Protective earth continuity test
Webb3 juli 2024 · This does highlight that in most cases (ie for all circuits using automatic disconnection of supply as the means of fault protection); earth continuity is actually part of EFLI. The key to why measuring just the PEC is deemed adequate testing is that for most circuits the required trip time is 5 seconds. Webb18 nov. 2024 · The purpose of testing protective bonding conductor is to ensure a sufficient earth path, where in the event of a fault the exposed and extraneous conductive parts will have the same potential. That is why it is called ‘equipotential bonding’.

WebbA digital multimeter’s Continuity Test mode can be used to test switches, fuses, electrical connections, conductors and other components. A good fuse, for example, should have continuity. A DMM emits an audible response (a beep) when it detects a complete path. WebbThis device does not protect against electrical shock due to contact with both circuit conductors. Use a GFCI with a trip level of 4 6 mA (USA) resp. a RCD with a trip level of 15 30 mA (Europe). A trip level above 30 mA provides only very limited protection against harm from an electric shock. Danger of burns!
