Happy to help! I actually misremembered - my conduit is also 3/4", not 1" like I thought. So if I can run 60A/240V through mine, so can you. If you wanted to save some $, you could do 8GA RW90 to get 40A/240V service for really cheap. Add a cheap subpanel and you'd be good to go.This quote is hidden because you are ignoring this member.

Southwire has a handy conduit fill calculator you can use, your PVC is likely Sched40 and wire thicknesses are available for anything Southwire makes. Other manufacturers may have slightly different specs but it'll be within a few %.
I found that buying locally, TWN 6GA was actually noticeably cheaper than 8GA because wholesalers will cut 6GA for you to length, but will only sell 8GA in 300m spools. I ordered my TWN 6GA conductors from Electrical Wholesalers but had to go through Lowes for my TWN 8GA ground wire, which per-foot was more expensive than the 6GA. I think 8GA RW90 was the cheapest but you'll have to check on that.
