"This part of IEC 62613 applies to accessories with ? three phases (3 poles and Earth) with up to three pilot contacts@ ? one single pole (Neutral). These accessories have rated currents not exceeding 500 A and rated operating voltages not exceeding 12 kV 50/60 Hz. NOTE 1 In the USA@ the term ""Ground"" is used instead of ""Earth"". These accessories are primarily intended for use outdoors@ in a seawater environment@ for the shore supply of ships (ship-to-shore connection)@ in an ambient temperature within the range of -25 ??to +45 ?? NOTE 2 In some countries@ other ambient temperatures may prevail and may need to be taken into account. These accessories are not intended for use in hazardous areas. In such locations where special conditions prevail@ additional requirements may be necessary. These accessories are intended to be connected to cables of copper or copper alloy only. Socket-outlets or ship inlets incorporated in or fixed to electrical equipment are within the scope of this standard."
