This International Standard applies to portable devices for household and similar uses (hereafter referred to as portable residual current devices (PRCDs), consisting of a plug, a residual current device (RCD) and one or more socket-outlets or a provision for connection, functionally independent of, or functionally dependent on, line voltage. They do not incorporate overcurrent protection. They are intended for single-phase circuits for rated currents not exceeding 16 A for rated voltages not exceeding 250 V a.c., or for rated current not exceeding 32 A for rated voltages not exceeding 130 V a.c. to earth. They are intended to provide protection against sho
