bay so i don't have to roll up the cords every time we go out.

    If you want to build your own expect to pay 4 bucks a foot for RAW 50 amp cord, in a flexible (SO/SOO) jacket with 6 ga.3 conductor - 8 ga 1 conductor (commonly referred to as 6/3-8/1).

    You can buy the plug ends from camping world (and other places) - Power Grip Plug

    OR you can buy a 30 foot 50A Extension Cord from camping world (and others) for 100-150 bucks

    google is showing some results of 100 foot 50A (generator) extension cords for 300 bucks, but you'd have to adapt or change the ends.

  • If you have two 50 amp shore power cords, a 50 amp 4-prong generator adapter can be used to connect the two cords together. We have a 30 amp generator adapater that we use to join two 30 amp detachable shore power cords together when we need over 25'. We always carry a spare 30 amp power cord everywhere in case one gets damaged or stolen.

    That's a different twist lock configuration- I don't know the NEMA number off the top of my head, but the RV inlet has 3 blades plus the shell as a ground.
  • That's too bad. It works in the case of 30 amp services.
