NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:
.3 Short-circuit protection and an overload alarm shall be provided for steering gear electric and electro-hydraulic circuits and motors. Protection against excess current, including starting current, if provided, shall be for not less than twice the full load current of the motor or circuit so protected, and shall be arranged to permit the passage of the appropriate starting currents. The alarms required in this paragraph shall be both audible and visual and shall be situated in a conspicuous position in the main machinery space or control room from which the main machinery is normally controlled and as may be required by Regulation 6 of Part E of this chapter. .4 When an auxiliary steering gear required by Regulation 6.3.3 to be operated by power is not electrically powered or is powered by an electric motor primarily intended for other services, the main steering system may be fed by one circuit from the main switchboard. Where such an electric motor primarily intended for other services is arranged to power such an auxiliary steering system, the requirements of paragraph .3 may be waived by the Administration of the flag State, if satisfied with the protection arrangement together with the requirements of Regulation 6.4.1 and 6.4.2 applicable to auxiliary steering systems.
