To safeguard essential machinery (like steering gear) by automatically disconnecting non-essential services (like AC or galley power) during a partial overload.

Weekly for unloaded battery starts and monthly for automatic start and hydraulic start functionality. Steering Gear Special Requirements

Why use a Megger instead of a Multimeter for insulation?

Cleaning air filters, removing dust from the rotor, checking the air gap (typically 1.5 to 2 mm) with a feeler gauge, and inspecting slip rings and carbon brushes. Safety & Regulations

Steering gear is unique because it must have a short-circuit trip but only an overload alarm (typically at 150%) rather than a trip, to ensure it doesn't stop suddenly during critical maneuvering.

Accept the alarm and isolate breakers one by one to locate the source. Common causes include damaged conductor insulation, dampness, or accumulated dirt. What tasks are performed?
