Wacker Neuson 5000163871 GFCI Aux Switch Wire

The Wacker Neuson is a genuine OEM GFCI Aux Switch Wire designed for the GP3800A, GP5600A, GPS5600A, GP6600A, and GPS6600A series portable generators. As a factory-original component, this wire is manufactured to the exact specification used in Wacker Neuson's production line, ensuring correct electrical continuity and secure connection within the GFCI protection circuit. It fits a wide range of GP and GPS series generator configurations, including standard, wheel kit, electric start, CARB, EPA, CSA, and CAN GFI variants. Verify your machine's model number before ordering to confirm compatibility with your specific unit.

Key Features

• Factory-Correct Conductor Spec — Manufactured to the exact gauge, insulation grade, and terminal configuration used in Wacker Neuson GP and GPS series generators, ensuring proper signal integrity through the GFCI circuit.
• Genuine OEM Component — Sourced directly from Wacker Neuson; part number 5000163871 matches the original part installed at the factory, so installation is straightforward with no guesswork on fitment.
• Broad GP/GPS Series Coverage — Compatible with GP3800A, GP5600A, GPS5600A, GP6600A, and GPS6600A generators across EPA, CARB, CSA, and CAN GFI regulatory configurations.
• Restores GFCI Protection Function — A damaged or broken aux switch wire can disable the generator's ground-fault circuit interrupter, leaving connected tools and equipment without overcurrent protection. Replacing it restores full GFCI functionality.
• Electrical Safety Critical — The GFCI system is a core operator and equipment safety feature. Using a correctly specified OEM wire ensures the circuit trips at the right threshold and meets the electrical requirements of the original safety design.

The GFCI Aux Switch Wire connects the auxiliary switch to the generator's ground-fault circuit interrupter system, allowing the GFCI to monitor current flow and cut power when a fault is detected. This wire carries the control signal that triggers the GFCI trip mechanism, making it essential to the safe operation of any tools or equipment plugged into the generator's GFCI-protected outlets. If the wire becomes broken, corroded, or disconnected, the GFCI circuit will not function correctly, potentially leaving operators exposed to ground-fault hazards — making prompt replacement with the correct OEM part a priority.
