city and guilds unit breakdown
Unit 201
This unit is the first to complete and comprises of the following sections:
- Identify the legal requirements
- Identify occupational specialisms
- Identify sources of technical information
This is a general Health and Safety unit that also covers some of the fundamentals of the industry, such as the use of drawings.
The second unit and the first one that involves the student thinking more and using their Maths and Physics skills.
- Describe the application of basic units used in electro technology
- Describe basic scientific concepts related to electro technology
- Describe basic electrical circuitry and applications
- Identify tools, plant, equipment and materials
This unit introduces standard units as well as the theory and calculation behind resistance and resistivity and other technical concepts. Ohms Law is introduced at this point.
The third unit is an amalgamation of the first two. It splits Health and Safety and Electrical Principles into two but also requires both parts to be passed independently to achieve the certificate.
- Safe systems of working
- Using technical information
- Electrical machines and a.c. theory
- Polyphase systems
- Over current, short circuit and earth fault protection
Some of the more useful fundamentals of electrical installation are covered, such as protective devices and the purpose of earthing. Motors and a.c. theory also come into play.
This unit also contains Unit 204 which is a practical assessment involving the measurement of 3 phase supplies, both voltage and current and on and off load and the measurement of the different voltages and currents found in a standard fluorescent circuit. This is assessed internally but is needed to claim for your final certificate.
The unit that concludes the level 2 focuses on installation design and Regulations and covers the following subjects.
- Regulations and related information
- Purpose of specifications and data
- Types of installations
- Undertaking electrical installation
As part of unit 205 you have to complete Unit 206, you are expected to complete a large practical task (which can vary centre to centre) that consists of different wiring system such as steel conduit, trunking, swa and lighting and socket outlet circuits.
The start of the level 3 takes all the aspects of level 2 and increases the depth of content. It works in the same way as Unit 203 in that it is split into 2 parts, Health and Safety and Science and Principles and you must achieve a pass in both sections. Expect to cover the following:
- Comply with Statutory Regulations and organisationaI requirements
- Apply safe working practices and follow accident and emergency procedures
- Work effectively and develop competences
and for the second part
- Understand the functions of electrical components
- Understand electrical supply systems, protection and earthing
This unit concentrates on Inspection, Testing and Commissioning and takes the theory up to level 3 where you are expected to test live installations. It is made up of a practical assessment and a 2 hour written examination covering all aspects of Inspection and Testing.
Almost identical to unit 302, this unit concentrates on Fault Diagnosis and Rectification and finishes in a practical assessment and a 2 hour written exam.
