Appleton C-550 Bx Cable Connector 3/8 Inch Die Cast

Product Description

The APPLETON C-550 is a 3/8 inch die-cast set screw connector designed for use with BX armored cable. It provides a secure, code-compliant termination point where armored cable enters an electrical enclosure, junction box, or panel knockout. The set screw design locks the connector firmly onto the cable jacket without requiring specialized tooling, making installation fast and repeatable. Electricians use this connector in both new construction and retrofit wiring work where armored cable is the specified wiring method.

This connector is suited for residential and light commercial electrical installations where BX or AC-type armored cable is routed to junction boxes, outlet boxes, or load centers. It fits 3/8 inch knockouts and is appropriate for indoor dry or damp-location applications typical of armored cable installations. Licensed electricians performing branch circuit wiring will encounter this fitting as a standard component in armored cable assemblies.

Key Features

• 3/8 inch trade size fits standard 3/8 inch knockouts on electrical enclosures and boxes
• Die-cast construction provides solid, durable clamping to armored cable jackets
• Set screw securing method allows tool-simple installation without ratchet-style clamps
• Compact body profile suits tight box and enclosure installations

Compatibility

Designed as an OEM-style fitting for use with 3/8 inch trade size BX or AC armored cable terminations at standard electrical enclosure knockouts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for armored cable wiring methods. De-energize the circuit and verify absence of voltage before securing the connector or making any wire terminations inside the enclosure. A flathead or hex key driver is typically used to tighten the set screw against the cable jacket. Do not overtighten the set screw to the point of deforming the cable jacket or conductors beneath.
