Its flexibility, integrated grounding conductor, and superior fire resistance make it ideal for environments requiring high safety standards and ease of installation. The increasing emphasis on arc fault protection and compliance with NEC (National Electrical Code) requirements, particularly Article 330, is driving contractors toward MC cable for its code-compliant design.

2. Decline in BX Cable Usage Due to Regulatory and Safety Concerns
   BX cable, while historically popular for residential use, is seeing reduced adoption due to limitations in grounding reliability and its inability to meet the latest NEC standards without modification. By 2026, stricter enforcement of electrical safety codes—especially in new construction and retrofit projects—will likely accelerate the phase-out of BX in favor of more modern alternatives. The absence of a dedicated equipment grounding conductor (EGC) in older BX designs is a key disadvantage in markets prioritizing safety and liability reduction.

3. Labor Efficiency and Installation Speed Favoring MC Cable
   With rising labor costs and a growing skilled labor shortage, contractors are prioritizing installation efficiency. MC cable, which often includes pre-assembled components and easier termination methods, reduces labor time compared to BX, which may require additional grounding measures. This efficiency advantage positions MC as the preferred choice in time-sensitive projects, further widening its market lead by 2026.

4. Sustainability and Material Innovation
   Manufacturers are investing in lightweight, aluminum-jacketed MC cables that reduce material costs and environmental impact. These innovations align with green building trends and support LEED certification goals, giving MC an edge in sustainable construction markets. In contrast, BX cable technology has seen minimal innovation, limiting its appeal in eco-conscious projects.

5. Regional Market Variations
   While MC cable adoption is strong nationwide, especially in urban and code-strict regions (e.g., California, Northeast U.S.), some rural or residential retrofit markets may still use BX due to lower material costs and familiarity among local electricians. However, even in these areas, the long-term trend points toward MC as training and awareness improve.

6. Impact of Smart Buildings and Power Over Ethernet (PoE)
   The rise of smart buildings and increased demand for PoE systems require reliable, shielded, and code-compliant wiring solutions. MC cable’s superior EMI shielding and compatibility with low-voltage systems make it better suited for these applications than BX, further boosting its relevance in the evolving infrastructure landscape.

Conclusion:
By 2026, MC cable is expected to hold a dominant position in the market, driven by safety regulations, labor efficiency, and technological adaptability. BX cable will likely remain in niche or legacy applications but will continue to lose ground overall. Electrical contractors, specifiers, and developers are increasingly favoring MC for its compliance, performance, and future-readiness, marking a clear trend toward modernization in electrical infrastructure.

Common Pitfalls Sourcing MC vs BX Cable (Quality, IP)

When sourcing electrical cables like MC (Metal-Clad) and BX (a common term historically used for armored cables, often referring to AC or Type AC cable), understanding the differences and potential pitfalls is critical for ensuring safety, compliance, and long-term performance. Below are key pitfalls related to quality and IP (Ingress Protection) considerations when choosing between MC and BX/AC cable.

Misunderstanding Cable Types and Standards

A major pitfall is confusing MC cable with BX or AC cable due to outdated terminology. BX is a legacy term originally used for early forms of armored cable, but today’s electrical codes typically refer to AC (Armored Cable) rather than BX. MC cable is a more modern, code-compliant product with broader applications. Sourcing the wrong type due to terminology confusion can lead to code violations and safety hazards.

Overlooking Armor Construction and Grounding

MC cable features a continuous interlocking metal armor that acts as the equipment grounding conductor, provided it meets NEC (National Electrical Code) requirements. In contrast, older AC/BX cable relies on an internal bonding strip for grounding. Sourcing AC/BX without verifying the presence and integrity of the bonding strip can result in inadequate grounding, posing serious safety risks. Inferior quality AC cables may lack or damage this strip during installation.

Ignoring Environmental and IP Ratings

MC cables are often available with additional jackets (e.g., PVC) that provide moisture and chemical resistance, offering higher effective IP ratings (e.g., protection against dust and water ingress). Standard AC/BX cable typically lacks such a jacket, making it unsuitable for damp, wet, or outdoor locations. Sourcing AC/BX for environments requiring moisture protection leads to premature failure and non-compliance with IP standards.

Compromising on Quality and Material Thickness

Low-cost MC or AC cables may use thinner aluminum or steel armor, reducing mechanical protection and durability. Inferior interlocking armor can kink or separate during installation, exposing conductors. Additionally, substandard materials may corrode faster, especially in harsh environments. Buyers focusing solely on cost may end up with cables that fail under stress or do not meet code requirements.

Assuming Interchangeability in Applications

MC cable is approved for a wider range of applications than AC/BX, including outdoor use, direct burial (with proper jacketing), and in commercial/industrial settings. AC cable is generally limited to dry indoor locations. Sourcing AC/BX for applications requiring MC cable results in non-compliant installations and potential insurance or inspection issues.

Neglecting Third-Party Certification and Documentation

A common quality pitfall is sourcing cables without proper certification (e.g., UL, ETL). Counterfeit or uncertified MC/AC cables may not have undergone rigorous testing for fire resistance, armor strength, or electrical safety. Always verify certification marks and request test reports to ensure compliance with NEC and IP-related performance standards.

Inadequate Attention to Jacket Integrity for IP Protection

For environments requiring dust or moisture resistance (e.g., IP54 or higher), the outer jacket of MC cable plays a crucial role. Sourcing MC cable without a robust outer jacket—or selecting AC cable, which lacks one—results in insufficient ingress protection. Always confirm the cable’s jacket material and thickness when IP ratings are a concern.

Conclusion

To avoid these pitfalls, clearly define project requirements, use correct terminology (MC vs. AC, not BX), source from reputable suppliers, and verify certifications. Prioritize cables with appropriate armor, grounding provisions, and jacketing to meet both quality and IP protection needs.

Logistics & Compliance Guide for MC vs. BX Cable

Understanding the differences between Metal-Clad (MC) and BX (Armored Cable) cables is essential for proper logistics planning and regulatory compliance in construction and electrical installations. This guide outlines key considerations for handling, transporting, storing, and installing both cable types in accordance with industry standards.

Definition and Key Differences

MC Cable (Metal-Clad Cable)
MC cable is a factory-assembled assembly consisting of one or more insulated conductors enclosed in a flexible, interlocking metal sheath. It typically includes an internal bonding strip or equipment grounding conductor. MC cable is designed for both indoor and outdoor use and meets modern National Electrical Code (NEC) requirements.

BX Cable (Armored Cable)
BX cable is an older type of armored cable that also features insulated conductors wrapped in a flexible metal armor. However, it lacks a dedicated internal bonding strip or grounding conductor. BX cable relies on the armor itself for grounding, which can be less reliable and is often not compliant with current NEC standards in many applications.
