nothing jumps out at me. Remember that you are allowed to load a circuit to 80% of its rating. Nice diagram, what software did you use?

and some google images.Thanks for the 80% info, I'll have to do some math to see if I'm over the limit. Can always use smaller lights for the outside, but I like the 150W bulbs to let me know if they go off.

Nope.
EDIT: 80% is 1440 watts, you're not even close.

Make sure the cover on your junction box is accessable (not covered by any finish material). This is required by code.

Can it be in accessable attic space, above the insulation level?

That's fine.

I don't think so, the top of the panel is usually eye level when standing. Also, you're supposed to have 3' clear space in front of the panel.

Just to clarify, we are talking about the junction box here not the service panel.
Yes, I believe this is acceptable but I am not an electrician by trade. I'm sure Charles will weigh in on this at some point and he knows code requirements much better than I.

I was referring to the junction box as well.

I just thought stang may have been thinking about the service panel.

There are lots of junction boxes in lots of attics. I don't recall anything in the code other than the fact that the box does have to be accessable and not covered up. If the attic is accessable thru a scuttle or stairs, then that is probably just fine.
Remember, I'm not a licensed electrician, I just keep reading the code over and over, along with everything else I can find that is related.

Thanks everyone for the info! Great stuff.
I've the four cans already ran, and working on the two outside lights runs.
Talking of junction boxes in lots of attics.... I've another run, in my house, I'd like to tap into, however it's not close to an access spot. Unless I do a box on the ceiling. is this ok?
(Yeah I look into the code, but figure good pratic is good)

You can put j-boxes anywhere you like as long as you don't cover them up with drywall, plywood, cabinets, etc. Even if you have to climb clear across your attic to get to them, it's still legal. I try to avoid attic boxes as much as possible and would rather fish wires down the wall to the nearest recep or switch box. This avoids having to climb in the attic in the future for troubleshooting. Another option that's common in older houses is to tap into a light fixture box where power is brought there first and then taken down to the switch.
Mr.N said:
The 2 travelers (the red and black wires between the 3-way switches) should be connected to the same screw on each switch. Corrected drawing below. Only much smaller.
If the single switch and one of the 3 way switches are going to be in the same room, why not put them together in a double box and use that as the junction box, too? No need to go to attic then.
