50 amp cords

When I connect my 50 amp cord to my 50 amp extension cord, I have a heck of a time getting them apart. Anyone know of a way to make that easier?

    Yes. Dielectric grease is an INSULATOR and is not intended to be put on conducting surfaces. It is intended to be packed AROUND a connection after it is already plugged together to keep out dirt and moisture. Even using it that way is NOT good for connections that are often unplugged.

    They make conductive grease that has a high graphite content.

    But just spraying a little silicone lube on the pins might help a little. They really do NEED to be tight.

    Fortunately this is a myth.

    Prove me wrong :)

    Go out to your rig yank the battery cables. Gob the grease on. Then put the cables back on, hit the starter. Again. Again. Twenty times. Then grab a brewski and wander around for the rest of the day scratching your head. A year later you'll remain wondering how and why.

    Theory always takes a slapping when it faces practical experience.

    Maybe some dilectric grease on the prongs, but you really want the connection tight. If it's loose you run the risk of arcing and resistance heat buildup and possible plug failure, i.e. melting.

    So time to hit the gym and build up those pecs. :)

  • I watched a guy pull his apart last fall with a pretty good method. The female end had a handle on the back. He had a nylon strap looped through the handle and he put his foot in the strap and pushed it down while pulling up on the plug. Looked much easier than pull apart with your hands.

    I sometimes need to use a flat blade screwdriver to seperate them. but PLUG DOGS. these are nylon wrappers that go around the plug. alas, that does not help on the outlet end.
