MC Cables Introduction and Application
1.
Introduced in 1960 and used today, Type MC was
the next generation of an interlocked armored
cable assembly. This traditional branch circuit MC
meets UL Standard 1569 and NEC 330. Traditional
Type MC cables consist of copper circuit and
grounding conductors with thermoplastic
insulation (THHN/THWN), an overall polypropylene
assembly tape and an outer galvanized steel or
aluminum interlocked metal armor. Type MC cable
does not have a conductor count limit, offering
various conductor bundle combinations. Type
MC cables of traditional design will include one or
more copper grounding conductors. The armor
of traditional Type MC cables is not an approved
equipment grounding means.
MC-Luminary Quik®, an MCI-A version for ease
of installation with the remove of the insulated
green grounding conductor
2. MC Luminary HCF®, an MCI-A HCF version for
applications that include areas of patient care
3. MC Luminary MultiZone®, a complete line of
multi-zone lighting cable con昀椀gurations
4. MC Luminary® Jacketed, a sunlight & oil resistant
cable that can be direct- buried or trenched in
earth, encased in concrete, or surface mounted.

In 2020, Atkore was the 昀椀rst to commercialize a
Metal Clad (Type MC) Cable with a low-pro昀椀le
interlocked armor design, MC Glide®. MC Glide’s
U.S. patented armor pro昀椀le is designed to reduce
fatigue on workers when pulling cable through
metal studs and ceilings. Installing MC Glide is
smoother, faster, and easier to work with,
reducing the amount of time spent on a job.
In 2004, UL updated 1569 to include Type MC
cables with a ground fault path consisting of an
armor and full-sized bare aluminum ground/
bond wire, known as MCI-A cables (metal-clad
interlocked armor ground cable). These cables
are required to be terminated using connectors
UL listed and identi昀椀ed for MCI-A cables per (UL
514-B). MC-Quik® and MC-Stat® cables are Type
MC designed MCI-A cables. The grounding means
of these Type MC cables is the armor plus the fullsized bare aluminum ground/bond wire. MC-Stat®
also contains a full sized green insulated copper
grounding conductor as required by NEC® 517 for
areas of patient care. Unique to Atkore’s MCI-A
cables, MC-Quik® and MC-Stat® contain insulated
copper circuit conductors with THHN insulation
plus an extruded polypropylene protective
covering versus an overall polypropylene wrap. It
is available in either galvanized steel or aluminum
interlocked armor.
All type MC cables by Atkore, display the
ColorSpec® ID System /Color-Trak for fast cable
and system voltage identi昀椀cation. Type MC cables
should be cut with an armored cable rotary cutting
tool which helps eliminate nicking and cutting of the
conductors and removes the metal armor quickly
and safely.
NEC® is a registered trademark of the National Electrical Code®.
In 2014, Atkore was the 昀椀rst to commercialize
Metal Clad (MC) Cable with both power and
control circuits under one armor, creating MC
Luminary® Cable. UL created a new classi昀椀cation
of MC Cables called MC-PCS (metal clad, power,
control and signal). This new type of cable allows
control/signal conductors to be placed in a cable
with circuit conductors (electric light, power, or
Class 1 circuits per NEC® Section 725.136(I)(1)).
Since then, Atkore has expanded this family of
products to cover additional application:
