Upgrading 220V wiring - need professional advice!

The Polaris in the bottom pic is rated 14-4 AWG.

I would need to buy two of these, right? One for the two hot conductors and one for the fused neutral/ground? Would a 3-port work just as well?

That's good hearing! These are semi-custom KraftMaid cabinets, all plywood construction. Unbelievably, the printed installation instructions that came with the cabinets (and posted on the Kraft Maid website) say to drill 7/32" pilot holes into the studs to mount the wall cabinets using the supplied #9 cabinet screws, which are very similar to GRKs but have a larger head. Looking at the size of the drill bit, I was immediately skeptical, and I'm glad I drilled a test hole because the holes are way too big, and there is ZERO bite from the threads! The screw just falls into the hole.

I think it would be important to center the holes into the studs. That has to be hard to get stuff aligned.

I am also wondering about using some metal French cleats. I guess that might move the back of the cabinet away from the wall, but it would sure seem to solve alignment problems.

Yes indeed! The screw holes from the previously installed cabinets are still in the wall. I am using those as a partial reference.

No they don't work like that. All the ports are connected. The one in the pic has two ports connected together, the part on top with the rubber plugs is where the set screws are located. So you need 3 of the 2 port.
