A New Power Distribution Box and Disconnect Switch Is Used on C175-16 Generator Set Engines {1417, 1420, 4461}
- Generator Set:
- C175-16 (S/N: WYB1-UP)
Description of Change: The new power distribution box distributes both low current and high current. The new box provides the following benefits:
- Improved protection from moisture and other environmental factors
- One circuit breaker panel for both the high current and low current
- Connectors for the circuit breakers rather than individual wires
- The circuit breakers use connectors that are more robust than the previously used ring terminals on small studs
- The wiring in the panel is more secure
- The ground wire from the disconnect switch to the starting motor is more secure
- The previously used low current distribution box has been consolidated into the new power distribution box.
