What is the main purpose of an Initial Verification?

• To confirm an installation is safe to be put into service

• To complete the testing and issue an Electrical Installation Certificate

• To ensure all testing has been carried out

• To make a judgement that the installation is safe for continued use

What situation requires the issuing of a Minor Electrical Installation Works Certificate?

• An additional lighting circuit has been installed

• Additional socket-outlets added to an existing ring final circuit

• Changing a consumer unit and protective devices

• Upgrading the cable and circuit breaker for a shower circuit

Which statutory document contains specific information relevant to Initial Verification?

• Health and Safety guidance GS38

• The Electricity at Work Regulations

• BS 7671, Requirements for Electrical Installations

• The Health and Safety at Work Act

What is the minimum voltage which requires the test leads and probes to comply with GS38?

• 120 V AC

• 25 V AC

• 50 V AC

• 150 V AC

How many voltage measurements are required to confirm that a three-phase four-wire installation is safely isolated?

• 9

• 10

• 6

• 3

What precaution is required before carrying out a test of external earth fault loop impedance (Ze) so as to avoid danger to users of an installation?

• Lock off the supply

• Disconnect the main protective bonding conductors

• Use insulated screwdrivers

• Warn the occupier of the premises

Why does BS 7671 require inspection to be carried out before testing?

• To confirm the Earthing Conductor is connected and it is safe to commence testing

• To confirm the installers have installed as per the job specification

• To confirm the installation is complete and it is safe to commence testing

• To confirm all the equipment is connected to the installation will work

Which situation will not require a label stating 'Safety Electrical Connection – Do Not remove'?

• Connecting a bonding conductor to a metallic installation gas pipe

• The connection to a Main Earthing Terminal within a consumer unit

• A supplementary bonding conductor connected to a metallic water pipe

• An Earthing conductor connected to an installation earth electrode

What must be checked when inspecting a consumer unit for compliance with Basic Protection requirements?

• Live conductors are correctly identified

• Enclosures meet the IP requirements

• Protective devices are the correct rating

• All cable terminations are tight

Which two senses are used when inspecting the terminations at a newly installed motor?

• Touch and smell

• Touch and sight

• Sight and smell

• Sight and hearing
