Section 1 General

1.1.1 The electrical installation is to be designed, installed and tested in accordance with IEC 60364 Low-voltage electrical installations (relevant parts) or other acceptable and relevant National Regulations or Standards for electrical installations.

1.1.2 A `Completion and Inspection' certificate for the electrical installation verifying that the requirements of the relevant regulations have been met is to be provided to LR by an accredited body before the installation is put in service.

1.2.1 Electrical equipment is, as far as is practicable, to be accessibly placed, clear of flammable material, in well ventilated and adequately lit spaces where flammable gases cannot accumulate and where it is not exposed to risk of mechanical injury or damage from water, oil, etc. Where necessarily exposed to such risks, the equipment is to be suitably constructed or enclosed. Live parts are to be guarded where necessary.

1.3.1 The source of electrical power provided is to have sufficient capacity to supply all electrical services necessary to maintain the facility in the normal operating condition and to have sufficient reserve capacity to permit the starting of the largest motor without causing any motor to stall or any device to fail due to excessive voltage drop on the system.

1.4.1 Means are to be provided, at a location outside the space concerned, for stopping machinery space ventilation fans and oil pumps in the event of a fire.

1.5.1 Electric cables for fixed wiring are to be designed, manufactured and tested in accordance with a relevant IEC Publication or an acceptable and relevant National Standard.

1.5.2 Electric cables exposed to risk of mechanical damage are to be protected by suitable protective casings unless the protective covering (e.g. armour or sheath) is sufficient to withstand the possible cause of damage.

1.5.3 Where electric cables are installed in damp or wet locations or may be exposed to oil or harmful vapours e.g. in machinery spaces, they are to have the conductor insulating materials enclosed in an impervious sheath of material appropriate to the expected ambient conditions.

1.5.4 Electric cables are to be effectively supported and secured, without being damaged, by means of flame retardant clips, saddles or straps.
