Is conduit required for outside outlet?

Hi:
For an outside outlet where the run would come through the basement wall, above ground, then up the outside wall about 18"--

Do I need to use conduit through a hole in concrete block or does code allow outdoor, non-metalic wire?

Thanks a bunch.

You would need to use conduit. Also, don't use regular NM (aka Romex) in the conduit as it is not rated for wet locations, and an outdoor conduit is considered a wet location. Instead, use individual THWN conductors in the conduit. Inside the basement you can run the conduit into a junction box and transition to NM, or just keep running conduit to your power source.

An alternate to running THWN in conduit back to the power source would be to use UF (direct burial rated cable). You could run it from the power source to the conduit as you would run romex, then simply run it through the conduit (the conduit would be to provide physical protection since it is not buried).

Hi:
My local home improvement store had the THWN cable in solid and stranded versions. What are the reasons for choosing one type over the other?
Thanks.

Stranded is easier to pull. Solid is easier to connect.

Stranded bends easier, while solid is easier to connect.
