MC Cable advantage Using Type MC cable, contractors can install multiple conductors with professional-looking, owner- satisfying appearance in less time than it takes to hang empty conduit. MC cable delivers up to four conductors up to 1000 kcmil plus a ground wire in a tough, flexible aluminum armor. MC cable puts an entire 600V feeder circuit into a single, rapid-installation assembly, and it’s National Electrical Code ® (NEC)-compliant for high-rise buildings, assembly halls and many hazardous locations. ReduCed installation steps The biggest advantage of MC cable over conduit-and-wire installations is the reduction in time and labor to achieve neat, workmanlike appearance, code compliance and owner satisfaction. A typical MC cable installation requires only five steps, where comparable conduit applications require 14. MC reduces overall installed costs by roughly 30-50% when compared to pipe-and-wire systems. unliMited 90-degRee bends Pipe and wire installations require a pull box or junction box after every fourth 90° bend (total of 360 degrees of bends). MC cables aren’t limited by that restriction. MC eliminates the need for junction boxes between pull points, and also the need for large pipe benders on the job. FaCtoRy Ry R tested asse asseMblies With conduit installations, the vast majority of insulation damage happens during installation. MC cable assemblies are factory tested before leaving the plant, and conductors are fully protected inside the armor during shipping and installation. That greatly reduces the potential for damaged conductors in the finished job. ReduCed waste Southwire can provide custom-cut lengths of MC cable including very long runs. Using custom-cut lengths can significantly reduce waste on the jobsite. (With longer runs, contractors must have the equipment necessary to move and install the cable.)

Purpose of this Guide This guide provides engineers and contractors with essential information on the basic applications, selection, and installation of MC feeder cables. Electrical contractors have used smaller MC cables for branch circuits for many years. The industry is now converting to larger MC feeders. These large cables offer the owners and contractor the same advantages as found with the smaller MC branch circuits. These MC feeders are now being used in most types of commercial construction, including apartments, condominiums, hotels, stadiums and office buildings. MC feeders provide a neat and orderly appearance, alternative to pipe and wire. This guide should address most concerns about handling and installing these large MC feeders.
