The Genie 684640GT Duplex GFI Receptacle, 20A 120V is a genuine OEM electrical component designed for Genie and Terex portable light towers, including AL4000, AL5000, RL4000, TML-4000, and AL5HT models, along with additional AL and RL series units. As a direct OEM replacement, this receptacle matches the original specification — correct voltage rating, outlet configuration, and ground-fault interrupt protection — so there is no guesswork about compatibility. Cross-reference part number 684640GT against your machine's parts manual to confirm it is the right component for your unit before ordering.
Key Features
- Correct Electrical Rating — Rated at 20A, 120V to match the original outlet specification on Genie and Terex light towers, ensuring proper load handling for connected equipment.
- Genuine OEM Construction — Manufactured to Genie OEM standards with appropriate contact materials and housing grade for outdoor jobsite use on portable light towers.
- Duplex GFI Configuration — Dual-outlet ground-fault interrupt design matches the original receptacle layout, allowing the same tools and accessories to plug in without adapters.
- Broad Light Tower Fitment — Fits multiple Genie AL and RL series light towers, including AL4, AL4L, AL4000, AL5, AL5L, AL5HT, AL5000, RL4, RL4 Vertical Mast, RL4000, AL4 Vertical Mast, AL5 with Vertical Mast, and TML-4000.
- Ground-Fault Protection Preserved — A functioning GFI receptacle cuts power instantly on detecting a ground fault, protecting operators using power tools and equipment plugged into the light tower's outlets.
- Electrical Safety on the Jobsite — Replacing a failed or damaged GFI receptacle with the correct OEM part restores the circuit protection the machine was built with, keeping users safe when drawing power from the tower.
A duplex GFI receptacle provides two 120V outlet positions with built-in ground-fault circuit interrupt protection. On a portable light tower, this receptacle serves as the onboard power access point, allowing operators to run tools or accessories directly from the generator. When the GFI detects a leakage current — often caused by a damaged cord or tool — it trips and cuts the circuit within milliseconds to prevent electric shock. A cracked housing, burned contacts, or a tripped GFI that will not reset are all signs the receptacle needs to be replaced. Fitting the correct OEM component, such as this one identified by part number 684640GT, restores the outlet to its original rated capacity and keeps ground-fault protection functioning as intended.
