I. Cable Wiring MethodsArmored Cable (Type AC)- a fabricated assembly of insulated conductors in a flexible metallic enclosure. Also known as BX Cable

I. Cable Wiring MethodsMetal Clad Cable (Type MC)- a factory assembly of one or more conductors, each individually insulated and enclosed in a metallic sheath of interlocking tape, or a smooth or corrugated metallic tube.

I. Cable Wiring MethodsHow can I tell the difference between Armored Cable and Metal-Clad cable, since they both have the same outside appearance? – Type AC cable will always have a 16 AWG aluminum bond wire under the armor, and the individual insulated conductors will each have a kraft paper wrap. Type MC cable does not contain either of these items and has an overall plastic wrap over the insulated circuit conductors

I. Cable Wiring MethodsMineral Insulated, Metal

Sheathed Cable (Type MI)

- a factory assembly of one or more

conductors, insulated with a highly

compressed refractory mineral and enclosed in

liquidtight and gastight continuous copper or

alloy steel sheath.

Nonmetallic- sheathed Cable (Type NM & NMC) - a factory assembly of two or more insulated conductors having an outer sheath of moisture- resistance, flame- retardant, nonmetallic metal- commonly used in One and Two family dwelling, but cannot be used in structures exceeding three floors.

I. Cable Wiring MethodsShielded Nonmetallic

Sheathed Cable (Type SNM)- a factory assembly of two

or more insulated conductors, in an extruded core of moisture-resistant,

flame-resistant nonmetallic material, covered with an

overlapping spiral metal tape and wire shield and jacketed

with an extruded moisture, flame, oil, corrosion, fungus

and sunlight resistant nonmetallic material.
