Thhn Cable Rating

By | August 14, 2022



The THHN cable rating is a term that expresses the maximum current and voltage capability of a particular type of electrical cable. It stands for Thermoplastic High Heat-Resistant Nylon and is a popular choice for many electrical wiring projects because it is affordable, durable and can be used in numerous applications. THHN cables are also known as THW cables.

When it comes to THHN cable ratings, the current and voltage ratings are the most important factors to consider. The current rating of a cable is the amount of electricity, measured in amps, that can flow through the cable safely without causing damage or sparking. The voltage rating of the cable expresses the maximum amount of voltage that the cable should be exposed to.

The THHN cable rating is designed to meet stringent safety standards and ensure that electrical projects won’t be vulnerable to shock or fire hazards. Wiring with the wrong gauge of cable, or one that is not rated correctly can result in damage to electrical components, cause fires, or result in shocks to humans and animals. However, with the right THHN cable rating, you can be confident that your project will be safe and successful.
