Carol Bus Drop Cable: 10 AWG Wire Size, 3 Conductors, Gray, Black/Red/White, 250 ft Lg, Unshielded

Bus drop cable is a service cord with multiple insulated conductors that drops down from the ceiling to connect a main power supply to a piece of equipment. It is typically used in manufacturing applications to power stationary equipment or portable equipment and facilitate relocation. It has a durable jacket that is resistant to oil, moisture, and abrasion, so it doesn't need additional protection from conduit or raceways.

Bus drop cable and tray cable are service cords that connect a power supply to a machine or device. They have two or more insulated conductors and a protective jacket that resists abrasion, water, sunlight, and lubricants. Bus drop cable is typically used as a branch connection from a ceiling cable, while tray cable is primarily used for wiring installations in open-air raceways and trays.
