In the US you use PVC for outdoor installations, and steel conduit for indoor... with some exceptions that I'm sure someone will be quick to lambast me for.

- quickthrowman 2y agoI won’t lambast you, but I’ll correct you ;) PVC conduit is used for some underground applications, it isn’t (typically) used outdoors above ground since UV light destroys it. You can use EMT w/ raintight compression fittings or galvanized RMC outdoors (or PVC-coated RMC if you have lots of money and/or want it to last 50 years). Steel conduit (or metal-clad cable) is typical for indoor commercial installations, aside from some specific places where aluminum or PVC is used, like an MRI room.
