You'll likely see labels like THHN or THWN written on the wire. For example, THHN wire stands for thermoplastic high heat-resistant nylon coated wire. THWN stands for thermoplastic heat- and moisture-resistant nylon coated wire. As you can see, these wires are built to take on many different conditions.
The added W stands for water resistant so that it could be installed outdoors and in conduit when THHN wire could not. However, again, remember that they're all combined into a universal wire now. If you buy THHN wire on our website it will have all of the attributes of each acronym discussed on this page. THW Wire Thermoplastic, Heat and water resistant wire. This acronym is missing the N for nylon coated. The nylon coating looks like the little piece of plastic over a shoe lace and protects the wire in a similar fashion.
