An extension cord with a small cut in the outer insulation is okay to use because the internal insulation is not damaged.
- A.
TRUE
- B.
FALSE
Correct Answer
B. FALSEExplanation
An extension cord with a small cut in the outer insulation is not okay to use, even if the internal insulation is not damaged. The outer insulation is responsible for protecting the internal wires from physical damage and exposure to moisture. A cut in the outer insulation can increase the risk of electrical shock or fire hazards. It is important to replace or repair any damaged extension cords to ensure safety.Rate this question:

Twist lock style cord heads should be used on our projects.
- A.
TRUE
- B.
FALSE
Correct Answer
A. TRUEExplanation
Twist lock style cord heads should be used on the projects. This implies that using any other type of cord heads may not be suitable or safe for the projects. Therefore, the correct answer is TRUE, indicating that twist lock style cord heads should be used.Rate this question:

What must be covered in an assured grounding program?
- A.
All cords not protected by a GFCI
- B.
Only equipment that could shock you
- C.
Underground cords and wires
- D.
Cords that run through high traffic areas
Correct Answer
A. All cords not protected by a GFCIExplanation
An assured grounding program should cover all cords that are not protected by a Ground Fault Circuit Interrupter (GFCI). This means that any cords that do not have the necessary protection against electrical shocks should be included in the program. This ensures that all potential hazards are identified and addressed, reducing the risk of electrical accidents or injuries.Rate this question:

GFCI's measure a difference or leakage in current. The GFCI will open the circuit thus stopping the current flow when it detects a leakage of more than ___ mA?
Correct Answer
5Explanation
GFCI's, or Ground Fault Circuit Interrupters, are electrical safety devices that are designed to protect against electrical shock. They work by constantly monitoring the flow of current in a circuit. If the GFCI detects a difference or leakage in current, it opens the circuit and stops the current flow. In this case, the correct answer is 5 mA, meaning that the GFCI will open the circuit when it detects a leakage of more than 5 milliamperes.Rate this question:

When should documented testing take place for a GFCI?
- A.
Daily
- B.
Monthly
- C.
Quarterly
- D.
When something breaks
Correct Answer
B. MonthlyExplanation
Documented testing for a GFCI should take place monthly. This is important to ensure that the GFCI is functioning properly and providing the necessary protection against electrical shocks. Regular testing helps to identify any faults or malfunctions in the GFCI, allowing for timely repairs or replacements. Monthly testing also helps to maintain compliance with safety regulations and standards.Rate this question:

What is the only type of cord we can use that is not 3 wire?
- A.
The one that is made out of bailing wire and duct tape.
- B.
Double insulated
- C.
The one that we made from Christmas lights
- D.
S type 18 gauge
Correct Answer
B. Double insulatedExplanation
Double insulated cords are the only type of cords that can be used that are not 3 wire. Double insulation refers to a safety feature in electrical cords where an extra layer of insulation is added to provide an additional barrier of protection. This type of cord is commonly used in appliances and power tools to prevent electric shocks and reduce the risk of electrical fires.Rate this question:

Why is it important to have a grounding conductor on all electrical cords?
- A.
Helps protect the person using the cord from electrical shock
- B.
Helps route current through the supplied ground instead of the person
- C.
It looks way cooler than the two wire type
- D.
Current will always take the path to ground with the least resistance
- E.
It is a good way to protect our employees
Correct Answer(s)
A. Helps protect the person using the cord from electrical shock
B. Helps route current through the supplied ground instead of the person
D. Current will always take the path to ground with the least resistance
E. It is a good way to protect our employeesExplanation
A grounding conductor is important on all electrical cords because it helps protect the person using the cord from electrical shock. It helps route current through the supplied ground instead of the person, ensuring their safety. Additionally, current will always take the path to ground with the least resistance, so having a grounding conductor ensures that the path of least resistance is through the ground rather than through the person. Having a grounding conductor is also a good way to protect employees who may be using the cord, further emphasizing its importance.Rate this question:

18 gauge wire is larger than 12 gauge wire?
- A.
TRUE
- B.
FALSE
Correct Answer
B. FALSEExplanation
The statement is false because wire gauge is inversely proportional to the size of the wire. The smaller the gauge number, the larger the wire size. So, 12 gauge wire is actually larger than 18 gauge wire.Rate this question:

Most of our heavy equipment is not insulated which means what?
- A.
Damage to the equipment could be catastrophic
- B.
The ground beneath the equipment may be energized
- C.
You should stay in the equipment if you contact overhead power lines
- D.
The only time you should exit the equipment before the line is de-energized is if the equipment catches fire
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
The correct answer is "All of the above". This means that all of the statements mentioned in the options are true. If heavy equipment is not insulated, it can lead to damage that could be catastrophic. Additionally, the ground beneath the equipment may be energized, posing a risk of electric shock. It is generally safer to stay inside the equipment if you come into contact with overhead power lines. However, if the equipment catches fire, it is advisable to exit the equipment before the power line is de-energized.Rate this question:

The severity of a shock depends on what?
- A.
The path of the current through your body
- B.
The amount of current (amps)
- C.
The duration of the shock
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The severity of a shock depends on all of the mentioned factors. The path of the current through the body determines which organs or tissues are affected and how deeply the shock penetrates. The amount of current, measured in amps, determines the intensity of the shock and the potential damage it can cause. Lastly, the duration of the shock also plays a role in determining the severity, as longer exposure to the current can lead to more severe injuries.Rate this question:
