The Wacker Neuson GFCI Module is a genuine OEM component designed for the GP and GPS series portable generators, including the GP3800A, GP5600A, GP6600A, GPS5600A, and GPS6600A. As a direct OEM replacement, this module is sourced and specified by Wacker Neuson to meet the exact electrical tolerances required for proper ground fault circuit interrupter protection on these units. It fits across a wide range of EPA and CSA configurations within the GP and GPS generator families, making it the correct choice whether your machine is configured for the US or Canadian market. If your generator's GFCI outlet has tripped and will not reset, or the module has failed entirely, part number is the verified replacement to restore full outlet functionality.
Key Features
- Correct Trip Threshold and Output Spec — Genuine OEM GFCI Module engineered to the precise fault-detection sensitivity required for these generator models, ensuring proper circuit interruption without nuisance trips.
- Drop-In Electrical Replacement — Plugs directly into the existing outlet panel wiring harness on GP and GPS series generators with no re-wiring or adapter required.
- Broad GP and GPS Family Coverage — Verified fitment across GP3800A, GP5600A, GP6600A, GPS5600A, and GPS6600A generators in both EPA and CSA configurations.
- Restored Protected Outlet Operation — A functioning GFCI Module keeps the generator's protected outlets operational, allowing tools and equipment to draw power safely on site.
- Electrical Safety Compliance — Replacing a failed or degraded GFCI module with an OEM-spec unit maintains the ground fault protection your generator was built to provide, which is critical when powering tools in wet or outdoor environments.
A GFCI (Ground Fault Circuit Interrupter) Module monitors the flow of current through the generator's protected outlets and trips the circuit the instant it detects a ground fault — protecting operators from electric shock in damp or outdoor conditions. On Wacker Neuson GP and GPS series generators, this module is integrated into the outlet panel and handles both the sensing and interruption functions. When the module fails, the protected outlets either lose power entirely, trip immediately on reset, or stop providing reliable fault protection — any of which puts both equipment and operators at risk. Replacing part 5200003741 restores the generator's GFCI functionality to its original operating standard.
