What type of wire can be run in conduit?

What is the difference between Thhn wire and THWN wire?

THHN is a code for thermoplastic high heat resistant nylon coated wire which is allowed for use in dry to damp location and rated for a maximum temperature of 90ºC (194ºF). The THWN wire we carry is actually coded THWN-2 indicating its rated 90 degrees for both wet or dry locations which is even better.
