Thanks for all the good info.
Would I be ok running my machine and router on one circuit, and the dust collection and any other accessories on another? The main reason I’d prefer to do it this way is that it makes adding an E-stop that controls both the machine and router a lot easier to figure out for my basic wiring skills.
@CrookedWoodTex, I wasn’t even aware of a UPC, so thanks for the tip. 
I’ll have to do more research.
