Can I use MC Cable over BX cable?
BX cable is more expensive than NM cable. NM cable tends to run about 25 percent cheaper than BX cable as it ships lighter and uses fewer source materials. Handling. BX is heavy and difficult to run through studs. Not only is NM cable light, but the slippery coating makes the cable easy to pull through holes in studs.

What is the difference between AC vs. MC Cable?
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.
What is the difference between armored cable and MC Cable?
- 600 V
- 2000 V
- 2.4 kV to 35 kV Medium Voltage (MV)
- Composite cables that include optical-fiber members (OF)
Is MC and BX cable the same?
For those who are not familiar with the difference between the two, BX has a mechanical ground as part of the armored cable wall or jacket, where MC has an "extra" green wire that is used for grounding purposes.
Is BX a MC?
Going under alternative names such as metallic sheathed cable, type AC, MC, Greenfield, or armored cable, BX cable is a collection of plastic-coated insulated wires (typically 14- or 12-gauge), bundled together and protected by a ribbon-like metal sheathing.
What does BX wire stand for?
Apr 7, 2006. Per Jim Dollins, VP of Product Development for AFC Cable Systems, the term "BX" stands for "Product "B" - Experimental." Apparently, back when the product was first developed, the first manufacturer of this product had only one product at the time: "Product "A"".
What is the difference between armored cable and MC cable?
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.
Can BX cable be used as ground?
Most BX is neither safe or acceptable for use as an equipment grounding conductor. Only BX which includes a bonding wire or bonding strip may be used as ground.
Is BX cable still used?
Our house was built in 1905 and while a lot of the electric has been replaced throughout the its 115 year life, a lot of the old BX cable (likely original or close to it) is still in use; mostly for lamps, lights, general use outlets (non-heavy duty).
Can you use BX in residential?
Today, residential construction primarily uses three types of wiring, Non-Metallic (NM) cable being the most common; followed by BX (also know as Armor Clad, or Flexible Metal Conduit), and individual conductors run inside conduit.
Can you use MC cable in a garage?
Can MC cable (14-2) be used to wire a residential garage? Article 330 says it can be used as open runs of cable not subject to physical damage. Rather than fish wires through walls, the MC cable would be run exposed to supply electrical outlets. Also, there is no seperate ground wire, just the bonding wire.
Is MC cable better than Romex?
Safety: Compared to Romex, MC cable is safer to install due to its metallic sheath. This sheath helps protect against accidental shearing and penetration, reducing the risk for accidental wire exposure. Romex sheathing is easily penetrated or sheared, making it less safe unless run through protective conduit.
Is MC cable suitable for outdoor use?
Type MC Cable without an outside nonmetallic jacket can be installed in an “other space used for environmental air” in accordance with Section 300.22(C). These cables can be installed either indoors or outdoors and in exposed and concealed locations. They can be direct buried, where identified for such use.
What is the difference between Romex and BX?
Romex cables are light and have a slippery coating that easily pulls through holes. BX cables are safer and protect against any accidental penetrations. Romex cables have vinyl sheathing that you can penetrate easily. A BX cable usually is grounded through an internal plastic-coated ground wire or metal armor.
Is BX wire copper or aluminum?
BX Cable / AC Lite Aluminum Armored Cable - UL and RoHS Compliant.
What is a BX connector?
Use: BX connectors are used to terminate steel Armored. Cable to a 1/2" knock-out in a dry. location box or enclosure.
Power Cable
Power cables are mainly used for power transmission and distribution purpose. It is an assembly of one or more individually insulated electrical conductors, usually held together with an overall sheath. The assembly is used for transmission and distribution of electrical power.
Bare Overhead Conductor
Bare Overhead Conductors are used in overhead transmission and distribution network applications.They are also used for un-insulated hook ups, jumpers, grounding conductors and other applications.
Aerial Bundled Cable
Aerial bundled cables (also aerial bundled conductors or simply ABC) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. Our abc calbe conform to ASTM, IEC, SANS standards.……Including: abc cables, cvered line wire, service drop wire etc.

What is BX cable?
What Are BX Cable and Wire? Going under alternative names such as metallic sheathed cable, type AC, MC, Greenfield, or armored cable, BX cable is a collection of plastic-coated insulated wires (typically 14- or 12-gauge), bundled together and protected by a ribbon-like metal sheathing.
When was BX cable invented?
BX is one of the earliest types of electrical cable developed for both residential and commercial uses in the early part of the 20th century. Forms of BX can still be found by homeowners renovating their homes.
What is the difference between BX and NM?
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.
How much does a BX cutter cost?
If you expect to be doing a lot of cutting, you may wish to invest in a special BX cutter, such as the Roto-Split. This tool costs between $20 and $50 and makes the job of splitting and ripping back BX cable far easier and safer than by hand.
Can BX cable be cut?
BX cable's metal sheathing can be hard to cut without nicking or severing the inner wire. NM cable, too, presents the danger of nicking inner wires. But because the outer sheathing is softer, less force is required to cut it.
Can you cut armor without a BX?
It is possible to cut and rip the armor without a BX cutting tool. You can cut the outer armor with a hacksaw, assisted with a strong pair of wire snippers or pliers. With this method, there is the danger of nicking the insulation on the inner wires, not to mention lacerating your fingers on the sharp metal armor.
Can BX armor be pierced?
BX's armor, while much stronger than NM's vinyl, can still be pierced by a determined and ill-placed nail or screw. However, with the exception of electrical wires that run through rigid metal conduits, no other type of electrical cable has as ...
