The ones you buy are going to come with molded ends that are waterproof. Can you make one that is waterproof for laying out there in the pouring rain?

Molded on factory ends are certainly more "waterproof" than plastic aftermarket ends you may install yourself but it's not so much the connector that's the issue but the connection between two 30 amp (or 50 amp) cables that isn't in any way "waterproof" or even "water resistant". If you really expect these connections to be exposed to heavy rain the solution is to isolate those connections so they're completely protected from rain and pooling water. I did that by using Plano ammo boxes which have a rubber seal in the lid that ensures a watertight seal with the box ... works like a charm so I even use them with the factory molded on ends as well. :B


I really like your plastic box.
Do you have any problems with condensation in it?
