Protection against electric shock in household electrical distribution boxes
The fundamental rule of protection against electric shock is provided by the document IEC 61140 which covers both electrical installations and electrical equipment. Hazardous-live-parts shall not be accessible and accessible conductive parts shall not be hazardous. To be considered as providing. The Health and Safety Authority (HSA) has published guidance notes on Periodic Inspection and Testing of Electrical Installations, with suggested time periods between inspection and testing for various workplaces and residential accommodation (on Page 4 of 7). Protection under normal conditions is achieved by basic protection, formerly known as protection against direct contact. The protection classes classify and label electrical equipment to show the safety measures in place to protect against electric shocks. It has the ability to ensure the security of our electrical equipment and protects us from electric shocks, fire or explosion caused by arcing, faulty electrical equipment and installations, and. An electric shock is the pathophysiological effect of an electric current through the human body. The degree of danger for the victim is a function of the magnitude of the.
