Planing is the key.
For loading the circuits just add up an estimated wattage. For 15 amp circuits I keep it under 1440w. No one may agree on genaric numbers but here are mine:
Keyless / pullchain 100w
Vanity light 250-300w
Bath fan 50-100w, light add 100w
Sconce 75w
Cieling fan w/light 300w
general rec 180w
5 OR 6" can light 75w
3 OR 4" CAN 50W
coach light 120w
Chandelier 300-600w
Flood lights 200w
closet light 40w
smaller cieling light 120w
4' lay ins 200w
Most numbers are on the higher side.
Kitchen appliances are all dedicated and at least 2 counter top circuits.
For us a middle of the road bedroom is 1 circuit. A larger master bedroom with extra lighting gets 2 circuits.
