MC-Plus / MC-Plus Lite Neutral Per Phase Cable

Galvanized Interlocking Steel and/or Aluminum Armor

Features & Benefits

  • A neutral per phase Type MC cable designed for multi-wire branch circuit applications
  • Addresses harmonics distortions in power distribution systems and meets the requirements of NEC® 210.4(B) Disconnecting Means
  • Eliminates shared neutrals, and allows electrical systems to continue to operate
  • Designed to meet NEC® 210.4(B)
  • Decreases the time it takes to identify a faulty circuit because only the affected single phase breaker will trip thus, reducing the length of unnecessary outages
  • Traditional Type MC cable with a green insulated copper grounding conductor
  • Aluminum armored cables are RoHS compliant
  • Made in USA of US and/or imported materials


Branch circuit wiring for a variety of power distribution systems from lighting, to devices and receptacles. Branch circuit to computers and other electronic equipment where additive harmonics currents from nonlinear switching loads may be present
