elecrical layout

i have some questions about the layout for newly constucted master bed and bath.

i drew a crude sketch to be looked at.

the feed comes in from the left

i was considering two circuits. a 15 amp to feed the recepticles and a separate 15 amp to feed the smoke detector then to the lights. maybe it makes more sense to do it a different way? i'm assuming thats too much for one 20 amp. am i allowed to put the bath gfi recepticle at the beginning of the bedroom recepticle run(pigtailed)? i'd appreciate some thoughts/ideas.

The bathroom GFI receptacle must be supplied by a 20 amp circuit.

I would put the bath and bedroom lighting on 1 15 amp circuit along with the smokes.

I would make the bedroom receptacles on a 15 or 20 amp circuit.

All circuits serving the bedroom would need AFCI protection.

As far as receptacle spacing once you enter the room you need a receptacle within 6' of the door. Between receptacles there can be no more than 12' between them. Any wall space 2' or greater requires a receptacle even if behind a door. It looks like you will need to add a receptacle on the stairwell wall as well as the angled wall outside the bath.

If your area has adopted the 2008 Code cycle the receptacles would need to be tamperproof.

Pcboss,

A 'shutter' activated by the inserting prongs will only allow you into the tamperproof recepticle? What is the purpose to this? To keep kids from sticking stuff in there? If so, what makes it so a prong can go in, but not pins and stuff?

Pondering, while waiting. Is it because the shutter will only open up if both slots get pronged at the same time, reducing the likely hood of some kid jamming something into one slot?

The NEC had a change in the 08 cycle mandating the TR receptacles.

I believe they use a shutter like you described but haven't seen one yet.

Here is some info from P&S.

I'd not. I'd put them ( the outdoor recepticals) on their own circuit, or the circuit with the existing outdoor lights. The deck light should be fine on the bedroom lighing circuit.
