Well I'll be, I just checked the drum and it says 6mm td marine
then it says 4.59mm square.
Okay well I'm mostly led and energy efficient fans so I'm way overkill on my wiring but I did it this way to maximize longevity and have plenty of room for resistance etc. it's a good thing I wasn't maxing out the wire based on 6mm. Sheesh.
I'm still hunting for more correct connects in Australia but no luck yet.
I agree with not wanting to screw down a screw against the fine strand. Btw that's the point I got to before when trying to find terminals. I bought a box of twin screw brass connectors I planned to use diode grease and seal with electrical epoxy
potting mix. But then had a change of heart as I'm not comfortable screwing the screws to the fine strand.
On another note I have read all mainsails blog and agree with his methodology however he does not cover this type of connection, well at least that I've found.
I do know many have had success using copper tubing for making custom battery
lugs and that's where I was getting the idea.
Again I only have 20mm free clearance above my headliner
. I really need to use something that is low profile.
I can see why they originally twisted the wires and soldiered. In all fairness the connections were still good after 26 years and the failed ones were at terminal boxes. If corse the terminal boxes happened to be more exposed to moisture.
