This is a standard industrial LV switchboard but specially adapted to function as a training unit. It enables switchgears, instrument and protective gears used in normal switchboard to be demonstrated and their functions explained. It is excellent practice units for students to study its circuitry, dismantle and reassemble component parts rewire. Compartment doors/covers are hinged and can be opened manually by finger-operated screws.
