This British Standard specifies requirements for portable residual current devices (portable rods) (including devices using auxiliary sources and devices with electronic circuitry) for operation on an a.c. supply and having a rated voltage not exceeding 250 V a.c. single phase, a rated current not exceeding 16 A, a rated frequency not exceeding 400 Hz and a rated residual operating current not exceeding 30 mA. Portable rods incorporate a plug-pin portion and/or socket-outlet portion(s) and may include terminals for external flexible cords where appropriate. Portable rods with an intentional time delay are not covered by this standard.
