How many watts for the floodlights. Really high powered tungsten halogen lights would probably mean you need a separate circuit for the three of them.
That is false. A 20 amp circuit can be loaded to 20 amps. The 80% rating is for continuous loads of 3 hours or more.Per NEC you can only load a circuit to 80% which comes out 1920 watts.
Which is 16 amps
3- 300 watts lights equals 7.5 amps.
Since yiu know how many outlets you are adding, than load calc is 2 outlets x 180 va= 360 / 120- 3 amps
3 +7.5= 10.5 amps
You will be fine.
Hmm excellent question! I haven't really thought about having the receptacles on a switch. If I do have switches I'll have one for each of the two receptacles.Are you running power to the switches first or the receptacles? How many switches? Will the receptacles always be on or switch controlled?
I might suggest you read "Wiring Simplified" so you can see some wiring methods.
Is the crawl space dry and sealed up with a concrete floor?Now I have my 12/2 wire in the crawl space towards the back and there's not much slack. So I think I need a junction box right by that 12/2 wire which allow me to run the actual wire to the front of the house.
What type of junction box?
what type of wire?
I'm going through brick, what do I need to do here?
Dry, yes, but it has a dirt floor. Probably best not to chance it thoughIs the crawl space dry and sealed up with a concrete floor?
Since you said the crawlspace is dry you could run NM-B and use plastic nail-on boxes with blank covers. Drill a 1/2" hole thru the brick and come into the back of a weatherproof box. You will need to chip out the brick face for the connector that gets screwed into the back of the box. Caulk the top and sides of the box to the brick. Install a weather-resistant GFI and a weatherproof in use bubble cover.
This would be a more common box, but the other is fine.I can use a box like so?

Do I need to run my NM-B wire through PVC or is drilling through the joists and running it ok?
Looks good. UF is a waste of money here IMO. PITA to strip also. Only 1 cable per clamp, box fill appliesMakes sense --- here's what I got so far.

I think I'm going to go with the UF cable just for some added piece of mind.

Also the junction box (for lack of a better word) can accommodate multiple UF connections if I wanted to maybe add another outlet in the back of the house?
