Why use Miniature RCBOs?
RCBO (Residual Current Circuit Breakers with Overcurrent Protection) devices are a combination of an RCD (Residual Current Device) and MCB (قواطع دوائر مصغرة) in one.
An RCD detects Earth Leakage, i.e. current flowing where it shouldn’t, switching the circuit off where there is an Earth fault current. The RCD element of the RCBO is there to protect people.
In housing installations it’s not unusual to find that one or more RCDs are used alongside MCBs in the consumer unit, all grouped together protecting multiple circuits. What commonly happens when there is an earth fault on one circuit is that a whole group of circuits, including healthy circuits, are switched off.
In these instances, using RCDs and MCBs in groups goes against specific aspects of the IET’s 17th Edition Wiring Regulations. Specifically, Chapter 31-Division of Installation, regulation 314.1, which requires every installation to be divided into circuits as necessary –
1)To avoid danger in the event of a fault
2)To facilitate safe inspection, testing and maintenance
3)To take account of hazards that might arise from the failure of a single circuit e.g. lighting circuit
4)To reduce the possibility of unwanted tripping of RCDs (not due to fault)
