NANTeL Plant Access and Safety Training Practice Test

A conduit is a protective channel that houses electrical cables, acting like a pipe or tube to shield wires from damage, moisture, dust, and other hazards. In electrical installations, conduits help keep wiring organized, provide physical protection, and make maintenance and inspections easier, while also supporting safety and code compliance. They can be made of metal or plastic and are used in walls, ceilings, and outdoor settings to route circuits safely. The other options describe things that do not protect or carry electrical cables—measuring temperature, powering tools, or protective clothing—so they don’t fit what a conduit is.
