In summary, Bx cable is a type of wiring that consists of a flexible metal sheath and insulated conductors. It is used to distribute electricity within a building and provides protection against damage and fire hazards. Proper installation is essential to ensure the safety and efficiency of the electrical circuit.
A little BS on BX cables. Armored or Metal Clad Cables used in exterior installations.
It is commonly bx cable definition used in applications where the wiring needs to be protected from physical damage, such as in walls, ceilings, and floors. The metal armor of the Bx cable helps to prevent the wire from being damaged by nails, screws, or other objects that may come into contact with it. To ground BX electrical cable, the outer metal casing acts as the grounding conductor.
Pros and Cons of BX Wires
- Also often referred to as BX cable, it’s a time-tested solution for ensuring electrical safety and efficiency.
- However, upon opening a wall or ceiling, you may come across the ribbed metal-clad BX cable, which may be preferred in certain situations.
- A fabricated assembly of insulated conductors in a flexible interlocked metallic armor.
- The metal armor of the Bx cable helps to prevent the wire from being damaged by nails, screws, or other objects that may come into contact with it.
Although BX wiring has been extensively used, it remains a viable option for modern projects, offering unique benefits that make it a more suitable choice than NM cables. Yes, BX’s metal sheath offers superior puncture resistance, making it more durable than NM cable, which has a vinyl covering. Yes, BX cable is generally more expensive than NM cable, largely due to its metal sheathing and durability. BX cable can be used in some exposed installations, but you should check local codes to ensure it’s approved for outdoor use in your area. If you need help with BX cable installation or other electrical services, Right Touch Electrical can help. With years of experience and a commitment to safety and quality, we provide electrical services that meet all industry standards.
Electrical work can be dangerous, so taking the necessary precautions is crucial. The first solution to these problems is to keep cable lengths in buildings short since pick up and transmission are essentially proportional to the length of the cable. Beyond this, there are particular cable designs that minimize electromagnetic pickup and transmission.
- Armored cable is a type of electrical cable that is designed with an additional layer of protection to safeguard the conductors from external factors, such as moisture, impact, and abrasion.
- BX cables for wiring in residential and commercial environments are still very versatile today.
- Running electric cables from the electrical panel to devices like outlets or switches is crucial to any electrical project.
- BX cable design allows for easy bending and handling in corners and tight spaces, making it ideal for a wide range of installation applications.

Also often referred to as BX cable, it’s a time-tested solution for ensuring electrical safety and efficiency. We also offer other types of electrical solutions including electrical panel replacement, whole-house generator configuration, ceiling fan replacement, safety inspections, and lighting installation. This metal-clad cable is contrasted with newer non-metallic (NM) cables, such as the popular Romex brand, which has a slick vinyl covering, making it easier to rip and pull through holes in studs. BX wiring (also known as armored cable) is the 2nd generation of wiring used in homes. BX wiring was used until the late 1940s, when it was replaced by early Romex (non-metallic sheathed cable).
Armored cable is a type of electrical cable that is designed with an additional layer of protection to safeguard the conductors from external factors, such as moisture, impact, and abrasion. This added layer of protection is usually made of metal, such as steel, aluminum, or a combination of both. The use of armored cable can be traced back to the early 20th century, when it was first introduced to provide a durable and safe solution for electrical wiring in challenging environments.
Durability and Lifespan
The metal armor acts as a sturdy barrier, safeguarding the internal wires from physical harm. BX cable, also known as metallic sheathed cable, type AC, MC, Greenfield, or armored cable, consists of plastic-coated insulated wires (typically 14- or 12-gauge) protected by a metal sheath. This metal sheath features a ribbed appearance, made by wrapping a metallic strand in a helix around the wires. This construction makes BX cable distinct from non-metallic (NM) cable, which has a smooth vinyl covering. For a more detailed understanding of these cable types, check out this article on the difference between 14-2 and 14-3 wire types.
Its origins are linked to a time of fast urban growth and industrial development. First introduced around 1910, it became a popular choice for both residential and commercial buildings, especially as cities grew and electrical systems evolved. The term “BX” is often thought to be a reference to the Bronx, New York, where the cable gained early traction. Unlike NM cables, which rely on separate grounding wires, BX cable grounds through the metal casing itself. This means it can be a more straightforward option in certain situations, especially in buildings where metal boxes are used.
Three of the principal design techniques are shielding, coaxial geometry, and twisted-pair geometry. Given all that, go ahead and look at the differences between AC, MC, FMC, and FMT in your code book. I am constantly on the lookout for innovative solutions and products that can add value to your home and life. Periodically inspect fasteners and conduit for signs of wear or damage, and replace them as necessary. Older BX wiring does not have to be removed unless the wire coating inside the sheathing is in bad condition.
In the field of electrical installations, BX cable is a cornerstone for efficiently supplying power and signaling within buildings and structures. This flexible cable, durable and versatile has been a mainstay in the industry for decades, providing a solid solution for cabling needs in various sectors. Our goal is to delve deeper into the complexities of the BX cable, its uses, benefits and why it remains a preferred choice for electrical professionals. 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. Electrical cable jacket material is usually constructed of flexible plastic which will burn.
Advantages and Applications
Remember, proper installation of Bx cable is crucial for the safety and functionality of your electrical wiring. If you are unsure about any step, it is recommended to consult a licensed electrician. Use proper cutting tools and techniques, strip and terminate the cable, making sure connections are secure and reliable. It is important to note that electrical work should always be performed by qualified electricians who are familiar with local electrical codes and safety regulations.. You can cut the outer armor with a hacksaw, assisted with a strong pair of wire snippers or pliers.
Thus, there is no failure when one pursues a virtuous and noble mission as one’s life goal. A perspective shift to the meaning mindset helps eliminate one main source of human misery related to the striving to achieve material success or worldly fame. Cutting BX cable requires a bit more effort than working with NM cable, but with the right tools, it’s manageable.
Ensure this metal casing is securely connected to metal junction boxes, which will complete the grounding path. Proper grounding enhances safety by reducing the risk of electrical faults and ensures compliance with electrical codes. Better yet, use a special armored cable cutting tool.NM cable can be cut with a lineman’s pliers or even with the cutter on a wire stripper.CodeBX is accepted by the National Electrical Code (NEC). Such deep knowledge can only be achieved by an integrative and collaborative endeavor. BX cable is used to provide robust protection for electrical wiring in indoor environments. The armored exterior protects the internal conductors from physical damage and environmental factors, ensuring reliable and safe electrical transmission.
