1. Continuity test: This test checks for any breaks or faults in the electrical circuit by measuring the resistance between different points in the installation. It ensures that all components are properly connected and that electricity can flow freely throughout the system.
2. Insulation resistance test: This test measures the resistance of the insulation material surrounding the electrical conductors. It helps to identify any potential faults or weaknesses in the insulation that could lead to electrical hazards such as short circuits or electric shocks.
3. Earth continuity test: This test checks the integrity of the earth connection in the electrical installation. It ensures that the earth wire is properly connected and provides a safe path for electrical faults to be directed away from the system and into the ground.
4. Polarity test: This test checks the correct connection of live, neutral, and earth wires in the electrical installation. It ensures that the electrical system is properly configured and that electricity flows in the intended direction, preventing potential hazards such as reverse polarity or incorrect wiring.

Four Tests on a Complete Electrical Installation:
1. Continuity Test:
- Verifies electrical continuity of protective conductors (earth and neutral) from the supply point to all exposed conductive parts and equipment.
- Ensures no breaks or excessive resistance in the protective circuits.
2. Insulation Resistance Test:
- Measures the resistance between live conductors and protective conductors (earth and neutral).
- Determines the insulation quality of wiring, equipment, and accessories to prevent electrical leakage.
3. Earth Loop Impedance Test:
- Measures the impedance of the complete earthing system (supply transformer, earthing arrangements, and conductors).
- Verifies the effectiveness of the earthing system in limiting the potential rise in case of a fault.
4. Polarity Test:
- Identifies the phase and neutral conductors in a single-phase or three-phase system.
- Ensures that the correct polarity is maintained to prevent incorrect operation of equipment and possible hazards.
