City & Guilds 2377

Synopsis

Rationale for City & Guilds 2377 One-Day Course This City & Guilds course provides an overview of the latest edition of the IET Code of Practice for InService Inspection & Testing of Electrical Equipment. The Code of Practice (COP) provides guidance on the inspection and testing of electrical appliances, luminaires, IT equipment supplied by a plug and socket, and similar equipment connected by a flexible cord. The COP is written both for administrators with responsibility for electrical maintenance (who may have little technical knowledge) and the staff who carry out the inspections and tests. This course prepares candidates for the multiple-choice exam for 2377 certification. The exam comprises a 30-question multi-choice test lasting 1 hour. It is set and marked by City & Guilds, but run by Trans-Euro Engineering Services Ltd in Towcester.

Objectives The objectives of the course are for the participants to: •

Understand the legal requirements for maintenance of electrical equipment.

Be able to select suitable frequencies of maintenance and know the requirements for record keeping and training of personnel.

Know the construction and classification of electrical equipment.

Be able to identify different types of test equipment.

Be capable of inspecting electrical equipment and identifying potential faults.

Know the tests to perform on different classes of equipment.

Administrative Arrangements The course and the exam are normally held at Trans-Euro’s premises at 186 Watling Street, Towcester, but the location can be at client premises by prior arrangement. Normal times of attendance are from 09:00 to 17:00, with a 45-minute break for lunch. Depending on the number of delegates on the course, the online exam may not be complete until 18:00. Refreshment breaks are taken as necessary during the mornings and afternoons. Towcester is centrally placed and is conveniently accessible by road, rail and air. Accommodation and parking are easily arranged. Full details are available from the Course Secretary. Participants with special needs should advise the Course Secretary 21 days before the start of the course.

Safety Warning Note that the Trans-Euro emergency assembly area is the Magistrate’s Court car park, across the main A5 Watling Street. This is a busy trunk road therefore extreme caution is required.

Equal Opportunities Trans-Euro supports equal opportunities in education, training and employment, and takes positive action to achieve this.

Synopsis

We are committed to giving delegates who want to gain an award an equal opportunity of achieving it irrespective of age, gender, sexual orientation, race, religion, physical abilities, learning capabilities, eyesight, hearing etc in line with current UK legislation and EU directives. Delegates with impairment(s) should make their requirements known in advance of booking courses in order to provide time for specialised staff external to the Centre to be made available to assist and for additional exam time to be sought where appropriate, eg for dyslexic or deaf delegates. The formal, detailed, Trans-Euro Equal Opportunities Policy statement is available on request, held by the Course Secretary.

Disclaimer Achieving the C&G 2377 qualification does not provide any guarantee of workmanship, performance, quality or status of the candidate during future endeavours such as plying his/her trade, applying for membership/enrolment of trade bodies/institutions, or for job seeking etc Course Framework The course is divided into 6 sections: •

Structure of the COP

Construction and classification of equipment

Inspection and Testing

Part 3 of the COP - Appendices
