Raceway: what it means for the Texas exam

Bonding Jumper editorial teamSources checked 3 min read

A raceway is an enclosed channel, made of metal or nonmetallic material, designed specifically to hold wires, cables or busbars. Conduit, electrical metallic tubing, flexible conduit and wireways are raceways. The conductors are pulled into the raceway after it is installed, and the raceway protects them and can be opened up or rewired later.

Four short sections drawn side by side: rigid conduit, EMT with a set-screw coupling, flexible metal conduit and a rectangular wireway, all labeled raceway, and to the right a cable with its own jacket, labeled not a raceway
A raceway is the enclosure. Cable carries its own jacket.

Common raceway types

  • Rigid metal conduit and intermediate metal conduit: threaded, heavy-wall steel or aluminum, for the most physical protection.
  • Electrical metallic tubing: thin-wall steel joined with set-screw or compression fittings; a widely used raceway.
  • Rigid PVC conduit: nonmetallic, resistant to corrosion, common underground.
  • Flexible metal conduit and liquidtight flexible conduit: for connections to motors and vibrating equipment.
  • Wireways and surface raceways: troughs with removable covers.

Each type has its own NEC article covering where it may be used, how it is supported and how many bends are allowed between pull points.

What does not count

  • Cable. Nonmetallic-sheathed cable and metal-clad cable have their own jacket or armor around factory-installed conductors. They are cable assemblies, not raceways.

The easy way to tell them apart is to ask where the conductors come from. In a raceway you pull separate conductors in after the enclosure is up. In a cable they arrive already assembled inside their own covering.

Why the distinction matters

Several rules apply only to raceways, and several apply only to cables. Conduit fill, the share of a raceway's cross-section conductors may take, uses the Chapter 9 tables. A metal raceway can serve as the equipment grounding conductor under Article 250 when its fittings keep it continuous; see EGC vs GEC. The conductor insulation types you pull in depend on whether the raceway is in a wet location, and the raceway ends in boxes whose box fill you must check.

Common mix-ups

  • Calling MC cable a raceway. Its armor is part of the cable.
  • Assuming PVC can be the ground path. A nonmetallic raceway needs a separate equipment grounding conductor.
  • Forgetting that underground raceways are wet locations inside, so the conductors must be rated for wet use.

On the Texas journeyman exam

Raceways sit in wiring methods and materials, 12 scored items across both portions under the PSI bulletin. Study to find where a raceway type may be used, how it is supported, and how many conductors fit.

Practice it

The conduit fill guide walks through the Chapter 9 tables and Annex C. Every term in this set is in the electrical terms glossary.
