The Honda 38220-Z22-G20 Circuit Breaker (21A) is a genuine OEM component designed for Honda EB4000, EB5000, and EB6500 generators. As a direct OEM replacement, this circuit breaker is produced to Honda's exact specifications, ensuring it integrates properly with the generator's electrical protection system. Confirm your generator's serial number against the fitment table before ordering, as Honda periodically supersedes parts at production breaks within a model run.
Key Features
- Genuine OEM Overcurrent Protection — sourced directly from Honda, this 21A circuit breaker matches the original trip rating and terminal configuration, so the generator's load circuits are protected exactly as engineered.
- Direct OEM Replacement — replaces the original unit in Honda EB4000, EB5000, and EB6500 generators with no rework to the panel or wiring.
- Correct Trip Rating — the 21A rating is specific to this application; installing a breaker with the wrong rating would leave the generator's output circuits either under- or over-protected, so using the OEM part number 38220-Z22-G20 is the reliable way to maintain the correct threshold.
- Serial Number Verification Recommended — Honda revises parts within a model line at serial number breaks; check your unit's serial number against the compatibility table to confirm this is the right breaker for your specific generator.
A circuit breaker is the generator's built-in overload safeguard. When current drawn by connected equipment exceeds the breaker's rated threshold — in this case 21A — the breaker trips and interrupts the circuit, protecting both the generator's windings and the equipment plugged into it. Unlike a fuse, a circuit breaker can be reset once the overload condition is cleared, making it a reusable protective device. When a circuit breaker fails to trip under overload, or trips repeatedly under normal loads, replacing it with the correct OEM unit restores proper protection and normal operation to the generator's output panel.
