Attaching 50amp cables with marine connections

[jeffreyhnewby]

I have two 50amp cables where one end is a female marine twist connection and the other end is a standard 50amp male plug. For the life of me I can't find a pigtail or conversion device that would allow me to connect them to each other. I believe that would require a female standard plug on one end and a male twist lock on the other. Any suggestions?

I guess I should have added that one of my 50amp cables is 30' and the other 15'. I use the 15' one whenever I'm close enough to the post since it weighs much less than the 30' one. However, I have to use the longer one about 25% of the time so I don't want to destroy either one. What I'm trying to figure out is how I can connect these two rather than buy a third cable to use as an extension.

Does your RV have 'twist lock' for power cord?

And you want to connect the TWO 50A cords together .......one plugged into your RV via twist lock and then the other cord connected to that one as an extension cord?

IF so....cut the twist lock off one of the cords and replace it with a standard 50A female plug....then you can plug the 'extension cord' into the male plug on the power cord that is connected to your RV via twist lock

Or just cut the twist locks off both and replace with standard 50A female plugs

You could remove the twist lock from one and install a 50 amp range receptacle.

Say again? So you need twist lock male to dryer outlet female?

Might have to build it. Home Depot should have these fittings in the electric isle.
