• Insulation resistance tests are necessary to ensure that the insulation resistance between all live conductors and earth or, as the case may be, all live parts and earth is adequate to ensure the integrity of the insulation. This is to prevent electric shock hazards from inadvertent contact, fire hazards from short circuits and equipment damage. In addition, insulation resistance tests between all live conductors are necessary to minimise the potential for insulation breakdown, injury or property damage due to the failure of such conductors.

• Polarity testing is necessary to ensure that no shock hazard results from the incorrect connection of active, neutral and earthing conductors. This testing is to ensure active and neutral conductors of the consumers mains and submains are not transposed resulting in the electrical installation earthing system becoming energised. Additionally, that there are no combinations of incorrect active, neutral and earthing conductor connections resulting in the exposed conductive parts of the electrical installation becoming energised. Finally, that switches do not operate in neutral conductors, resulting in parts of appliances, such as heating elements and lamp-holders, remaining energised when the switches are in the "OFF" position.

• Exception: Multi-pole RCDs, multi-pole switched in which the neutral is switched and switches in the control circuit of fire pumps

• Phase sequence testing is necessary to ensure that multi-phase equipment operates in a predictable manner, e.g. multi-phase motors, semi-conductor controlled equipment
