My main panel is outdoors on one end of my house. Planning to add a sub panel for very occasional welder use, electric car charging, and future expansion in the garage on the other side of the house.
By far the easiest path would be outdoors from the main panel along the wall (that side of the house is obscured from view, luckily) up to the attic. Into the house at the attic, across the attic and down the garage wall.
Is it sane to run individual conductors through liquid tight non metallic conduit for this? Would the conduit need to be continuous through the attic? Total run will be about 75 feet. Is there a better solution? I assume 3-3-3-5 SER is not viable since it can't be installed in conduit and I assume this will have to be in the outdoor exposed section.
As a side note, not sure if I can use the 75 degree chart or 60. The wire plus the breaker on the main panel and the connections sub panel determine this? If 75 degree, I could run 4 awg for an 85 degree breaker? That seems adequate. What size ground and conduit? If I have to use 60 degree, I'll go with 3 awg, and I believe 1" conduit and 5 awg ground?
