For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defined in this clause.’2
accommodation spaces: Spaces provided for passengers and crew members that are used for berthing. dining rooms, mess spaces, offices, private baths, toilets and showers, lounges, and similar spaces.
adjustable speed drive (variable frequency drive): A converter using solid state switching devices that has the capability of adjusting the frequency and voltage of the output waveform to provide speed and torque control of motors.
communication and electronics circuits: Electrical circuits supplying equipment and systems for voice. sound. or data transmission, such as telephone, engine order telegraph, data communication, interior communication, paging systems, wired music systems, fire and general alarm systems, smoke and fire detection systems, closed circuit television, navigational equipment, and microprocessor-based automated alarm and control systems.
deluge: A condition where equipment is exposed to an abnormal volume of water during extreme weather, testing, maintenance, or fire suppression.
double banked: The arrangement of cables in a cable tray or raceway wherein the cables arc stacked in two layers.
feeder: A cable or set of conductors that originates at a main distribution center (main switchboard) and supplying secondary distribution centers, transformers, or motor control centers. (Bus tie circuits between generator and distribution switchboards, including those between main and emergency switchboards, are not considered as feeders.)
hydrocarbon pool fire: A fire that occurs when a flammable liquid leaks from a vessel or pipeline to form a fluid reservoir, which then ignites.
intrinsically safe circuit: A circuit in which any spark or thermal effect is incapable of causing ignition of a mixture of flammable or combustible material in air under prescribed test conditions.
lug: A wire connector device to which the electrical conductor is attached by mechanical pressure or solder.
machinery spaces: Spaces that are primarily used for machinery of any type, or equipment for the control of such machinery, such as boiler, engine, generator, motor, pump, and evaporator rooms.
multicable penetrator (multicable transit NICT): A device consisting of multiple nonmetallic cable seals assembled in a surrounding metal frame, for insertion in openings in decks, bulkheads, or equipment enclosures and through which cables may be passed to penetrate decks or bulkheads or to enter equipment without impairing their original tire or watertight integrity.
NRTL: A nationally recognized testing laboratory as recognized by the U.S. Occupational, Safety, and Health Administration (OSHA) or the Authority Having Jurisdiction.
single banked: The arrangement of cables in a cable tray or raceway wherein the cables are installed in a single layer with a spacing of less than one cable diameter.
switchboard: A metal-enclosed panel or assembly of’ panels that may contain molded case, insulated case or power circuit breakers, bolted pressure contact or fusible switches, protective devices, and instruments. These devices may be mounted on the face or the back of the assembly. Switchboards are generally accessible from the rear as well as from the front; however, they can be front accessible only.IEEE Std 45.8 pdf download.
