Answer This Question
A: Yes.
The above advice is based upon the current edition of the National Electric Code (NEC). Free access to the latest version of the NEC is available online at www.nfpa.org/freeaccess. The NEC and local building codes regulate the types of wire and cable that can be used in specific electrical applications, as well as the manner of installation. Check your local building codes before you start any wiring and cable electrical project and be sure to obtain required permits. When your work is complete, always have it inspected for compliance with local codes to ensure that it has been safely installed.

I bought both red and black wire spools. I used it to wire my solar panels to the voltage regulator and on to feed juice to the fans and lights on my Gazebo. Everything looks and works great.

I wanted tie wire, not elec. wire. This product is labeled “THHN” which means thermoplastic high-heat-resistant, nylon-coated wire. That’s good to know if you want it for electric stuff.
