This part of IEC 60309 applies to three-phase accessories with an earth contact and with four pilot contacts.

NOTE 1 In the following countries the term "ground" is used instead of "earth": US.

These accessories have a maximum rated current of 350 A and a maximum rated operating voltage not exceeding 690 V 50/60 Hz.

NOTE 2 The various operating currents, voltages and frequencies required for various types of ship are set by the shore supply system described in IEC/IEEE 80005-3.

These accessories are intended to be installed and operated by instructed persons (IEC 60050-195:1998, Amendment 1:2001, 195-04-02) or skilled persons (IEC 60050-195:1998, Amendment 1:2001, 195-04-01) only.

This standard applies to accessories for primary use outdoors in a seawater environment when the ambient temperature is normally within the range of −25 °C to +40 °C.

NOTE 3 In some countries, other ambient temperatures may prevail and may need to be taken into account.

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 which is part of the shore connection system are within the scope of this standard.

In locations where special conditions prevail, for example where explosions are liable to occur, additional requirements may be necessary.
