An example of some parameters inspected but not limited to:

​

• Testing of main earthing resistance and record results.

• Earth testing will be carried out on the main earthing system within the main switchboard and at the main earth electrode.

• Test all connections for continuity and resistance.

• Measure leakage current in the main neutral and earthing system.

• Any additions or changes checked to ensure they are adequately connected to the lightning protection system.
