The Honda 38240-Z22-E31 is a genuine OEM Circuit Protector (20A) designed for Honda EB, EG, and EM series generators, including the EB10000, EB3800, EB5000, EB6500, EG4000, EG5000, EG6500, EM3800, EM5000, and EM6500. As a direct Honda OEM component, this circuit protector is manufactured to the same specification as the unit installed at the factory, ensuring it functions exactly as intended within the generator's output panel. Verify your generator's serial number against the fitment table before ordering, as Honda updates part numbers at production breaks and the correct protector rating matters for safe circuit operation.
Key Features
- Genuine OEM Circuit Protection — sourced directly from Honda, this 20A protector delivers the precise trip threshold the generator's output circuit was engineered around, not an approximated aftermarket equivalent.
- Exact-Replacement Fit — built to drop into the existing panel position on compatible Honda generators without alteration, restoring the output circuit to its original protected state.
- Broad Generator Compatibility — covers ten Honda conventional generator models across the EB, EG, and EM lines, including the EB10000, EB5000, EG5000, EM5000, and more.
- Serial Number Verification Recommended — Honda revises components at specific production points, so confirm your unit's serial number against the fitment table to ensure this is the correct protector for your machine.
- Restores Full Output Capacity — a tripped or failed circuit protector cuts power to the load circuit entirely; replacing it with the correct 20A OEM unit brings that circuit back online at its rated capacity.
A circuit protector is a resettable overcurrent device mounted in the generator's output panel. It monitors the current drawn on a particular outlet circuit and trips — interrupting the circuit — if that current exceeds its rated limit, in this case 20 amps. This protects both the connected equipment and the generator's internal wiring from damage caused by overload or a short circuit. When the protector trips repeatedly or fails to reset and hold, it must be replaced with a unit of the correct rating; substituting a protector with a different amperage changes the protection threshold the generator was designed around and can leave the circuit unprotected or unnecessarily restrictive.
