Artikel 54

(1) (a) Where electrical power constitutes the only means of maintaining auxiliary services essential for the propulsion and the safety of the vessel, a main source of electrical power shall be provided which shall include at least two generating sets, one of which may be driven by the main engine. The Administration may accept other arrangements having equivalent electrical capability.
(b) The power of these sets shall be such as to ensure the functioning of the services referred to in Regulation 41(6)(a), excluding the power required in fishing activities, processing and preservation of the catch, in the event of any one of these generating sets being stopped. However, in vessels of less than 45 metres in length, in the event of any one of the generating sets being stopped, it shall only be necessary to ensure the functioning of services essential for propulsion and safety of the vessel.
(c) The arrangement of the vessel's main source of electrical power shall be such that the services referred to in Regulation 41(6)(a) can be maintained regardless of the number of revolutions and direction of the main propelling engines or shafting.
(d) Where transformers constitute an essential part of the supply system required by this paragraph, the system shall be so arranged as to ensure continuity of the supply.

(2) (a) The arrangement of the main lighting system shall be such that a fire or other casualty in the space or spaces containing the main source of electrical power, including transformers, if any, will not render the emergency lighting system inoperative.
(b) The arrangement of the emergency lighting system shall be such that a fire or other casualty in the space or spaces containing the emergency source of electrical power, including transformers, if any, will not render the main lighting system inoperative.
