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 Safeguard Program The Safeguard Program was a U.S. Army anti-ballistic missile (ABM) system designed to protect the U.S. Air Force's Minuteman ICBM silos from attack, thus preserving the US's nuclear deterrent fleet. It was intended primarily to protect against the very small Chinese ICBM fleet, limited Soviet attacks and various other limited launch scenarios. A full-scale attack by the Soviets would easily overwhelm it, a deliberate point to ensure the Soviets did not consider it a strategic threat. It was designed to allow gradual upgrades to provide similar lightweight coverage over the entire United States over time. Safeguard was the
