Abb WJT-5018 Conductor Marker 277 Volts

Product Description

The ABB WJT-5018 is a conductor marker rated for 277-volt applications, designed to identify and label electrical conductors in commercial and industrial wiring systems. Conductor markers provide clear, durable identification on wires and cables, reducing misidentification during installation, maintenance, and inspection. This marker is suited for use by licensed electricians working on branch circuits, panel feeders, and lighting circuits commonly found in commercial facilities. The 277-volt rating makes it appropriate for single-phase lighting loads fed directly from 480-volt three-phase distribution systems.

This conductor marker is commonly used in commercial electrical installations where 277-volt lighting circuits are prevalent, including office buildings, warehouses, retail spaces, and industrial facilities. Electricians use markers like the WJT-5018 to maintain NEC-compliant conductor identification, especially in multi-wire branch circuits and panels where clear labeling is critical for safe ongoing service and inspections.

Key Features

• Rated for 277-volt conductor identification applications
• Suitable for marking branch circuit and feeder conductors in commercial systems
• Compact form factor fits standard electrical panel and conduit labeling workflows
• Supports NEC conductor identification requirements for voltage-level marking

Compatibility

Designed as an OEM-style conductor marker for use in 277-volt electrical systems, compatible with standard conductor labeling applications in commercial and industrial wiring installations.

Installation Notes

Installation and application should be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before applying conductor markers to live panels or junction boxes. Verify voltage rating of the marker matches the circuit voltage before use. Follow all applicable local electrical codes during installation.
