What is an AC 90 cable?

AC90 is a flexible interlocked aluminum armoured cable approved for use in open and concealed wiring in dry locations. AC90 is a cost effective alternative to conduit wiring. AC90 eliminates the need for conduit, fittings and the labour associated with pulling in wire, threading, and forming conduit.

What is armored cable AC?

Armored cable, referred to as Type AC cable or BX Electrical Cable is one of the original styles of flexible conduit used as an alternative to pipe and wire installations. These cables are manufactured to the UL® 4 standard. AC Cable can be used in a variety of applications per NEC Code.

Can I use armored cable instead of conduit?

Type MC armored cable can be installed in cable tray, racks, hangers, or as a cost-effective replacement for conduit and wire where specified per the National Electrical Code (NEC).

Is AC90 the same as BX?

AC90 (Bx) Armoured Cable Wiring: BX is used primarily in commercial buildings. Aside from NMD90, BX is probably the next most commonly used cable in the electrical industry. AC90 has an FT6 fire rating and is permitted to be installed within spaces being used as a return air plenum.

What is the difference between Type AC 90 and Type Teck 90 cable?

-ACWU contains aluminum conductors, whereas Teck has copper conductors. Teck also has an inner PVC jacket (under the armour, over the conductors) in addition to the outer one, whereas ACWU only has the outer one. Both have interlocking armour. -RA90 is PVC jacketed aluminum sheathed cable.

Can you use AC 90 outside?

There is armored cable and there is flexible metallic conduit. In some instances the flexible metallic conduit can be exposed to weather but it requires special insulation on the conductors. No, you cannot use this cable outdoors.

What is the difference between MC and AC cable?

The biggest difference between the two cable systems is that MC has full size ground wire while AC uses a combination of the jacket and a thin bonding strip or wire to function as the equipment ground.

What does HCF cable stand for?

The hospital grade AC cable is the second variety of flexible armored cable developed by AFC called HCF.

What is the difference between Romex and BX?

Romex is one popular brand of NM electrical cable. A chief distinction between BX and NM is that BX can achieve grounding through the outer metal casing. This casing needs to be attached to metal boxes. Another distinction is that some types of BX cable can be installed in exposed locations, either indoors or outdoors.

What is the difference between Romex and MC cable?

Romex is called NMB (non metallic is the generic name) in the code. BX is a MC (metal clad) cable. There is also a AC, or armored cable. AC’s cladding can be used as the ground, it also has a bonding strip which helps with using the jacket as a ground, where as MC will have a separate green ground wire.

Is BX cable legal?

BX is accepted by the National Electrical Code (NEC). Older BX cables without an internal bonding strip are not accepted by NEC. NM cable is also accepted by the NEC.

Why is it called BX?

Armored cable (AC) first appears in the 1903 NEC. There were originally two initial versions of armored cable. One was called “AX” and the other “BX,” with the “X” standing for “experimental.” The “BX” version became the one that eventually was produced, and hence the name “BX” became the common name.

Is the AC 90 steel cable painted black?

AFC Cable’s AC 90 ® Steel armored cable has circuit colors painted on the armor as well as the cable is painted black for easy identification during and after installation. Commercial, industrial, multi-residential branch circuits and feeder wiring, services for power, lighting, control and signal circuits.

What kind of cable is AC90 ISO aluminum?

Inc., proudly introduces AFC Cable Systems AC90 and AC90 ISO aluminum armoured cable to the Canadian Market. AC90 construction provides mechanical protection of electrical conductors, allowing for bending around corners and fishing through walls of existing construction.

What kind of conductor does a C90 armoured cable use?

What are the different types of armored cable?

Other armored cable types such as MC Cable utilize green insulated grounding conductors. In addition, Type AC armored cable is insulated with a moisture resistant paper wrap, MC cables are insulated with polypropylene wrap.
