Remodel circuit usage
I'm in the midst of remodelling a section of my house. I'm trying to decide which circuits to use where (they're all recycled from the previous interior which included a kitchen, full bath, and laundry).
Here's what I've got now: 3 x 20A circuits unused plus 1 x 20A circuit that also powers lights in the main kitchen's eating area (maybe 800W used) plus 1 x 20A circuit that also powers outlets in the main kitchen's eating area. 1 x 240V x50A circuit unused. Also, if needed, there's 1 x 20A circuit that I have already commandeered for garage lighting (now using 1280W).
What's the best use of these circuits? The new rooms include the laundry room, mud room, powder room, and walk-in pantry - need lighting, outlets, and exhaust (in the laundry and powder) to all be suppied. Also I need to power 600W of outdoor patio lighting, 200W of attic lighting, and 600W of adjacent family room lighting which are all currently dead. I need to power the washing machine and gas dryer (they can share a 20A, right?). Is it smart to have all/most of the lights on one circuit and outlets on another as was previously done?
Advice? (I'm going to terminate the 50A circuit in the attic for future use.)
