You only use XHHW-2 insulation???

I never go less than XJJY-4 insulation...

I was registering a little dubiousness about the THHN/THWN wires.

When we were wiring up the Castle, through the support arms, the Thrust Ring, the secondary support arms, and into the other Habitats, we exclusively used Silver-clad copper wires for anything smaller than busbars.

We had to make it ourselves, but what else were we going to with the extra silver anyway? Make bullets?
