Genie 684640GT Receptacle, 20A 120V Duplex GFI

The Genie 684640GT is a genuine OEM Receptacle, 20A 120V Duplex GFI designed for Genie and Terex portable light towers including the AL4000, AL5000, AL4, AL5, AL5HT, AL4L, AL5L, RL4, and AL5 with Vertical Mast models. As a factory-direct OEM part, this receptacle is built to match the original electrical specifications of the unit it replaces, ensuring correct voltage and amperage ratings right out of the box. Cross-reference part number 684640GT against your machine's parts manual to confirm it is the correct fit for your specific light tower configuration.

Key Features

• Correct Electrical Rating — Rated at 20A and 120V to match the original output specification, so the replacement performs exactly as the factory-installed unit.
• Duplex GFI Protection — Ground fault interrupter design provides built-in circuit protection, automatically cutting power if a fault is detected to protect connected equipment and operators.
• Genuine OEM Part — Sourced directly from Genie, this receptacle meets the same dimensional and electrical standards as the component it replaces — no adaptation needed.
• Wide Light Tower Fitment — Compatible with multiple AL and RL series Genie and Terex light towers, including the AL4000, AL5000, AL5HT, and RL4 models.
• Restored Jobsite Power Access — A failed or damaged receptacle leaves workers without a safe power outlet on site; replacing it with this OEM unit restores full power access from the light tower's generator output.

The duplex GFI receptacle on a portable light tower provides grounded, ground fault-protected 120V AC power outlets for connecting tools and equipment in the field. The ground fault interrupter function continuously monitors the circuit and trips the outlet instantly if it detects current leaking outside the intended path — a critical safety feature in outdoor and wet jobsite environments. When the receptacle cracks, its contacts wear, or the GFI mechanism fails to reset, the outlet becomes either unusable or unsafe and should be replaced promptly with the correct OEM component.
