Initial verification should follow the BS 7671 edition current at installation, and periodic inspection the edition current at inspection. All testing and commissioning should be done by suitably qualified, competent people (HTM 06-02), with signatories aware of their responsibilities. Periodic testing frequency needs careful planning and communication with affected departments. Verification should show earthing systems comply with BS 7671, supplementary bonding in Group 1 and 2 locations is measured and recorded, and consistent voltages and phase rotation apply throughout including PES and any secondary supply; Section 710 requires additional and more frequent testing.
