Will my safety switch always protect me?
A safety switch will turn off the power in a fraction of a second if a leakage of current to "earth" is detected. This can happen if there is a faulty power point or electrical appliance or you accidentally hit a live wire, but there may be instances where it doesn't operate if a person is not earthed. So even if you have safety switches fitted, it is important to only use electrical equipment that is in good working order and only in accordance with the manufacturer's instructions. Always check for signs of damage and never attempt your own electrical repairs. Damaged electrical equipment and appliances should either be disposed of or repaired by an authorized service agent or licensed electrician. To ensure a safety switch continues to work correctly, you should self-test your safety switch test every three months. It cannot protect you if it is not working properly. Regular testing is the best way to ensure that it continues to work.
