What Is Wiremolding?


Wiremolding is a type of cable management system that is used to conceal and protect electrical wires and cables. The technical / code name for this product is a “surface metal raceway” and raceway is a more technical term used in the construction industry. It is a modular system that consists of a base, cover, and fittings that can be easily assembled and installed onto walls, ceilings, or floors. Wiremolding is commonly used in commercial and residential buildings to organize and route electrical wiring in a safe and efficient manner. It can be made of various materials including metal, plastic, or PVC and comes in a variety of sizes and shapes to accommodate different types of cables and wiring.

The system is designed to be aesthetically pleasing, with the ability to be painted or finished to match the surrounding wall or surface. It is also easy to access, allowing for quick maintenance and repairs when needed. Overall, wiremolding is a useful solution for managing and protecting electrical wiring in both commercial and residential settings.



Is Wiremolding Allowed for Exterior Locations?

Wiremolding is not designed for outdoor use and should not be used in areas exposed to the elements, such as rain, snow, or direct sunlight. Wiremold products are typically rated for indoor use only and do not have the necessary protection to withstand outdoor conditions. Doing so could expose the interior cable wiring to moisture and cause corrosion or short-circuiting, as well as accellerate wear and tear on the equipment. This can even become an electrical shock hazard.

If you need to route cables or wires outside, you should use cable management products specifically designed for outdoor use, such as weatherproof conduit or cable trays. These products are designed to provide protection from the elements and can help prevent damage to the cables or wires.


What Type of Electrical Conduit is Rated for Exterior Use?

There are several types of electrical conduit products that are safe for exterior use. The type of conduit you choose will depend on your specific needs and the environmental conditions that the conduit will be exposed to. Some common types of electrical conduit products that are designed for outdoor use include:

  • Rigid Metal Conduit (RMC): RMC is a heavy-duty conduit made from steel, which makes it extremely durable and able to withstand harsh weather conditions. It is often used in industrial and commercial applications and is suitable for outdoor use.

  • Intermediate Metal Conduit (IMC): IMC is a lighter-weight version of RMC, also made from steel. It is a good choice for outdoor use where the conduit needs to be installed in areas with high levels of vibration or movement.

  • PVC Conduit: PVC conduit is a lightweight and cost-effective option for outdoor use. It is resistant to corrosion, moisture, and UV rays and can be used in a variety of applications.

  • Liquidtight Flexible Non-Metallic Conduit (LFNC): LFNC is a flexible conduit that is resistant to moisture and UV rays. It is a good choice for outdoor use in areas where the conduit needs to be installed in tight spaces or where flexibility is required.

It’s important to follow the manufacturer’s instructions and safety guidelines when installing cable management systems. If you’re unsure about which type of cable management system to use for your particular application, you may want to consult with a qualified electrician or cable management specialist to ensure that you’re using the most appropriate product for your needs.
