1Which level of electric current flowing through the human body is generally considered the threshold where ventricular fibrillation (fatal heart disruption) can occur?
A.1 mA to 5 mA
B.5 mA to 10 mA
C.50 mA to 100 mA
D.10 A to 15 A
Explanation: A current between 50 mA and 100 mA (0.05 to 0.1 amperes) flowing through the body is sufficient to cause ventricular fibrillation, which stops the heart's pumping action and can be rapidly fatal without immediate CPR and defibrillation. Lower currents cause mild sensation or muscle contraction, while currents above several amperes cause severe burns but may not cause fibrillation.
2What is the very first action you should take when you find a person receiving an electric shock in a workshop?
A.Pull the victim away from the live conductor with your bare hands
B.Safely isolate the electrical power supply or switch off the main circuit breaker
C.Apply cold water to the victim's body to cool the burn injuries
D.Immediately begin cardiopulmonary resuscitation (CPR)
Explanation: The first and most critical action is to safely isolate the power supply to stop the current flow through the victim. Touching the victim directly while they are still in contact with the live source will make you part of the electrical circuit, causing you to receive a shock too. Only after the current is safely stopped should you approach to administer first aid or CPR.
3In electrical safety and lock-out tag-out (LOTO) procedures, what does the term 'double isolation' refer to?
A.Disconnecting both the phase (live) and neutral conductors from the supply source
B.Installing two separate fuses in series on the phase conductor
C.Using two padlocks of different colors on a single circuit breaker switch
D.Wrapping two layers of PVC insulation tape around a copper joint
Explanation: Double isolation means isolating both the phase (live) and neutral conductors of a circuit from the source of supply. This ensures complete electrical separation, preventing any potential feedback or rise in neutral voltage from energizing the isolated work area. It is a critical practice during maintenance of single-phase systems.
4Which type of fire extinguisher is specifically designated and safe for extinguishing electrical fires?
A.Class A Water fire extinguisher
B.Class B Foam fire extinguisher
C.Class C Carbon Dioxide (CO2) or Dry Powder fire extinguisher
D.Wet Chemical fire extinguisher
Explanation: Carbon Dioxide (CO2) and Dry Powder fire extinguishers are non-conductive and safe for Class C (electrical) fires. They extinguish the fire by displacing oxygen or interrupting the chemical reaction without conducting electricity back to the operator or damaging the electrical equipment with liquid residues.
5What is the primary safety purpose of wearing arc-rated personal protective equipment (PPE) when working on live switchboards?
A.To protect the technician from physical impact from heavy falling tools
B.To shield the technician from the intense thermal energy and blast pressure of an arc flash
C.To prevent minor cuts and scratches when routing cables
D.To increase the technician's physical strength when operating switches
Explanation: Arc-rated PPE (such as arc flash suits and face shields) is designed to protect electrical workers from the extreme thermal energy (heat) and pressure waves generated during an arc flash. An arc flash can reach temperatures hotter than the sun, and standard clothing can ignite, causing fatal burns.
6When administering CPR to an adult electrical shock victim, what is the correct depth and rate of chest compressions?
A.1 to 2 cm depth at a rate of 60 compressions per minute
B.5 to 6 cm depth at a rate of 100 to 120 compressions per minute
C.8 to 10 cm depth at a rate of 150 compressions per minute
D.3 to 4 cm depth at a rate of 80 compressions per minute
Explanation: International first aid guidelines specify that adult CPR chest compressions should be 5 to 6 cm deep (approximately 2 inches) and delivered at a rate of 100 to 120 compressions per minute. This rate and depth optimize blood circulation to vital organs while the heart is stopped.
7What is the maximum nominal AC voltage limit considered as 'Extra-Low Voltage' (ELV) in dry conditions, below which the risk of fatal electric shock is minimal?
A.12 V AC
B.50 V AC
C.110 V AC
D.240 V AC
Explanation: Under standard electrical regulations, Extra-Low Voltage (ELV) is defined as not exceeding 50 V AC (or 120 V ripple-free DC). In dry conditions, the electrical resistance of human skin is high enough that contact with voltages below 50 V AC is highly unlikely to drive enough current to cause death or severe shock.
8What is the correct immediate first aid treatment for a technician who has sustained minor electrical burns on their forearm?
A.Apply grease, butter, or cooking oil to the burn area
B.Cool the burn area with clean, running water for at least 10 to 20 minutes
C.Break any blisters that form to release the trapped fluid
D.Wrap the burn tightly with a dry wool blanket
Explanation: The correct immediate treatment for minor burns is to cool the affected skin under clean, cool running water for 10 to 20 minutes. This stops the burning process, reduces swelling, and relieves pain. Oils or grease must never be applied as they trap heat and increase the risk of infection.
9What is the main purpose of a 'Permit-to-Work' (PTW) system in industrial electrical installations?
A.To allow unqualified personnel to perform electrical tasks
B.To ensure that electrical work is formally authorized, hazards are assessed, and safety controls are implemented
C.To prove to customers that the materials used are cheap
D.To speed up the completion of installation works by bypassing testing
Explanation: A Permit-to-Work system is a formal, written safety control system used to manage high-risk activities. It ensures that only authorized, competent personnel carry out the work, all hazards are identified, isolation points are verified, and safety precautions are fully in place before work starts.
10What is the safest practice when using a ladder to work near overhead electrical power service lines?
A.Use an aluminum ladder because it is lightweight
B.Use a dry timber or fiberglass ladder and maintain a safe clearance distance
C.Wrap the top of an aluminum ladder with plastic bags
D.Rest the ladder directly against the power line to ensure stability
Explanation: When working near electrical lines, a non-conductive ladder made of fiberglass or dry timber must be used. Additionally, a safe clearance distance must be maintained at all times. Aluminum is an excellent conductor of electricity and should never be used near exposed electrical lines.

Frequently Asked Questions

What is the CTVET Certificate II in Electrical Engineering Technology?

It is a national vocational qualification awarded by the Commission for Technical and Vocational Education and Training (CTVET) in Ghana. It confirms that a technician possesses the fundamental theoretical and practical competencies required to carry out safe electrical installations and repairs.

What regulations govern electrical wiring in Ghana?

Electrical installations in Ghana are legally governed by the Electrical Wiring Regulations, 2011 (Legislative Instrument 2008, or L.I. 2008). It is enforced by the Energy Commission of Ghana and mandates that all wiring must be done by a Certified Electrical Wiring Professional (CEWP).

What are the requirements to connect an installation to the grid in Ghana?

Under L.I. 2008, once an electrical installation is completed, the Certified Electrical Wiring Professional (CEWP) must test the installation and fill out the completion certificate (Form A). Companies like ECG or NEDCo will not provide a meter or connect power without this Form A certificate.

What is the passing score for the CTVET Certificate II Electrical exam?

The written and practical examinations typically require a minimum score of 50% to be deemed competent. Candidates must demonstrate proficiency in both theoretical knowledge (trade theory) and hands-on skills (practical assessment).

Can I progress to a tertiary institution after this course?

Yes. Holding a CTVET Certificate II in Electrical Engineering Technology qualifies you to progress to a Higher National Diploma (HND) or a Bachelor of Technology (B.Tech) program in Electrical/Electronic Engineering at any technical university in Ghana.
