Electrical

Electricians are responsible for the inspection and maintenance of all types of electrical equipment on machinery, in benification plants and buildings, including offices, hostels, houses, etc.

They are also responsible for the distribution of electricity, which includes the laying of cable networks and connection of transformers.

The following modules/unit standards are done during training:

Basic Training


  • Theory:
    Magnetism
    Units and prefixes
    Ohm- and Kirchoff's laws

  • Instruments:
    Use of electrical measuring instruments.
    Testing of cables.
    Determining of the layout of resistance circuits.

  • Buildings:
    Lights and lighting circuits.
    Stove switching.
    Thermostatic controls.
    Construct and wire installations.
    Testing of single-phase installations.

  • Single-phase motors:
    Single-phase motor theory.
    Testing of single-phase motors.
    Connecting a single-phase motor.
    Forward-reverse controlled through a rotary switch and contactors.

  • Three-phase motors:
    Three-phase motor theory.
    Testing of three-phase motors.
    Phasing of induction motors.

      Basic Electronics

  • Soldering of components.
  • Identification of resistors, diodes and inductors and the use there-of.
  • Using an oscilloscope.
  • Construct rectification circuits.
  • Identify and use Zener diodes.
  • Construct a voltage doubler.
  • Identify transistor action and transistor configurations.
  • Test regulated power supplies.
  • Test thyristors and thyristor phase control
  • Explain and apply PLC operating principles.

Final Training


During Final Training, learners receive intensive training to prepare them for the Trade Test. Training during this period includes all modules trained in during the Basic, Advanced and Electronic training phases.

Additional electronic modules can also be completed during this period should his/her company request/require this:

  • Test an amplifier.
  • Using a transistor as a switch.
  • Test multi-vibrators.
  • Identify operational amplifiers.
  • Construct a continuity tester.
  • Test a field effect transistor.
  • Test logic gates.
  • Fault-find circuits.
  • Test electronic systems.
For more information and specific modules/unit standards, please feel free to contact CTC's Electrical Department.

Any part of the course can also be done as per client specification.

The electronic course can also be done as a separate course (see Additional Courses).
