A new installation is to be installed with a circuit that utilises a transformer. The protection method on the load side is by electrical separation, what must be done to confirm the separation of the live parts from other circuits?

• a)       Confirm with the equipment manufacturer
• b)        Perform a continuity test between the supply and load sides
• c)         Perform a phase sequence test
• d)        Perform an insulation resistance test

Which one of the following options is not the purpose of periodic inspection and testing?

• a)       Ensure safety of persons and livestock against the effects of electric shock
• b)        Ensure protection is provided against damage to property by fire from an installation defect
• c)        To ensure the installation performs to the requirement of the owner
• d)       To ensure confirmation the installation is not damaged so as to impair safety

After a new electrical installation has been installed in a property, the installation shall be inspected and tested to verify that the requirements of the Regulations have been me. The verification shall be made by?

• a)        The distribution network operator
• b)        A skilled person competent in such work
• c)        The architect
• d)        The client

Where an additional socket outlet is added to an existing circuit in a domestic property, which certificate is issued?
