Testing
On completion of the visual inspection the following tests must be completed where applicable: They must be carried out in the following order.
Tests before connection of the installation to the supply:
1. Continuity of all protective conductors.
2. Continuity of ring final circuit conductors ( Step 1 covered at Phase 2 ).
3. Insulation Resistance of the electrical installation.
4. Protection by separation of circuits ( not covered at Phase 2 ).
5. Floor and wall resistance ( not covered at Phase 2 ).
6. Polarity test.
7. Electrical strength test ( not covered at Phase 2 ).
Tests after connection of the installation to the supply
1. Automatic disconnection of supply including earthing and bonding ( not covered at Phase 2 ).
2. Functional tests ( not covered at Phase 2 ).
If the installation should fail any test, the fault must be rectified before any further testing is done. That test and any preceding tests that may have been affected by the fault, should now be repeated. If all is satisfactory continue with testing as above.
