This fundamentals-of-electrics course provides a basic understanding of electrical principles, safe isolation techniques. It equips participants with the knowledge and skills to replace like-for-like electrical components safely and responsibly in a domestic environment. It will provide the basic electrical knowledge and terminology to people wishing to progress to the City and Guilds 2377-22 Certificate for Inspection and Testing of Portable Equipment.
Revision and home study will be an important part of this course.
Benefits to you
On completion of this course participants will understand:
- The basic electrical parameters (voltage, current, resistance), their units of measurement (volts, amperes, ohms) and inter-relationship (Ohm’s Law).
- Be able to relate these parameters to the basic electrical circuit and series and parallel circuit configurations.
- Understand the difference between continuity and insulation resistance, know how to calculate electric power and energy consumption, and understand the information marked on equipment for rating purposes.
- Understand the characteristics of and differences between direct current (d.c.) and alternating current (a.c.), understand the need for electrical protection, the types of abnormal condition for which protection is required, the types of protective device available for use and method of operation and be able to select a protective device of the correct type and rating.
- Understand the principles of earthing and the need for and difference between switching and isolation, including the characteristics of such devices and the importance of correct polarity.
- Have an awareness of the different supply arrangements (LV and HV) to work premises and the arrangement of building electrical installations.
