Pole loading load cases 1

[gwillis33]

When doing a pole load calculation (ie nett load on pole due to conductor loads) what are common load cases you'd look at? eg no wind @ 60deg, wind/ice @ 0 deg etc?
Thanks.

It depends on the place you're doing the project. In the US, NESC defines three different zones: Light loading, Medium loading and Heavy loading. Light loading - 0" ice, 4psf wind, Medium loading - 1/4" ice, 4psf wind, Heavy loading - 1/2" ice, 4psf wind. You can find the NESC zones map in NESC book 2012 edition or a Google search might help you figure out which loading zone your current work falls under.

Thanks engratcorner. Let's say you are in the heavy loading zone. Would you examine pole loading under the heavy load case, and also under a no wind case?
