Wiremold conduit first-timer question
Hi guys, My first posting on here. Looks like a great place to spend a little time & learn. I need to run an exposed circuit & would like to use metal Wiremold for cover. I have researched their site & learned about whats avail. & how to connect it. BUT, what about wire type? This will be a 20A. circuit using 12ga. wire. Is solid THHN what is commonly used OR would stranded be better to fit into places like the 90 deg. corner fittings?
Thanks in advance. I'm sure I'll have more questions as I go here.

Solid and stranded wire can be used interchangeably. Solid works just fine as that is what we use. Stranded would also work, maybe a little better for the corners you mentioned. THHN is the only wire to use in Wiremold. While metal Wiremold is rated as a ground, I suggest running a ground wire anyway.
