Mechatronics Certification Tests

Mechatronics Certification Test - Industrial Electricity 1

This certificate covers basic safety practices for voltages up to 600 volts and knowledge of voltage, current and power in AC and DC circuits, circuit analysis of series and parallel loads, and basic understanding of resistors, capacitors, and inductors. It applies these fundamentals to simple applications that would be found in residential, light commercial and simple industrial use. Candidates should be able to interpret and troubleshoot circuits used for lighting, across the line 3 phase motor starting, and simple relay logic with devices such as control transformers, fuses & circuit breakers, pushbuttons & selector switches, pilot lights & alarm devices, solenoids, 3 phase motor starters, motor overloads, limit switches, and combinations of control relays to perform basic logic functions. Candidates should be familiar with simple wiring practices for using these devices and with component level troubleshooting of these devices.

A basic knowledge of industrial electricity is needed to understand the basic operation of all type of commercial and industrial equipment and to gain further knowledge of more complex packaging machines and systems.

This basic knowledge of industrial electricity would be expected of an entry level electrician working in facilities maintenance or assisting in the assembly, test, startup, troubleshooting, maintenance, repair or upgrade of basic packaging machinery modules.
