10/3 Bus Drop Cable is an industrial-grade power distribution cable designed for connecting overhead busways to stationary or semi-stationary industrial equipment. It provides reliable, flexible 600V power in environments like factories, machine shops, and manufacturing facilities, offering a removable electrical connection without disrupting plant power.
In 10/3 Bus Drop Cable, the "10" refers to the 10 AWG size of the three primary power phase conductors. The "3" indicates that there are three insulated power conductors inside the assembly (Black, White, Red). Additionally, this cable includes three uninsulated 14 AWG bare copper grounding wires cabled into the assembly for equipment grounding.
Featuring three separate 14 AWG bare copper grounds rather than a single large ground is a key engineering trait of bus drop cable. Symmetry around the active phase conductors makes the overall cable rounder, more flexible, and easier to suspend. It also helps balance induced currents and improves fault-to-ground path protection across the assembly.
While both are rated for 600V in demanding industrial plants, Bus Drop Cable is specifically engineered for stationary or semi-stationary overhead drops supported by strain-relief grips. SOOW cables are designed for general-purpose portable power and continuous flexing applications (like hand tools or portable machinery). Bus Drop Cable should not be used for continuous flexing or portable equipment.
Yes! The heavy-duty gray PVC outer jacket is specifically formulated to be 60°C oil-resistant, UL listed for outdoor weather exposure, and suitable for use in Class I, Division 2 hazardous locations.
