Every bloke has a random set of plugs and connections in a drawer or box.

In the past few days I had to buy a random connection that I used to own.

Here is a collection of 7 Strand, 5 strand, and single strand solid copper wire. I've just rewired my trailer after dragging this a good portion across a continent.

I am going to throw this out, but only because I used it. (Not pictured is the length of cable I'm keeping)
