DESIGN of ELECTRICAL INSTALLATIONS
(CITY & GUILDS 2391-20 - PREVIOUSLY KNOWN AS C&G 2400)
COURSE 350: 4 DAYS + examinations + project
Whenever electrical systems are installed, the correct design of the installation will be paramount for ensuring the safety of personnel and the ongoing functionality of the installation itself. Even when fairly straight-forward installations are carried out, there is always a level of design work required - for instance in a small domestic installation it may be necessary to calculate the size of cable feeding a garage which is a long distance from the house. In larger commercial installations the ‘standard circuits’ often employed in small installations are no longer applicable, and each circuit would need design calculations to be performed. This course provides participants with all the necessary skills and knowledge to design electrical installations.
PARTICIPANTS
The course is intended for candidates who have already attended the 17th Edition / C&G 2382 (Course 310 or 300) and the Inspection & Testing / C&G 2391-10 (Course 340). The course builds on the knowledge and skills that candidates have gained from these courses.
COURSE PRESENTATION
Instructor-led practical examples of how electrical installations should be designed are given. The course consists of several design exercises for the candidates to carry out. A range of electrical installations from small domestic circuits to more complex commercial and industrial examples are used. Comprehensive course notes are provided.
COURSE OBJECTIVES
On completion of the course, participants will be able to
- design electrical installations, performing all necessary calculations
- verify that a design complies with the Regulations
- conduct an initial verification of a new electrical installation
- conduct an initial inspection of an electrical installation
- design, verify and inspect electrical installations in compliance with current safety legislation and BS7671.
Candidates are required to complete a 20-hour design project which involves the assessment of general characteristics, selection and erection and verification of an electrical installation.
Successful completion of the course leads to the award of City & Guilds 2391-20 Level 3 Certificate in Design, Erection and Verification of Electrical Installations.
