Check with your local Authority Having Jurisdiction (AHJ) for local code compliance.
Q: What are the liquditight flexible metal conduit specifications?
A: Each AFC Liquid-Tuff Liquidtight Flexible Metal Conduit type is designed to comply with applicable NEC and/or CSA codes for the intended application.
For more information take a look at AFC Cable’s Liquidtight conduit.
Q: What is an AC Cable?
A: Armored Cable is an alternative to traditional pipe and wire electrical installations. Armored cable wraps the insulated copper conductors individually with paper within a metal sheath.
Armored cable is manufactured to UL® standard UL® 4 and is limited to four phases and neutral conductors with size limitations of 14 AWG to 1 AWG and contain a 16 AWG bare aluminum bond wire to be used in conjunction with the armor as a ground path.
Q: What is an MC Cable?
A: Traditional MC Cables have a THHN/THWN insulated copper conductor with polypropylene wrap and are designed to meet UL® 1569 standards. Metal Clad Cable or MC Cable will have one or more grounding conductors.
Q: What is the difference between MC Cable and AC Cable?
A: Major differences between Type AC and MC are the trade size. AC Cables range from 14 AWG through 1AWG, whereas MC Cables can range from 18 AWG through large feeder size cables.
AC Cables have insulated conductors that are wrapped with a moisture resistant, fire retardant Kraft paper whereas MC Cables come with an overall polypropylene wrap.
Another difference between the two cable types is the ground path. AC uses a bare aluminum bond wire plus the armor as the ground path, Traditional Type MC Cables utilize a green insulated grounding conductor and the armor is not an approved grounding means.
AFC offers MC-Quik® which utilizes a full size bare aluminum bond wire with the armor as an approved grounding means. AFC also offers both AC and MC cables in steel and aluminum.

Q: How do I cut MC Cable?
A: The proper method for cutting MC Cable is to use a rotary cutting tool specifically designed for use with Interlocked MC Cable.
Q: What is flexible conduit?
A: Flexible conduits are intended for use as an alternative to traditional pipe conduit. Unlike pipe, there is no need to bend the conduit to fit around corners. It is also used where flexibility is required and where vibration or movement of equipment is necessary
Q: What are the different types of flexible conduit?
A: Flexible conduits is available in liquidtight, which can be metallic or nonmetallic, and also flexible metal conduit. Liquidtight comes in numerous types to meet multiple applications including high temperature, splash zones, Low smoke-zero halogen, etc. Flexible metal conduit comes in a range of configurations including aluminum and steel varieties.
Q: What are the different flexible metal conduit sizes?
Liquidtight and flexible metal conduit have size ranges from 3/8″ up to 4″ depending on the application.
Q: What are the different connector types?
A: Connectors and fittings come in various types, sizes and configurations to meet the many size and application ranges.
For more information look at our AFC Fittings.
Q: What is Type MCI-A Cable?
A: Type MCI-A Cable refers to Metal-Clad Interlocking Armor Ground Cable Type. Unlike traditional Type MC Cable, MCI-A cables utilize the armor plus a full-sized aluminum ground wire as the equipment grounding means.
AFC’s MC-Quik® MCI-A Cables are available in either interlocking galvanized steel or aluminum armor. MC-Stat® MCI-A cable has a full-sized insulated copper conductor as a second equipment grounding means for healthcare applications.
Q: What is MC-PCS?
A: Type MC-PCS cable stands for Metal Clad Cable – Power Control Signal. These are Metal Clad cables that contain traditional copper conductors for power, along with a jacketed twisted pair used for control wiring that is used in dimming systems. Traditional installation uses a power cable along with separate wiring for the dimmer. Combining both under one armor reduces labor and installation costs.
