The document provides instructions for testing electrical circuits without power (dead testing) and insulation testing. It describes checking visual connections, continuity testing between phases, and insulation testing between live conductors and earth. Connection tightness, cable colors, sizes and labeling are checked visually. Continuity tests are done between lamp circuits, sockets, and earth connections. Insulation testing measures resistance between live conductors and earth/metalwork to check for faults. Readings below 1MΩ indicate failure.Read less
