TL;DR
A raceway is any enclosed channel—conduit, tubing, wireways, or surface-mounted channel—designed expressly to route and protect electrical conductors between boxes and equipment. The NEC treats each type differently, setting fill percentages, support spacing, and where it may run; conductors inside must be derated when too many share one channel.

Surface metal versions such as Wiremold let electricians add circuits across finished walls without opening drywall.
