RCCBs Type AC Selective

Type AC residual current

Regulation 531.3.3 Tripping on:

  • 50Hz sinusoidal AC

Note: Type AC RCDs are not suitable for use in circuits powering electronically controlled equipment.

Type AC RSDs must not be connected upstream of Type A, F, B or EV RCDs.

Selectivity between RCDs see Regulation 536.4.1.4 (ii).
