What is an RCBO and How Does it Work?
RCBO stands for 'Residual Current Breaker with Over-Current'. As the name suggests it protects against two types of fault and in essence combines the functionality of an MCB and RCD.
Let us first remind ourselves of those two faults:
1.Residual Current, or Earth Leakage - Occurs when there is an accidental break in a circuit through poor electrical wiring or DIY accidents such as drilling through a cable when mounting a picture hook or cutting through a cable with the lawn mower. In this instance the electricity must go somewhere and choosing the easiest route travels through the lawnmower or drill to the human causing electric shock.
2.Over-Current takes two forms:
2.1 Overload - Occurs when too many devices are in use on the circuit, drawing an amount of power which exceeds the capacity of the cable.
2.2 Short Circuit - Occurs when there is a direct connection between the live and neutral conductors. Without the resistance provided by the normal circuit integrity, electrical current rushes around the circuit in a loop and multiplies the amperage by many thousand times in just milliseconds and is considerably more dangerous than Overload.
Whereas an RCD is designed solely to protect against earth leakage and an MCB protects only against over-current, an RCBO protects against both types of fault.
