Ensure top-tier electrical safety and contractor-level performance with the GF20B by Cooper Wiring Devices (Eaton). This specification-grade GFCI duplex combines advanced self-test capabilities with a slim, space-saving design, delivering continuous protection in residential, commercial, and light-industrial environments.

Key Features

• Automatic Self-Test – Periodically verifies ground-fault protection and disables the outlet if functionality is compromised, signaling via LED.
• Slim Profile Design – Only 1.03" deep, ideal for shallow electrical boxes and flush installations.
• Self-Test GFCI Protection – Trip response within 0.025 seconds to prevent electric shock (Class A).
• SafeLock Miswire Protection – Blocks resets if miswired or if GFCI circuit fails.
• Tamper-Resistant (TR) – Internal shutter system enhances child safety and meets NEC regulations.
• LED Status Indicators – Visual indication of power, trip conditions, and end-of-life status.
• Back-and-Side Wiring – Supports #14–#10 AWG copper conductors with secure clamps.
• Automatic Grounding – No separate grounding jumper required in grounded metal boxes.
• Durable Materials – Polycarbonate/thermoplastic housing, brass contacts, and steel strap built for 10 kA short-circuit endurance.
