An RCD in Lehman terms is your electrocution protection!
Circuit breakers are there to protect the cable and trigger in the case of short circuit or overload, but won’t protect you from electric shock!
The difference between a circuit breaker and RCD – See pictures below.
Circuit breaker ( No test button)
RCD/RCBO with test button (Safety Switch)
Residual Current device or RCD – How it works?
Electricity from your switchboard will flow:
Through the Active cable
Through your appliances’ element (TV’s, Toasters, Kettles, Hairdryers etc)
Then back to your switchboard via the neutral cable
If a fault occurs it will flow through the earth cable to the ground or through a person to ground if touched… This is where an RCD is vital.
An RCD checks that the current flowing through the live wire is the same as the current flowing back on the neutral wire.
There are two types of RCD
Residual Current Circuit Breaker
Residual Current Circuit Breaker with Overload Protection.
