8B Electrical Installations - Vessels of 500GT and Over

Objective:- This section outlines the minimum requirements for electrical installations, which are to be in accordance with the requirements of one of the Classification Societies defined in the National Annex, and should cover the minimum aspects defined below. For sailing vessels, this should also cover the elements necessary to ensure safety of the vessel including control of the sails, where appropriate.

8B.1 The electrical equipment and its installation should meet the standards of SOLAS Chapter II-1/Part D - Electrical installations and II-1/Part E - Additional requirements for periodically unattended machinery spaces, where appropriate, so far as it is reasonable and practicable to do so.

8B.2 The emergency generator, if fitted, should be located above the uppermost continuous deck but may be located below this deck provided it is protected from the effects of fire and flooding. In all cases, the emergency generator should be separated from main generators and main switchboard by a division capable of ensuring its continued operation. The emergency generator should be self contained (independent of a sea water suction) and readily accessible from the open deck.

8B.3 Cables and wiring serving essential or emergency power, lighting, internal communications or signals should be routed clear of galleys, machinery places of Category A and their casings, spaces for storage of petrol, and other high risk fire areas.
