Protective earth continuity test

WebbEarth bond testing verifies the integrity (continuity) of the protective bonding of the equipment designed to secure safety through basic insulation and protective earthing. It is also called the earth (ground) bonding test. With earth bond testing, a current in the range of 5 mA to 100 A is applied for 60 seconds to a few minutes. Webbthe earth continuity test is vital as the safety of the appliance depends upon an ongoing reliable connection with the means of earthing of the fixed electrical installation.
