electrically dangerous, the RCD will switch off the electrical supply and reduce the 
severity of any electric shock received by an operator to a level which, under normal

At least once each month, check that the RCD is operating correctly by pressing the 
TEST button. The circuit breaker 

MUST

 trip when the button is pressed. Failure to 

trip means that the operator is not protected and the equipment must be checked and 
repaired by a competent electrician before it is used.
