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.
BX Wiring
BX cable, or armored cable, is an indoor wiring type with insulated wires protected by a flexible, galvanized steel cover, providing enhanced safety and durability. BX cable’s metal armor offers excellent protection against physical threats like nails or screws, making it more durable than NM cables. While old BX wiring can support modern power demands if in good condition, the inner insulation might degrade at exposed ends over time. The main purpose of Bx cable is to protect the electrical wires inside from damage and to provide a pathway for the electricity to flow. The cable consists of a flexible metal sheath, usually made of steel or aluminum, which acts as a protective barrier around the insulated conductors. Bx cable, also known as armored cable or AC cable, is a type of wiring used in electrical circuits.
Advantages and Applications
BX cable is an indoor armored wiring system with insulated wires protected by a galvanized steel strip, offering robust protection similar to rigid conduit. BX cable remains a valuable option for electrical installations, particularly in areas where protection from physical damage and grounding through armor are important. While it may be heavier and more expensive than NM cable, its durability and ability to be used in exposed locations make it a solid choice for certain projects. In conclusion, Bx cable is a versatile and reliable option for electrical wiring. Its armored design provides extra protection and insulation, making it suitable for a variety of applications.
It is commonly 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.
Safety and Installation Tips
- In summary, Bx cable is a type of wiring that consists of a flexible metal sheath and insulated conductors.
- 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).
- Bx cable is commonly used in residential and commercial buildings for a variety of applications, including lighting, outlets, switches, and appliances.
- The term “BX” is often thought to be a reference to the Bronx, New York, where the cable gained early traction.
- We hope that this guide has given you the relevant specialized details about BX cables and how they are cut and installed.
In conclusion, Bx cable offers several advantages over other types of wiring, including durability, protection, flexibility, fire resistance, and ease of installation. It is commonly used in residential, commercial, outdoor, renovation, and industrial applications due to its reliability and versatility. The insulated conductors inside the cable are usually color-coded to indicate their function, such as black for hot wires, white for neutral wires, and green or bare copper for ground wires. Installing Bx cable is a relatively straightforward process, but it does require some knowledge of electrical wiring and circuits.

- This armored construction makes them both easier to install than traditional conduit wire, which helps reduce installation costs.
- This typically involves running the cable through holes or conduits in the walls, ceilings, or floors.
- The BX cable, also known as shielded cable, is a type of electrical cable composed of wires enclosed within a flexible metal conduit.
- This causes the voltages induced by a magnetic field between the shield and the core conductor to consist of two nearly equal magnitudes which cancel each other.
- It is important to ensure that the cable is cut straight and that the ends are properly stripped to expose the conductors.
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.
Installation Considerations
It is commonly used in residential, commercial, and industrial electrical installations. BX cable is a type of indoor wiring consisting of two or more insulated wires protected by a wound, galvanized steel strip cover. Bx cable is commonly used in residential and commercial buildings for a variety of applications, including lighting, outlets, switches, and appliances. It is suitable for both indoor and outdoor installations, as it provides excellent protection against moisture, physical damage, and fire hazards. It’s often preferred over non-metallic sheathed cables in environments where extra protection is necessary due to potential physical damage. When planning an electrical installation, one of the first things you’ll encounter is the type of cable to use.
What is BX Cable? What is AC Cable?
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 bx cable definition 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.
During the installation process, the Bx cable is typically run through walls, ceilings, and floors, and secured using appropriate fasteners. It is important to follow electrical codes and guidelines when installing Bx cable to ensure safe and reliable operation. In the next section we will learn about the complete use of bx cables, including cutting methods and grounding.
Finally, fasten the grounding wire to the electrical panel’s grounding bus bar. Despite these differences, BX wires and MC cables share similarities in their basic armored structure, providing better protection for individual conductors compared to non-metallic (NM) cables. Both types of cable are simpler to install than wire in conduits, potentially reducing costs. BX wiring, with its metal sheath, is far more durable and less prone to damage over time. It’s a reliable choice for electrical projects that require both physical protection and grounding. Following these step-by-step instructions will help you install BX cable for your electrical circuits safely and efficiently.
