Type ___ cable is characterized by a factory assembly of insulated circuit conductors.

Type MC (metal-clad) cable is indeed characterized by a factory assembly of insulated circuit conductors. This type of cable consists of one or more insulated conductors enclosed in a metal sheath, which provides mechanical protection and can also act as a grounding conductor. The insulation of the individual conductors is typically rated for a specific voltage, and the assembly is suitable for a variety of applications, including both residential and industrial settings.

MC cable is designed for use in areas where there may be exposure to physical damage, and its durable sheath allows for installation in ceilings, walls, and exposed locations. The factory assembly aspect ensures that all components are manufactured under controlled conditions, contributing to overall reliability and safety in electrical installations.

In contrast, the other types of cables listed have different constructions and characteristics. For example, NM (non-metallic) cable is a common residential wiring option that does not have a metal sheath and is used primarily in dry locations. SE (service entrance) cable is typically used for bringing power from the utility provider into a building, while AC (armored cable) has a different construction aimed at protecting conductors but does not necessarily signify a factory assembly of insulated conductors like MC cable.
