I was thinkin more along the lines of the 2 conductor stuff, not the separate wire. I know it's more expensive but easier for the DIY'er. That's what I used for my garage 3 conductor #6. Can you get that stuff in smaller sizes like #12?

You are on it dave THW-2: Thermoplastic Insulation (usually PVC), Heat Resistant (90C rating), suitable for Wet locations.

THWN-2: Same as THW except Nylon jacket over reduced insulation thickness. Also rated THHN.

THHN: Thermoplastic Insulation (usually PVC), High Heat Resistant (90C rating), dry locations only, Nylon jacket. Also rated THWN.

Key: Suitable for wet locations THWN
Key: Not suitable for wet locations THHN

People think they can run Thhn in coduit in wet locations, but they can't. Unless it has a dual THHN/THWN rating

Great !! I have the 1" conduit's in place and found the THNN/THWN wire from the electrical store (HD and Lowes guy's did not know what THWN stands for).

Do i need to run three of these (12 gauge) wires (red, blue and neutral) in a coduit. How do I color code them ?

#12 wire must be the correct colors - they can't be remarked
In the US I use Black, white & green for a normal run

Hot can be red/black or any othe rcolor EXCEPT white or green
Neutral is usually white, but can be grey
Ground must be green

A 2nd hot for a multi-wire branch circuit I use red
If 2 seperate circuits I might use grey for the 2nd neutral
