The water-resistant symbol with an added "W" signifies that the wire can be used outdoors or in conduit, where THHN cannot. Remember, however, that they are all now combined into one universal wire.
What is the difference between Thhn wire and THWN?
THHN stands for thermoplastic high-heat resistant nylon coated wire. It can be used in dry or damp locations and is rated at a maximum temperature 90AoC (194AoF). The code for THWN-2 is the actual code of the wire. This means it is rated at 90 degrees in both dry and wet locations.

Because the THWN rating is able to resist water, oil and gases, THHN can still be used as a single conductor wire outdoors or in conduit. Installers may find it difficult to run 3-4 single wires. They will need to either run each one separately or tie them together to make them one.
