City and Guilds Inspection and Testing Courses

The qualification is in two parts, a three hour written examination and a design assignment, carried out after the course.

The five-day course will provide the candidate with all the necessary information and knowledge to design an electrical installation; the focus being on cable sizing, routing and management, taking account of environmental influences.

Design calculations will be carried out manually but the use of software cable sizing packages will be discussed. During the course, a typical new commercial installation will be used as the basis for the design of an electrical system using architects' drawings.

Overlays will be used to indicate proposed cable routing using British Standard symbols and cables will be selected to be suitable for electrical environmental and aesthetic conditions.

Design calculations will be produced to validate the disconnection time for each circuit to comply with the wiring regulations. This will allow the person responsible for inspection and testing to compare actual values with design values. Time will also be given to the assignment structure.

The assignment will be started during the course but candidates will be given 2 months to complete it. It is expected to take candidates 40 hours and email communication with the tutor is required during that time.

The course fee includes City & Guilds examination fees, administration costs for the assessments, lunch, refreshments and course notes.

Prospective candidates should have a minimum of City & Guilds 2382; as during the course it will be assumed you are already familiar with the technical language and have a working knowledge of BS 7671 2008. They should also hold theCity & Guilds 2391-10/2394-01/2395-01 Testing and Inspection qualification.

Candidates will be required to bring a copy of The IEE Electrical Installation Design Guide ISBN: 978-0-86341-550-0
