Wacker Neuson 5000164752 AC Med GFI Wiring Harness US

The Wacker Neuson is a genuine OEM AC Med GFI Wiring Harness US designed for the GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A portable generator series. Sourced directly from Wacker Neuson, this harness is manufactured to the exact electrical specifications of the original component installed at the factory. It fits across a wide range of GP and GPS series configurations including standard, wheel kit, electric start, CARB GFI, and EPA-compliant variants. When your generator's GFI circuit or AC wiring shows signs of damage, corrosion, or failure, part number restores proper function without guesswork or adaptation.

Key Features

• Correct Wiring Gauge and Connector Spec — Genuine OEM construction ensures conductor sizing, insulation rating, and terminal connectors match the original harness exactly, maintaining proper current capacity for the GFI-protected AC output circuit.
• Drop-In Replacement for GP and GPS Series Generators — Engineered to route and terminate identically to the factory harness, allowing straightforward removal and reinstallation without splicing or rewiring.
• Broad GP Series Coverage — A single part number covers GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A units across standard, wheel kit, electric start, CARB GFI, and EPA configurations.
• Protects GFI Circuit Integrity — A correctly functioning AC wiring harness ensures the GFI outlet circuit operates as designed, tripping appropriately under fault conditions and delivering stable power output to connected equipment.
• Electrical Safety Compliance — The GFI wiring harness is a safety-critical component; using a genuine OEM part maintains the ground-fault protection function that shields operators and connected tools from electrical hazard.

The AC wiring harness carries power from the generator's alternator output to the GFI-protected receptacle panel, providing the electrical pathway through which 120V AC current reaches connected tools and equipment. The GFI (Ground Fault Interrupter) portion of the circuit monitors current flow and cuts power within milliseconds if a ground fault is detected, protecting operators from electric shock. When the harness develops damaged insulation, broken terminals, or corroded conductors, the generator may fail to deliver power, trip repeatedly without a true fault, or — more critically — lose GFI protection entirely.
