Right, that's done. One NATO to 50A Anderson adapter.
Turns out I'm a bit of an engineering masochist. This was the hard way to hang an Anderson plug on the back of my vehicle. I knew that before I went down this path and acknowledged it earlier in this thread. If you're similarly determined to make use of the NATO socket you paid for then go ahead.
I think there is a fairly small interest group for this. Pics tell most of the story, plus:
- Elke NATO plug with 50mm2 contacts for 2AWG cable
- I made two spacers from a piece of copper rod. 10.5mm OD. 7mm ID. 14mm long.
- I filled the cavity in the backing grommet with 13mm plastic barbed end plugs from my garden shed (example), after first drilling a 7mm hole in the end and taking off the peg tab. The barbs completely seal the grommet. This worked better than I expected. I added some heat shrink to tighten up the fit and protect the insulation.
- The spacers were tinned then soldered into the NATO male contacts to step down from 2AWG to 6AWG.
- The 6AWG cable was dip-soldered into the contacts at each end. I prefer to crimp but the NATO contacts are LARGE!
- The finished length will place the Anderson horizontal in the run to my camper. I have also put a new Anderson on my camper so it's fresh.
