Southwire bx143 14 Awg 3 Conductor Armored Cable

Product Description

The SOUTHWIRE bx143 is a 14 AWG, 3-conductor armored electrical cable, commonly known as BX or AC cable, designed for branch-circuit wiring in residential and light commercial applications. The interlocked steel armor jacket provides mechanical protection for the conductors, making it suitable for exposed or concealed installations where standard NM cable is not permitted. Electricians select this cable for circuit runs in drywall, concrete block, and other construction environments that call for a listed armored assembly. This product is sold by the foot with a minimum order quantity of 250 feet.

This armored cable is used in a wide range of branch-circuit wiring scenarios, including general-purpose 15-amp circuits for lighting, receptacles, and small appliances. It is commonly installed in residential new construction, renovation projects, and light commercial work where local codes require armored cable in place of nonmetallic sheathed cable. The 3-conductor configuration supports standard line, neutral, and ground wiring in single-phase 120-volt circuits.

• 250-foot minimum order quantity per purchase

Compatibility

Designed as an OEM-style replacement and general-use armored cable for residential and light commercial branch-circuit wiring applications requiring 14 AWG 3-conductor armored cable assemblies.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit and verify zero voltage with a meter before making any connections. Use a listed anti-short bushing at each cable termination where the armor is cut, and secure the cable with listed clamps or connectors at all boxes and enclosures. Do not bend the cable tighter than the minimum bend radius specified for armored cable.
