West Penn Wire 25240BGY1000 22AWG 4-cond Plenum Cable 1000ft

Product Description

The WEST PENN WIRE 25240BGY1000 is a 22 AWG 4-conductor solid unshielded plenum-rated cable supplied in a 1000-foot put-up. Built for installation in air-handling plenum spaces, this cable meets the stricter smoke and flame requirements that standard CMR or CL2 cables cannot satisfy. The solid conductor construction keeps resistance consistent over long runs, making it well-suited for low-voltage control and signaling circuits where signal integrity matters. Electricians and low-voltage technicians working in commercial and institutional environments specify plenum-rated cable whenever conduit or cable trays run through air-return ceiling spaces or HVAC plenums per NEC Article 800 and related code sections.

This cable is commonly used for fire alarm initiating circuits, access control wiring, security system runs, and general low-voltage building automation control wiring. The gray jacket color aids in visual identification during rough-in and future service work. The 1000-foot continuous spool length reduces splice points on long commercial floor runs and is a standard stocking size for electrical contractors and systems integrators handling multi-zone installations.

Key Features

• 22 AWG solid conductors for stable resistance on extended low-voltage runs
• 4-conductor configuration supports multi-wire control and signaling circuits
• Plenum-rated jacket meets NEC requirements for installation in air-handling spaces
• Unshielded construction simplifies termination in environments without significant EMI concerns
• Gray jacket color for easy visual identification during installation and service
• 1000-foot spool minimizes field splices on large commercial jobs

Compatibility

Designed for use in plenum-rated low-voltage wiring applications including fire alarm, access control, security, and building automation systems where NEC plenum cable requirements apply.

Installation Notes

Installation must be performed by a licensed electrician or qualified low-voltage technician in accordance with the National Electrical Code and applicable local codes. Verify the plenum rating is required for the specific pathway before substituting this cable in non-plenum runs. De-energize all circuits at the panel before making terminations. Avoid sharp bends that exceed the cable minimum bend radius, and do not staple through the jacket in a way that deforms the conductors.
