Southwire 590 Emt to Bx Combination Coupling 1/2 in

Product Description

The SOUTHWIRE 590 is a 1/2 inch stainless steel combination coupling designed to connect EMT conduit to BX armored cable in a single fitting. This type of transition coupling eliminates the need for two separate connectors when joining EMT and AC or BX cable systems. It is used in electrical raceway installations where conduit and armored cable meet at a junction box or panel. Licensed electricians and electrical contractors install this fitting as part of branch circuit wiring in commercial and residential applications. The stainless steel construction provides corrosion resistance in demanding environments.

The SOUTHWIRE 590 combination coupling suits installations where EMT conduit transitions to BX or AC armored cable. It is rated for 1/2 inch trade size on both the EMT and BX sides. Typical use cases include panel feeder connections, junction box entries, and conduit runs that terminate into flexible armored cable sections. This fitting is suited for indoor and protected outdoor electrical installations handled by a licensed electrician.

Key Features

• Combines EMT conduit and BX armored cable connection in one fitting
• 1/2 inch trade size fits standard conduit and armored cable
• Stainless steel construction for corrosion resistance
• Reduces hardware count by eliminating two separate connectors
• Designed for use at junction boxes and enclosure knockouts

Compatibility

Designed as an OEM-style replacement fitting for 1/2 inch EMT to BX armored cable transition applications in standard electrical enclosures and junction boxes.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 358 for EMT and NEC Article 320 for armored cable. De-energize the circuit and verify with a voltage tester before beginning work. Secure the EMT conduit end and the BX cable end fully into the coupling before tightening. Do not overtighten the cable clamp, as this can damage the armor and internal conductors.
