Book excerpt: This standard specifies the classification, characteristics, marking and product information, standard conditions for operation and installation in service and for installation, requirements for construction and operation and tests of portable devices for household and similar uses. This standard applies to 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 16A for rated voltages not exceeding 250V a.c. They are intended to provide protection against shock hazard in case of direct contact, in addition to the protection provided by the fixed installations for the circuit downstream.
