The function of a safety switch is to protect against
electrocution and therefore save lives by detecting a
leakage of current to earth. They are usually calibrated to
trip at 30mA of earth leakage with a tripping time of
1millisecond.
But it is not a substitute for common sense and we must
always remember to be safe with electricity, never use
appliances with frayed or damaged leads. If an appliance is
identified as faulty do not use it until it has been
repaired by a qualified person.
To restore the power if your safety switch has tripped
follow this suggested sequence:
Please remember that a safety switch is a Safety Device.
You should:
- never use appliances suspected to be faulty;
- always practice safe use of appliances;
- never use appliances near water.
Test your safety switch every month to ensure it is
working, by pressing the test button, this simulates an
earth fault!
