The Wiremold Company introduced the Wiremold raceway in June 1916 as a lightweight, molded metal conduit designed for installation on walls, ceilings, and baseboards. This product aimed to address the lack of electrical outlets in American households, which struggled to keep up with the increasing number of electric products. While Wiremold offers various power solutions, it is unclear if it acts as an electrical shield. Some sources suggest that it can be used for grounding if listed for that purpose, but specific details are unavailable. Further research is needed to determine if Wiremold acts as an electrical shield and under what conditions.

What You'll Learn
Wiremold as EGC
There is some ambiguity over whether Wiremold can be used as an EGC. Some electrical professionals have stated that they have always used an EGC wire in Wiremold, but others are unsure whether Wiremold falls into the category of EGC.
According to one source, if the wireway is complete all the way to the source and the connectors and couplings are tight, then it is allowed as an EGC. However, another source notes that by NEC rule, a raceway must be listed as an equipment ground to be used as such, and they do not believe Wiremold is listed as a ground.
It is worth noting that some professionals have expressed trust in Wiremold to pass an EGC better than a cord cap, especially 5-15/20 or 6-15/20's.
Overall, while there is some uncertainty, it appears that Wiremold can be used as an EGC under certain conditions, such as when listed for grounding and when transitioning to another wiring method that is also listed/permitted to be used as an EGC.

Wiremold raceway
Legrand raceway solutions, including Wiremold, have been the industry-leading cable raceway solution for nearly a century. They provide an attractive, cost-effective, and hassle-free way to route power and data. Wiremold offers a wide array of power solutions for public spaces, both indoor and outdoor.
While Wiremold does not appear to be listed specifically as an EGC in the NEC, electrical professionals have used it as such, as long as wire EGCs are properly terminated to it in boxes. It is also noted that if Wiremold is listed for grounding, it can be used for grounding, but if you transition to another raceway, a means to connect an equipment grounding conductor is necessary.
In terms of its shielding capabilities, while I could not find direct confirmation, the fact that Wiremold is used for routing power and data, and is trusted by electrical professionals for grounding, suggests that it does provide some level of electrical shielding.
Overall, Wiremold raceway is a versatile and trusted solution for cable management and routing power and data, with applications in various markets, including commercial, residential, healthcare, and education.

Wiremold for outdoor spaces
Wiremold is a cable management system used to conceal and protect electrical wires and cables. It is commonly used in commercial and residential buildings to organise and route electrical wiring in a safe and efficient manner. While Wiremold is typically rated for indoor use only, it can be used outdoors in certain situations.
When using Wiremold outdoors, it is important to consider the environment and follow the manufacturer's instructions and safety guidelines. For example, Wiremold should not be exposed to the elements, such as rain, snow, or direct sunlight, as this could cause corrosion or short-circuiting. If you need to route cables or wires outside, you should use weatherproof boxes or cable management products specifically designed for outdoor use, such as weatherproof conduit or cable trays.
In some cases, Wiremold can be used outdoors if it is used in tight spaces or where flexibility is required. For example, if you are unable to access the underside of a deck to run wires, you may be able to use Wiremold to create a more aesthetically pleasing installation. However, it is important to note that Wiremold will rust if exposed to the elements, so it may not be the best choice for outdoor spaces.
One way to use Wiremold outdoors is to slide the back out of it, so it becomes an open-back steel cover for the NMB, UF, or other wiring. This type of installation can provide protection from physical damage and dress up the installation while still being compliant with safety regulations. However, it is always recommended to consult with a qualified electrician or cable management specialist to ensure that you are using the most appropriate products for your specific needs and environmental conditions.

Wiremold for indoor spaces
Wiremold is a highly versatile product that can be used for indoor and outdoor applications. It is a popular choice for wire and cable management, offering a wide range of power solutions for public spaces.
For indoor spaces, Wiremold provides an effective way to manage cables and power outlets. It can be used to create a neat and organised appearance, hiding unsightly wires and cables. Wiremold products are available in various colours and styles to blend in with different interior designs. For example, the 700 Series White Raceway Electrical Box and the 10-Outlet Off-White Power Strip are designed to seamlessly blend in with interior walls and surfaces.
Wiremold is particularly useful for remodelling projects or building new rooms in basements or add-ons. It can be used to add overhead lights, track lighting, and power outlets in game rooms or basements. It is also beneficial for managing cables and providing power in home offices or entertainment areas.
Additionally, Wiremold can be used to enhance the functionality of indoor spaces by providing convenient access to electric vehicle charging. This feature is especially useful for indoor parking areas or garages, allowing electric vehicle owners to charge their cars safely and efficiently.
While Wiremold is primarily used for cable management and power distribution, there is some discussion among electrical professionals about its role as an equipment grounding conductor (EGC). Some professionals suggest that Wiremold can be used as an EGC if it is listed for grounding and properly terminated. However, others are unsure if Wiremold falls into this category, and specific guidelines may vary based on location and wiring regulations.
