8950705121armored cable (Type AC)An assembly of wires contained within a flexible metallic armor for protection.0
8950705122auxiliary gutterA raceway primarily used to extend or supplement wiring spaces at load centers, transformers, and metering cabinets.1
8950705123back-to-back bendA bend of a length of conduit that results in two 90° bends to produce some form of a U-shape.2
8950705124box offsetA bend of a length of conduit that includes two shallow bends (about 5° each) in opposite directions a short distance apart so that conduit running along a surface can be directed into a knockout hole of an electrical box.3
8950705125buswayA sheet metal enclosure into which conductors are installed at the factory.4
8950705126cable trayAn open cable-supporting assembly used in a variety of commercial and industrial buildings.5
8950705127electrical metallic tubing (EMT)Electrical conduit with relatively thin walls usually made of galvanized steel, though it can be made of aluminum, and can be manually bent with a hand tool. Also called thin-wall conduit.6
8950705128electrical nonmetallic tubing (ENT)Plastic corrugated tubing that provides a flexible electrical conduit. Also called smurf tube because one type of ENT is a bright blue color, like the popular cartoon characters.7
8950705129field bendA bending of conduit done at a construction site (as opposed to a factory bend).8
8950705130flexible metal conduit (FMC)Corrugated metal tubing that functions as flexible electrical conduit.9
8950705131intermediate metal conduit (IMC)Metal conduit with walls thicker than EMT but thinner and lighter than RMC.10
8950705132liquidtight flexible metal conduit (LFMC)Electrical conduit composed of corrugated metal tubing that is covered with a waterproof outer coating and uses special fittings to maintain its watertight integrity.11
8950705133metal-clad cable (Type MC)A heavy-duty commercial and industrial cable that has one or more conductors individually insulated and enclosed in an interlocked metallic armor that consists of corrugated tubing or interlocking tape.12
8950705134multiconductor cableA flexible assembly of conductors that have an overall protective covering.13
8950705135nonmetallic-sheathed cableA cable assembly covered in a nonmetallic sheath and containing of two to four insulated conductors and one bare copper or one green insulated grounding conductor.14
8950705136offset bendA bending of a straight run of conduit to go around some obstruction or to change slightly the plane of the run.15
8950705137rigid metal conduit (RMC)A heavy-wall electrical raceway that is thicker and heavier than intermediate metal conduit (IMC).16
8950705138rigid polyvinyl chloride conduit (Type PVC)A circular, rigid, nonmetallic raceway that uses couplings, connectors, and fittings for joints.17
8950705139saddle bendA bend of conduit using three different offsets to go around an obstruction and then return to the same plane as the rest of the run of conduit.18
8950705140service-entrance cableThe cable used to bring power from the utility pole to the customer's building.19
8950705141shrinkThe amount of length lost along a bend of conduit by adding one or more bends.20
8950705142stub bendA single 90° bend in a length of horizontal conduit used to run to an outlet box.21
8950705143surface racewayA wireway that consists of one- or two-piece channels and easily installed on a surface (rather than being concealed in walls, floors, or ceilings).22
8950705144wirewayA rectangular sheet metal enclosure with a removable cover.23
