Which panel of the A/M 32A-86 generator set has the circuit breaker for overload protection?

The correct choice highlights that the circuit breaker for overload protection of the A/M 32A-86 generator set is located on the external AC panel. This panel is designed to control the distribution of AC power generated by the unit to various loads. The inclusion of an overload protection circuit breaker is crucial for safeguarding electrical systems from excessive current, which can lead to overheating and potential damage. By being positioned on the external AC panel, it allows for easy access and monitoring of the electrical output, enabling operators to quickly respond to any issues or faults that might arise in the system.

In contrast, the generator control panel typically houses controls related to the generator's operation, but it does not include the overload protection circuit breaker. The DC instrument panel focuses on the direct current systems, while the utility control panel is often related to interfacing with external power sources rather than handling internal circuit protection.
