THHN Cables Used in Control Circuit Wiring

Control circuit wiring is an essential aspect of electrical installations that require the use of cables with high durability and efficiency. Among the top options in this category are the THHN cables, which offer remarkable features that make them ideal for various applications.

THHN Wire Meaning

THHN wire stands for Thermoplastic High Heat-Resistant Nylon-coated wire. This cable has a conductor made of copper, which offers excellent conductivity properties, and a nylon jacket that provides excellent resistance to heat, impact, and moisture. THHN wire is commonly used for indoor and outdoor applications in conduit, cable tray, or raceway systems.

THHN 6 AWG Wire

The 6 AWG THHN wire is ideal for applications that require high amperage and voltage levels. This wire's thickness and copper conductivity make it suitable for use as a feeder cable in commercial and industrial applications. Additionally, it is an ideal choice for motor control centers, automation systems, and other electrical installations that require high current-carrying capacity.

12 AWG Wire THHN

The 12 AWG THHN wire is another popular option for control circuit wiring. It is ideal for applications that require low ampacity levels. This wire's relatively smaller size makes it ideal for use as conductors in branch circuit wiring applications or for industrial control circuits.

THHN Wire Stranded

THHN cables are also available in stranded versions, which feature multiple smaller copper strands twisted together. Stranded THHN wire provides more flexibility compared to the solid wire, making it ideal for use in applications that require cable movement. It is commonly used in control panels, machines, and devices that require moving cables.

THHN THWN-2 Cable

THHN THWN-2 cable is an upgraded version of the standard THHN wire, featuring additional benefits such as added resistance to water & moisture. The "W" in THWN-2 stands for "Water resistant," making it ideal for outdoor applications. This wire's improved properties make it suitable for use in conduit or underground applications that require highly durable and robust wiring.

THHN Solid Wire

THHN solid wire is a popular option for applications that require rigid conductors. Solid THHN wire is composed of a single copper conductor, making it suitable for applications that require permanent installations such as electrical distribution systems, motor controls, and automation systems.

3 AWG THHN Wire

The 3 AWG THHN wire is a thick cable that can handle higher amperage levels. It is ideal for applications that require a high current-carrying capacity such as feeder circuits for commercial and industrial applications. Additionally, it can be used as a branch circuit wiring conductor for large motors and other heavy-duty equipment.
