Inside the mini junction box on the Dayton motor for my whole house
fan there are two types of connectors. One is a nut on a post. The
other is a spade lug. There is a knockout for a cable clamp.

How do I connect to these? Do I crimp the appropriate connectors onto
the wires in NM cable? For crimping connectors onto wire, it seems
like flexible wire would be better - not the solid wire in NM.

Either solid or stranded wire should work OK with crimped connectors.

What I'd do is solder the connectors onto the wires so I know they're
not going to loosen sometime in the future. Call me paranoid, but I just
don't trust connections that rely only on the holding power of a little
bit of sheet metal to work.

Soldering after crimping should take all of 5 minutes.

I'm surprised you would advocate that, David, since you seem to know a
bit about electronics.

Soldering a crimp connector is the quickest, easiest way to make it less
reliable. It makes the connection brittle, therefore much more prone to
vibration induced failure.
