The Honda 38220-Z16-D21 Circuit Breaker (15A) is a genuine OEM component designed for Honda EM3800, EM5000, and EM6500 generators. As a direct Honda OEM part, it is built to the same specification as the breaker that left the factory, ensuring the output panel on your generator operates exactly as intended. Honda supersedes parts at serial breaks, so confirm your generator's serial number against the fitment table before ordering to make sure part number 38220-Z16-D21 is the correct breaker for your unit.
Key Features
- Genuine OEM Protection Rating — a true Honda OEM breaker rated at 15A, matched to the electrical load specifications Honda engineered into the EM3800, EM5000, and EM6500 output circuits
- Direct-Fit Replacement — replaces the original breaker without modification, dropping into the existing panel position for a straightforward swap
- Generator Fitment — confirmed for Honda EM3800, EM5000, and EM6500 generators; verify your serial number against the fitment table to confirm applicability to your unit
- Restore Overload Protection — a worn or tripped-and-failed breaker leaves output circuits without overcurrent protection; replacing it with this part restores the generator's ability to trip safely under fault conditions
A circuit breaker is the overcurrent protection device mounted in a generator's output panel. When the electrical load on a circuit exceeds the breaker's rated amperage — in this case 15A — the breaker trips and interrupts the circuit, protecting both the generator's windings and connected equipment from damage caused by excess current. Unlike a fuse, a circuit breaker can be reset after a trip; however, a breaker that has tripped repeatedly or fails to hold its rated load must be replaced, because a breaker that no longer trips reliably offers no meaningful protection to the generator or to whatever is plugged into it.
