    ring final circuit conductors comes under the same test as continuity, continiuty of conductors are to include protective conductors including main and supplementary bonding conductors, also ring final circuit conductors including protective conductors..

    I wouldn't count visual inspection in the sequence of tests. They are completely seperate, hence why they call it Inspection AND Testing.

    Inspection is done using the senses. Testing is done using test equipment.
