Danger of chopping MC4 extension cables in half

[marionw]

I was preparing to create a PV extension cable today and sat there trying to figure out which connector to put on which wire (red/black). I got distracted and worked on other tasks and haven't made any progress on the extension cable.

My line of thinking is that it doesn't really matter which connector goes on which wire as long as the other end of the wire uses the opposite connector. So on the positive wire, a male connector goes on one end and female on the opposite end.

Prove me wrong.

I gave away two PV extension cables with my RV when I sold it a week ago. Now I'm wishing that I hadn't been so generous and had kept one of the extension cables.

Generally the Female goes on the "Hot" end of a cable (i.e. extension cords)

For me it was using the wrong pin when crimping, the male pin goes in the female connector, needless to say I’ve snipped off 3-4 MC4 connectors enough to learn my lesson.

I blame my 2 year old who was “helping me” but placing every screw he could find in my pockets. lol
