The selected Manual Changeover Switch is to be of similar specification to the examples shown.It must be housed in the appropriate enclose to facilitate cable glanding. The cable used should be SWA and sized appropriately for the supply.The Examiner will provide the candidate with the supplied Electrical Test Record (ETR07).

The Examiner should make available a range of crimp connectors from which the Candidate will need to select
appropriate ones that are fit for purpose to terminate the Manual changeover Switch. The Examiner should make
available a range of Test equipment from which the candidate will select the appropriate ones.

Electrical Installation-Installing Generator Switchgear

Technical Assessment – The candidate is required to install and terminate a manual Double Pole Break - Before - Make changeover switch between a standby generator and the mains supply it is to feed. The switch is to be installed as per the manufacturer’s specifications, the candidate is to configure the generator supply to a Neutral - Earth configuration

Objective - To ensure a candidate has the skills, knowledge and ability to install and terminate a manual Double Pole Break – Before _ Make changeover switch to ensure that the generator supply does not transferto the grid and the mains supply does not back feed the generator. The candidate is to carry out testing and function checking, all work to comply with the regulations and recognised industry practices.

The candidate must install manual changeover switch in accordance with manufacturer’s specifications. It is deemed appropriate that for the purpose of this test the incoming mains supply is simulated. The designed test area must have good lighting and be away from any production area. The Examiner must ensure that the candidate has completed the installation and tests to specification and following established working practice.

The Examiner must supply the necessary equipment required for the installation a drawing shall be provided by the examiner and the manufacturers specification for the selected Double pole Break - Before - Make Manual changeover switch. The candidate is expected to arrange the termination of the circuit following recognised industry practices.

The candidate is expected to complete the test, being observed using correct installation, termination, testing and function checking techniques, to produce the two way and intermediate switching arrangement for the changeover switch and apply safe working practices to achieve a ‘PASS’. Where the candidate does not achieve the set criteria this is recorded as ‘REFERRED’ and a brief note recorded on the criteria not met in the test activity.

The candidate must record a PASS in all practical test sections and score a minimum of 80% in the multiple choice section.
