Re: Crimping Different Guages question

Agreed...stranded wire should not be spliced in the above manner. I'll stick with the crimp connectors.

Re: Crimping Different Guages question

I just strip the smaller wire back more and twist it over itself to increase the size. Then I use the crimp for the heavier gauge.
It may not be the "correct" way but has always worked for me

I don't know why no one seems to want to use a terminal that is specifically designed for the job?

That's obviously the best. Is that Anchor brand? I havn't seen those exact ones before.

The problems I've encountered have been that 1) They're one more more thing to buy and 2) a lot of things don't even have 20awg wire, for example my compass comes with like 26 or 28, my spreader lights were 20 or 22, and the GPS was also 20+. So the cases where it's actually blue to red are somewhat rare.

Is there a good solution for blue to smaller than 20? I've gone with either twist and shrink wrap (not super robust but easy), or fold over and stick in a crimp designed for something bigger.

Re: Crimping Different Guages question

Maine, you can't find those sexy proper connectors at the local hardware store!

But offhand...if a connector is big enough to fit 14/16 wire, and you slip one 16 and one 18 both into the same end of it...that's going to fit pretty nicely. So you strip a little more wire, feed them all the way through, crimp on both ends so you've got a double crimp in there as well. No big deal. Mail ordering the right extra ten bucks for postage, an extra week to arrive...not an unforgiveable sin to kludge it for a one-shot job, when you're not equipping a shop for repeat work.

Re: Crimping Different Guages question

I just fold the smaller wire back on itself, doubling it for the length of the crimp. With new LED fixtures and a boat whose wiring loom was sized for incandescent, this isn't uncommon. While I'm normally somewhat of an OCD perfectionist, I've never had any problem sizing the wire to fit the terminal in this manner. It also works when you have to use a ring terminal and the only ones large enough to fit the stud are oversize for the wire.

Re: Crimping Different Guages question

Or, you could do what the previous owner of my boat did... repeatedly....

Hold the wires next to each other, maybe twist'em once for good luck, then cover them with electrical tape, then sell the boat to me... sigh....
