The Uganda DIT Workers' PAS / Occupational Test for Electricians is the national competency-based certification issued by the Directorate of Industrial Training (DIT) under the Ministry of Education and Sports. Designed to certify skills acquired informally, the assessment costs 150,000 UGX and is delivered at accredited DIT centers. It combines a written theory paper with a comprehensive practical assessment. Underpinning theory focuses on Ugandan voltage standards (240V/415V, 50Hz), safety regulations under the Electricity Regulatory Authority (ERA), standard earthing and protection, wiring methods, tool usage, and testing and commissioning of installations. This free preparation resource provides 100 detailed practice questions, detailed answer explanations, and an AI tutor to help candidates pass.

1What is the first and most critical step that a Ugandan electrician must take before commencing work on any electrical installation?
A.Wear heavy leather gloves
B.Verify that the circuit is dead using an approved voltage indicator
C.Inform the property owner that power will be turned off
D.Turn off the nearest individual branch circuit breaker
Explanation: Safe isolation is the absolute first step. Before touching any conductors, the electrician must isolate the supply and verify that the circuit is dead using an approved voltage indicator. Relying on switch positions or simple neon test pens can be fatal.
2Which type of personal protective equipment (PPE) is essential for protecting an electrician from electric shock while working on site?
A.Steel-toed boots with metal eyelets
B.Insulated safety boots with non-conductive rubber soles
C.Standard canvas running shoes
D.Standard leather gloves without dielectric rating
Explanation: Insulated safety boots with non-conductive rubber soles provide electrical isolation from the ground, preventing the body from completing a path for fault current. Metal eyelets or canvas shoes can conduct electricity and increase shock hazard.
3If you find a colleague suffering from an active electric shock and still in contact with a live wire, what is your first course of action?
A.Pull them away immediately using your bare hands
B.Throw water on them to extinguish any potential fire
C.Immediately switch off the main power supply or isolate the source
D.Call an ambulance before taking any other action
Explanation: The immediate priority is to break the contact between the victim and the electrical source by safely turning off the power. Attempting to pull them off with bare hands will cause you to become a victim as well. If the source cannot be switched off quickly, use a non-conducting object (like dry wood or plastic) to push the wire away.
4Which type of fire extinguisher is safe to use on an active electrical fire in a domestic installation?
A.Water extinguisher
B.Carbon Dioxide (CO2) or dry chemical powder extinguisher
C.Wet chemical extinguisher
D.Foam extinguisher
Explanation: CO2 and dry chemical powder extinguishers are non-conductive and safely extinguish electrical fires without risking shock to the operator. Water, foam, and wet chemical extinguishers contain conductive water-based solutions and should never be used on live electrical equipment.
5Which of the following conditions on an electrical hand tool presents an immediate safety hazard that requires the tool to be taken out of service?
A.A slightly scratched plastic handle
B.Frayed or cracked insulation on the power supply cord
C.Faded manufacturer label on the side
D.A small speck of rust on the metal casing of the motor housing
Explanation: Frayed or cracked insulation on power cords exposes live wires, creating an immediate danger of shock, electrocution, or short circuit. Such tools must be tagged and removed from service immediately for repair or replacement.
6What is the correct first-aid response for treating a minor electrical burn on a worker's forearm?
A.Apply cooking fat or petroleum jelly to the burn area
B.Flush the burn under cool, clean running water for at least 10 minutes
C.Wrap it tightly with a dry adhesive bandage immediately
D.Prick any blisters that form to relieve the pressure
Explanation: Cooling the burn with clean running water for at least 10 to 20 minutes limits tissue damage and relieves pain. Applying fats or oils traps heat, worsening the burn and increasing infection risk. Blisters should never be broken as they protect the underlying skin.
7When working on a domestic distribution board, what is the purpose of the Lockout/Tagout (LOTO) procedure?
A.To prevent dust from entering the circuit breakers
B.To ensure the installation remains physically secure against theft
C.To prevent accidental re-energization of the circuit while work is in progress
D.To document the electricity consumption during maintenance
Explanation: Lockout/Tagout ensures that the circuit breaker or main switch isolating the work area is physically locked in the 'OFF' position and tagged with a warning label. This prevents other workers or occupants from accidentally switching the power back on while the electrician is working.
8What is the standard trip current threshold for a residual current device (RCD) installed for personal shock protection in domestic plug socket circuits?
A.100 mA
B.30 mA
C.10 mA
D.300 mA
Explanation: A threshold of 30 mA is the standard for RCDs intended to protect human life. At currents above 30 mA, ventricular fibrillation (heart arrest) can occur rapidly. An RCD rated at 30 mA will disconnect the supply within milliseconds of detecting a leakage to earth.
9What primary hazard should an electrician prepare for when working in a cramped attic or roof void in Uganda?
A.Lack of oxygen due to high altitude
B.Extreme heat, dust, and structural instability of ceiling joists
C.High-voltage electrostatic shock from roof tiles
D.Direct exposure to toxic industrial chemical fumes
Explanation: Attic and roof spaces in tropical climates like Uganda accumulate extreme heat, contain irritating dust/fiberglass fibers, and require stepping only on structural ceiling joists (beams) to prevent falling through the gypsum or soft ceiling board below.
10When leaning a straight ladder against a wall for electrical installation work, what is the recommended slope ratio for safety?
A.1:1 ratio (45 degrees)
B.4:1 ratio (approx. 75 degrees), where for every 4 units of height, the base is 1 unit out
C.10:1 ratio (approx. 85 degrees)
D.2:1 ratio (approx. 60 degrees)
Explanation: The 4:1 ratio (the '4-to-1 rule') ensures the ladder is stable, preventing it from slipping out at the bottom or tipping backward. For instance, if the ladder meets the wall 4 meters up, the base must be 1 meter away from the wall. Ladder rails should also be non-conductive (fiberglass or dry timber).
