Last night I managed to get the first round of ENT conduit and the electrical boxes installed and in place in the perimeter walls of the porch. No wire pulls, but the routing is gentle enough that pulling 12/2 should be relatively hassle-free.

I still have to figure out routing for the interior lights. I was looking at it last night and I think I have a pretty good idea where to go, but there's still a bit of a narf from where the wiring comes through the basement wall into the porch and then back into the house wall cavity. I might actually do a separate hole for the lighting conduit since I think I can route it into the wall cavity much easier that way.

Incidentally, color codes for utilities from the APWA listed below:

Red	electric power lines, cables, conduit, and lighting cables
Orange	telecommunication, alarm or signal lines, cables, or conduit
Yellow	natural gas, oil, steam, petroleum, or other gaseous or flammable material
Green	sewers and drain lines
Blue	potable drinking water
Violet	reclaimed water, irrigation, and slurry lines
Pink	temporary survey markings, unknown/unidentified facilities
White	proposed excavation limits or route

Good to know.

Weird thing: the smurf tube is blue, as are the PVC electrical boxes.
