Electrical safety testing that all connections are sound. 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 RCD testing: on modern electrical systems RCD’s and RCBO’s are regularly fitted, these devices react to electricity missing from the circuit or installation such as when a person is receiving an electric shock as the electricity passes through his body to the ground (earth). The competent person will then issue an Electrical Installation Condition Report (EICR) also known as Periodic
Safeguard Program in North Dakota, the Stanley R. Mickelsen Safeguard Complex, became active on 1 April 1975 and fully operational on 1 October 1975.
