*if fitted.
In the event of a fault or overload, the MCB will 'trip' i.e. , automatically
moves to the 'OFF' position.
After elimination of the fault the MCB can be re-set by switching to the 'ON'
(up) position, against the spring pressure, in an upwards direction.
Earth Leakage Fault:
If an earth fault develops or a person were to touch a live piece of
equipment the leakage of current to earth should immediately operate the
RCD and 'trip' the main switch to the off position.
The switch is only re-settable after elimination of the fault.
To re-set, switch the RCD switch to the 'ON' (up) position.
