I need to wire a new 2nd floor addition. Since I'll have several circuits on the second floor and the (200amp) main panel is in the basement, I'm planning to have a sub-panel on the 2nd floor feed the new circuits. I'm wondering if the following plan makes sense?
Here are the stats:
- 3 bedrooms
- 2 baths (one new one the second floor plus a remodeled bath on the main floor -- I plan to use one dedicated circuit for both baths)
- 1 laundry in second floor bath
- small balcony to include lighting and outlet
- 854 total sq ft (including the main floor bathroom)
For circuits I'm thinking:
- 1 15-amp lighting circuit
- 1 (or 2?) 20-amp circuit(s) for bedroom/office outlets w/AFCI breaker(s)
- 1 20-amp dedicated laundry circuit
- 1 30-amp dryer circuit
- 1 20-amp bathroom circuit (serving 2nd floor & main floor baths)
From a DIY book worksheet, I calculated that I'll need a 60amp breaker, fed via a #6-3 copper cable. Here are the details from the worksheet:
Basic Light/Receptacle Load (854sq ft x 3w): 2562w
Laundry circuit: 1500w
Dryer: 6240w
Outdoor (1 receptacle x 180w): 180w
Gross load: 10482w (total of above)
NEC safety adjustment (10482 x 1.25): 13102.5w
Convert to amps: (13102.5 / 230): 56.97amps (= total load)
Does all of the above make sense?
Thanks.
