required test for electrical installations and electrical products. This test may be referred to as "meggering', after the company Megger was one of the first companies to commercialize an insulation resistance test meter. These days, many other brands are widely available. Earth Continuity Test An earth continuity test checks if a metal part is connected to earth. The resistance of the connection to earth can also be measured. Leakage Current Test A leakage current test detects current that does not flow back through the circuit. This test may be used as part of testing GFCI or RCD operation. Electrical Safety test categories Visual inspection: A survey without touching anything, and looking at the electrical installation or product before starting any electrical testing. A visual inspection seeks to identify damaged insulation, disconnected wires, incorrect installation, and any other visual issues. Non-live testing Continuity test: a test to check the wiring is correct Earth continuity test: this test is to make sure the earthing system is properly connected Live testing Earth fault loop impedance testing: this test is to check that if a fault did occur, that the system meets requirements to cause a disconnection of the supply within the time limit specified by standards Insulation resistance testing Polarity test: a test to check that the connections are connected in the right sequence RCD testing: on modern electrical systems RCD's and RCBO's are regularly fitted, these devices react to electricity leaking from the circuit. Leakage may happen when a person touches live parts, which can cause electricity to passes through their body instead of the normal circuit return path. SPD Test: SPD (Surge Protective Device) is tested as part of the electrical safety test. Surge protection devices safeguard the electrical setup, including the consumer unit, wiring and accessories from dangerous power surges known as transient over voltages. UK specific information Electrical Installation Condition Report An Electrical Installation Condition Report (EICR), more commonly referred to as an EICR Inspection, it is designed to provide a thorough assessment of the condition of electrical installations. This report provides invaluable information to ensure that electrical installation is safe and compliant with current regulations. Since it’s so important, one must understand how long such a certificate lasts before needing another round of testing. An EICR, is a comprehensive inspection and testing of the electrical installation in a building, carried out every 5 years or before the expiry
