Underground pull

[rgconway]

Hello all, I've been reading this forum with great interest and decided to post a question. I'm an engineer and DIY homeowner doing my first outbuilding. I have 50' of 1-1/2" sch 40 PVC buried. There is a 90* coming up from the trench and two 45* in the run, rest is straight. I'd like to pull 100A and, with derating, think I need 2ga copper. I'd also like to pull two 3-way switch legs. So, I think I need three 2ga THWN-2, one 8ga for ground, six 14ga for switches and a shared ground wire. Although this adds to ~27% conduit fill, I wonder how difficult. I can get a good pull at the straight foundation penetration, but this means pull the full length through the 90* Sorry if novice question, any thoughts appreciated. Thanks.

Bob
