Glad that you are both happy with them. One of you, I beleive got one with some masking tape residue still on the surface. If should wipe right off with some mild solvent.
I had about 4 different pieces of PVC scrap. 1 fit in perfectly, one would go in with some effort, and 2 were too large. I ended up sanding them by hand for 5-6 minutes and they slid right in.
Go around with a drum sander bit in your cordless, 'round and 'round 'til it fits.... :yes:
Working from memory, I'm gonna say yes...in phase. I'll dig around a little and if I misremembered I'll post a retraction.

They are wired in phase.
