Aside from high-voltage systems, what other application can insulated hand tools be used on?

  • No other application

  • Any general repair

  • Non-high-voltage repairs

  • Household repairs

Correct answer: No other application

Insulated tools are only designed to be used on high-voltage systems. They aren't intended to be used in any other repair application. 

Technicians should have insulated hand tools for work with high-voltage systems and other tools for non-high-voltage repairs. 

62.

Which of the following IP ratings means the tool is dustproof and waterproof?

  • IP68

  • IP64

  • IP36

  • IP24

Correct answer: IP68

The Ingress Protection (IP) rating includes two digits. The first digit indicates how much dust is prevented, while the second number indicates water protection levels. 

For the tool to be considered dustproof and waterproof, the tool must have a rating of IP68. 

63.

What must be placed when a technician leaves a high-voltage system repair unattended?

  • Warning signs

  • Conductive barricade

  • Cone 

  • Magnetic car topper 

Correct answer: Warning signs 

Technicians are responsible for placing warning signs when leaving a high-voltage system repair unattended. They must also maintain a defined safety zone around the work area, as per the vehicle manufacturer. 

Conductive barricades should never be used. Cones and magnetic car toppers should always mark off the xEV work area, even when the technician is present. 

64.

xEVs have a floating ground operating in what capacity with the vehicle chassis ground?

  • Not connected

  • Connected

  • Running in series

  • Running in parallel

Correct answer: Not connected

The xEV has a floating (isolated) ground. This ground is not connected to the vehicle chassis ground. 

This setup creates a built-in safety mechanism. A Diagnostic Trouble Code (DTC) is stored after two consecutive trips with the same failure. 

65.

As a Level 2 technician, when would you be expected to fight a shop fire?

  • Only when it's controllable

  • Any time fire breaks out

  • If you caused it

  • When it's caused by a high-voltage battery

Correct answer: Only when it's controllable

If the fire is small and controllable, you can fight the fire in accordance with your employer's Emergency Action Plan (EAP) Standard Operating Procedure (SOP). This controllable fire shouldn't be spreading to any other areas.

To continue fighting the fire, there must be an exit that you can back up to. 911 should also be called. 

66.

What may happen with a damaged case on test tools?

  • Internal arcing

  • Nothing

  • UV exposure infiltrates tools

  • Tools become weakened

Correct answer: Internal arcing

If the test tools have a damaged case or faded display, internal arcing is a possibility. Internal arcing can reach the user, leading to electric shock risk. These damaged tools should not be used.

A physical inspection of the case should be performed before every use. 

67.

Which of the following procedures should be used in an uncontrolled environment?

  • Lockout

  • Tagout

  • Rockout

  • Powerout

Correct answer: Lockout

Lockout is required if the environment is uncontrolled. All removed fuses, relays, and the Manual Service Disconnect (MSD) must be placed in a secure location to keep others from reinstalling the equipment and energizing the system.

Tagout is a procedure only meant for controlled environments. To use tagout, an established group policy must be in effect. 

68.

What is the lowest level technician that's qualified to isolate voltage from the EV's high-voltage system?

  • Level 2

  • Level 1

  • Level 3

  • None

Correct answer: Level 2

Level 1 technicians are not qualified to work on the high-voltage systems of the EV. To isolate voltage from the EV systems, you must be a Level 2 technician.

The Level 3 technician can also perform this work. This technician is qualified to work on EV batteries as well. 

69.

What's the best way to check a multimeter for internal breaks?

  • With the multimeter's continuity testing function

  • Through visual inspection

  • Testing current of high-voltage systems

  • Internal breaks aren't a concern

Correct answer: With the multimeter's continuity testing function

Use the digital multimeter's own continuity testing function. This process reveals if there are internal breaks that need to be dealt with before using the tool.

The test leads should always have a CAT rating that matches or exceeds that of the test tool. 

70.

Which of the following does a digital multimeter not measure?

  • Watts

  • Volts

  • Ohms

  • Amps

Correct answer: Watts

Digital multimeters don't measure watts. While there are some basic math equations that can be done to figure it out, the wattage isn't given from the digital multimeter.

A digital multimeter does measure Electromotive Force (EMF) (volts), resistance (ohms), and current (amps). 

71.

What must be in place for tagout to be used?

  • Established group policy

  • Efficient workflow

  • Secured location with a lock/key

  • At least ten employees

Correct answer: Established group policy

Tagout is a procedure used in controlled environments only. There must be an established group policy in effect.

If the environment is uncontrolled, lockout must be used instead. This procedure requires that all removed relays, fuses, and the Manual Service Disconnect (MSD) are placed in a secure location, preferably under lock and key.

72.

What is the term used to describe the state when a high-voltage electrical conductor or circuit part is disconnected and isolated from energized high-voltage parts?

  • Electrically safe work condition

  • No power state

  • Electric neutral 

  • Powered down

Correct answer: Electrically safe work condition

The electrically safe work condition is a state where high-voltage circuit parts and electrical conductors are disconnected and isolated from energized high-voltage parts. This state doesn't apply to high-voltage battery packs.

These parts must be locked or tagged in accordance with OSHA regulations. These parts must also be tested for the absence of voltage, so the technician isn't required to wear Personal Protective Equipment (PPE) around them. 

73.

What part on insulated hand tools keeps the user's hand from slipping down to the exposed metal?

  • Guard rail

  • Plastic cover

  • Rubber grip

  • Metal covering

Correct answer: Guard rail

The guard rail is required for insulated hand tools, such as cutters and pliers. It protects the user's hand from slipping onto the exposed metal portion. 

A guard rail prevents electric shock to the user. It's part of the ASTM F1505-10 guidelines. 

74.

When can insulating sleeves be used?

  • If parts will be touched with gloves alone

  • Never

  • With every job

  • At the technician's discretion

Correct answer: If parts will be touched with gloves alone

Insulating sleeves may be used if the work practices can't prevent touching energizing parts using gloves alone. These insulating sleeves must meet ASTM D1051 regulations for use.

The insulating sleeves should be inspected before and after each day's use and not worn if any contamination or damage is discovered. 

75.

What type of motor converts electrical energy from stored power into mechanical energy?

  • Traction

  • ICE

  • Diesel

  • Gas

Correct answer: Traction

The electric traction motor converts electrical energy from a stored power source to mechanical energy. This conversion occurs because of rotational force. 

The Internal Combustion Engine (ICE) uses fuel to create energy. Both the diesel and gas engine are types of ICEs. 

76.

What is the purpose of CPR?

  • Maintain blood flow

  • Promote breathing

  • Encourage consciousness

  • Reduce electrical shock damage

Correct answer: Maintain blood flow

CPR (Cardiopulmonary Resuscitation) is needed to keep the blood flow active after cardiac arrest. It may only provide partial blood flow, but that's enough to promote successful resuscitation by medical staff when they arrive. 

CPR doesn't promote breathing or encourage consciousness. It also won't stop the damage that's been done if a person has been shocked. 

77.

Test leads and probes are required to have all but which of these features?

  • Orange color

  • Shrouded connectors

  • Finger guards

  • Double insulation

Correct answer: Orange color

An orange color isn't required for test leads and probes. Orange is only required on high-voltage cables in the EV.

Test leads and probes should have shrouded connectors, finger guards, and double insulation. They are also required to have CAT ratings that equal or exceed those of the meter (CAT III 1000 V / CAT IV 600 V).

78.

Which of the following is not something that must be done before the technician can touch the conductor terminals?

  • Safety glasses are put on

  • De-energizing procedure is complete

  • Confirmation test proves there's no voltage in the conductors

  • Original Equipment Manufacturer (OEM) guidelines were followed

Correct answer: Safety glasses are put on

Safety glasses may or may not be used when working around de-energized conductor terminals, depending on the situation. Yet, de-energization must be completed before the technician may do any work.

A confirmation test is also needed to prove there's no voltage in the conductors. Additionally, all OEM (Original Equipment Manufacturer) guidelines must be followed. 

79.

What does the dashboard light with an "EV" mean?

  • Electric Vehicle (EV) mode

  • Extra Voltage

  • Exit Vehicle

  • Essential Voltage

Correct answer: Electric Vehicle (EV) mode

The dashboard symbol that features a car and the letters "EV" means that the vehicle is in EV mode. Some hybrid vehicles have an EV mode that allows them to run on battery power only. When this dashboard symbol is on, no fuel is being used. 

BEVs (Battery Electric Vehicles) don't have this warning light because EV mode is all that can be used. There's no fuel tank in BEVs. 

80.

Which of the following isn't required for electrical insulating gloves?

  • Soft inner material for comfort 

  • Stamped for MAX USE VOLT 1000V AC

  • Red-colored label with voltage range

  • Expiration date with laboratory test information

Correct answer: Soft inner material for comfort 

The lineman's gloves do not need to have a certain type of inner material to create more comfort. They must be stamped for MAX USE VOLT 1000V AC.

The electrical insulating gloves must also have a red-colored label with the voltage range specified, and have an expiration with the laboratory testing information on them.
