Electrical Raceway Types

A raceway system can be defined just as a track for hiding cables. However, it’s features and functions are much more complex. There is a wide variety of raceways, each suited for a unique application.

Surface mounted raceway (also known as wire raceway or cable raceway) comes in handy in such applications.

Secured to the surface, these raceways have an open face with a removable cover. They are effective when it’s not practical to drill through a concrete block or difficult to remold the existing wires placed inside a wall.

Depending on commercial, industrial, and outdoor applications, you’ll also find a couple more varieties of specialty raceways.


  • Allows adding new wiring to a finished area without requiring drilling through or cutting the surface
  • Makes removal or upgrade of circuits easier
  • Improves the aesthetics of any place by hiding ugly wires

Installation of Electrical Raceways

You have to maintain some rules and regulations for the installation of electrical raceways. Besides, it has to meet the requirements of NEC and NECA “Standard of Installation”.

Electrical RacewaysRaceways have to be installed at the proper elevations, and coordination with other work including metal and concrete deck work is required. However, remember that you have to complete the installation before putting cables or wires within the raceways.

Raceways are suitable for moist or humid atmosphere. So, you can install them in exterior locations, particularly when the wiring is supposed to come in contact with water spray, grease, or dripping oil.

In all the cases, you have to provide secure fastening and support of conduit systems from the building’s structural system. Raceway installation requires professional skills. So, hire a professional electrician or a company for any such project.
