Conduit through sill plate under joists?
A while back posted this thread about running conduit in my basement. I haven't made any progress!..LOL
I have 3 big I-beams I have to go around (actually under) to get from one side of the basement to the other. On top of these I-beams however is a 2x8, what I will call a sill plate that the floor joists sit on. Notice in these new pictures that the existing ceiling lines up exactly (or thereabouts) with the sill plates.. If I could drill straight holes through these 2x8 I would not have to bend any conduit at all (otherwise I am looking at 12 90degree bends - 3 beams x 4 bends). Maybe you can make out the sill plates above the I-beams in these pictures (they're all painted the same color)
Is this a bad idea? Is it allowed? Will it affect the structure of the plate? The only catch is that in one section the joists run perpendicular to the plate, so I don't know what I would actually hang the conduit from in that section. Also, if it is possible/allowed/ok how do I drill a hole straight through this 2x8??
