Residual Current Devices

Residual Current Devices


Electricity has undoubtedly become an indispensable part of everyday life for everyone. But although it enables us to use thousands of new devices and technologies, it can be hazardous if not treated with caution. The voltage of the electricity used by appliances is enough for them to operate normally, but in many cases it can be lethal to the human body. Everyone must protect against accidental electrical contact and this is the purpose of residual current devices. When they hear of the concept of residual current devices for the first time, many people will probably wonder what it is and if there is any such thing as faulty electricity. Residual current devices are obligatory in practice in order to comply with modern health and safety standards when working with electricity. Below you will find out exactly what residual current devices are and why they are so important for you and your home.
