DIN VDE 0661-10 VDE 0661-10:2004-06

This 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. They are intended to provided protection against shock hazard in case of direct contact, in addition to the protection provided by the fixed installations for the circuit downstream.
