Power sources for disposer and dishwasher??

Yeah, I’m thinking of adding a garbage disposal and a dishwasher to this pole barn. Silly question… What powers these 2 things? I know the disposal uses a standard switch, but does it have a plug in somewhere?? I know the dishwasher needs a water in and a water discharge, but what powers it? Are they 110, 220, or something else? Don’t worry, I’m not actually doing the work; a contractor will be. I’m just seeing what needs to be set up.
I think dishwasher models vary so you’ll want to check out the model washer you are getting to be sure. Disposers are usually 110 but some of the bigger commercial models may use 220.

Lighting Design Help

I want to put recessed lighting in my living room which currently has no wall or ceiling lighting for general ambient lighting. The room measure 26′ x 14′ with standard 8′ high ceilings. The house is a ranch so installation and wiring shouldn’t be an issue. I am looking for help with respect to choosing an appropriate layout as well as proper sizing and wattage for the lights. Can anyone here point me in the right direction? So far I have been using the Home Depot 1-2-3 book and it mentions 6′ spacing, but little else. I can get some pictures of the room if that would be at all helpful. Thanks for any help.
