My husband and I want to work on our attic (about 400 sq feet) which has never been finished before. we want to make a master bedroom with a bathroom and a closet. There is a circuit on attic now, 3 way switches on the stire way to control one light, 2 other lights which are not connected with any switch. 2 or 3 receptacles. We want to use a window AC, and we bought a whirpool tub for the bathroom. Here is my plan
3 circuits totally, one for AC, one for whirlpool, the third one for bedroom, bathroom and closet and outdoor. one 3 way switches in stairway to control one light. another 2way switches to control 2 lights in bedroom, one smoker in bedroom. one indoor 2 way switch for outdoor light.3 lights above the mirror in bathroom. exhaust fan in bathroom. one light for closet, serveral receptacles acording to code.
Is is correct to divide the circuit as I said? or is there a better way to divide them?
According to watt, AC, whirlpool both can use 15 amp circuit. the third one use 20 amp circuit. should I all use 20 amp circuits just for safety reason?
