Electricians are responsible for the inspection and maintenance of all types of electrical equipment on machinery, in beneficiation 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 are done during training:

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, please feel free to contact CTC's engineering (administration) 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).
