Mc-a 250-250-250-250 Stranded Aluminum Armor Cable

Product Description

The mca250-250-250-250strmr is a Type MC-A metal-clad cable featuring stranded aluminum conductors in an aluminum armor jacket. This cable is sold cut to length, making it suitable for large commercial and industrial electrical installations where custom runs are required. The 250 kcmil conductor size makes it appropriate for high-ampacity branch circuits, feeder runs, and service entrance applications. Licensed electricians working on commercial, industrial, or large residential projects typically specify this cable where flexible armor protection and aluminum conductors are required by the design or local code.

This MC-A cable is used in applications where metallic armor protection is required alongside large-gauge aluminum conductors. Typical installation scenarios include commercial buildings, industrial facilities, and multi-family residential projects. The cut-to-length format reduces waste and allows the installer to pull exact footage needed for each circuit run, minimizing excess material on the job site.

Key Features

• Stranded aluminum conductors rated at 250 kcmil per conductor
• Four-conductor configuration: 250-250-250-250
• Aluminum interlocked armor jacket for mechanical protection
• Cut-to-length format for custom installation runs
• Type MC-A construction for compliance with NEC Article 330 applications

Compatibility

Designed as a Type MC-A metal-clad cable for use in commercial and industrial wiring systems where NEC Article 330 permits metal-clad cable with aluminum conductors and aluminum armor.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 330 and applicable local codes. De-energize all circuits and verify zero voltage at the work area before beginning any termination or splicing work. Use appropriately rated aluminum-listed connectors and termination fittings compatible with MC-A cable armor. Bending radius minimums must be observed during installation to avoid conductor or armor damage.
