Yes, AC cable is still manufactured and used, although MC cable has become more prevalent in many applications. Here's a breakdown of the key differences and usage: AC Cable (Armored Cable)

Construction: AC cable consists of insulated conductors individually wrapped in paper and then encased in a flexible metal armor. Grounding: It relies on the metal armor as the equipment grounding conductor (with an aluminum bonding strip in modern versions). Uses: Historically used in residential and commercial construction, particularly for branch circuits and connections to light fixtures. Still permitted by the NEC but has seen a decline in usage because of MC cable.

MC Cable (Metal-Clad Cable)

Construction: MC cable contains insulated conductors bundled together, with a separate equipment grounding conductor (typically a green or bare wire), and then encased in a metal sheath. Grounding: It uses the internal equipment grounding conductor. Uses: Can be used in many of the same applications as AC cable, but is generally considered more versatile. Its distinct grounding conductor can simplify installations and meet more stringent grounding requirements in some situations.

Reasons for the Shift to MC Cable



Improved Grounding

The separate grounding conductor in MC cable is often preferred for its more reliable and dedicated grounding path.

Versatility

MC cable can be used in a wider range of applications, including those requiring specific grounding configurations or higher voltage levels.

Ease of Installation

MC cable often has features that make it easier to strip and terminate.

Code Requirements

Modern electrical codes in some jurisdictions may favor or require MC cable in certain installations due to its grounding benefits.

In summary:

While AC cable is still manufactured and allowed by the NEC, MC cable is generally more versatile and often preferred due to its separate grounding conductor. The specific choice depends on the application, local codes, and project specifications. Flag for review
