1. Do you know the reason for ground- Provides safety and stability to the entire electrical
ing? network
2. Can you name the common stan- 1. Prevent electrical equipment from contacting wet
dards associated with electrical con- areas
trol? 2. Ensure safe use when unplugging
3. Install properly and tidy electrical cords
4. Understand your switchboard
5. Look out for electrical lines
6. Childproof your outlets
7. Investigate Flickering Lights
8. Install warning lights
9. Don't DIY
10. Call for help
3. Can you perform, in proper order, the 1. Notify affected employees
lockout/tagout system? 2. Identify procedure and hazards
3. Shut down
4. Isolate machine from energy source
5. Apply lockout tagout devices
6. Check stored energy
7. Verify isolation, Tryout and Test
8. Bring equipment back on line
4. Can you explain the operation of Provide three separate currents separated by
three-phase power? one-third of the time it takes to complete one cycle
5. Do you know the function of neutral Energy converted from other forms of energy to
in electric power? create lighting, computer operation, motive power,

probe into the correct jack, or you will blow a fuse in
your multimeter
7. Can you explain the operation of In a solidly grounded system we assume the fault
grounded and ungrounded systems? occurs but have to take the necessary stepd to avoid
further damage. In an ungrounded system, a fault
does not interrupt the system power supply and
does not increadse the availability of the system
8. Do you know how different types of Fuses, breakers, and others limit the current to the
overcurrent protection devices work? proper rate and disconnect short circuits
9. Do you know how a three-phase mo- It uses a three-phase power supply to convert elec-
tor works? trical energy into mechanical energy
10. Can you interpret the data on a mo- A nameplate has information on the construction
tor's nameplate? of and characteristics of the motor. It carries infor-
mation such as number of phases, rated operating
voltage, service duty, efficiency code, frame size, IP
rating, installation class and more
11. Can you connect a dual-voltage Under the lid of the motor's terminal connections is a
three-phase motor for high and low wiring diagram. For high voltage the motor is wired
voltages? in Star and it will stay that way
12. 2 Manual Motor Control and Over- The overload relay is wired in series with the moor so
load Protection the current that flows to the motor when the motor
is operating also flows through the overload relay
13. Can you state the five functions of Starting and stopping the motor, controlling the di-
motor control? rection and speed, regulating torque, protecting the
motor, providing feedback, ensuring efficiency, load
matching, and including safety measures
