Sample Maharashtra SSC Electrical & Hardware Installation Tech Pre-Voc/NSQF Practice Questions
Try these sample questions to test your Maharashtra SSC Electrical & Hardware Installation Tech Pre-Voc/NSQF exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.
1Before working on a live electrical installation, the first safety action is to:
A.Isolate the supply, lock/tag out if required, and verify absence of voltage
B.Touch conductors with a wet finger to check voltage
C.Remove only the neutral and leave the phase connected
D.Wear cotton gloves without insulating rating
Explanation: Safe work practice requires isolation of the circuit, lockout/tagout where site rules require it, and a verified dead test before contact. Guessing by touch or partial disconnection leaves shock and arc risk.
2Which personal protective equipment (PPE) is most appropriate when using a power drill overhead on a construction site?
A.Safety helmet, safety glasses, and safety shoes
B.Loose scarf and open sandals only
C.Metal jewellery on both hands for grip
D.No PPE if the work is brief
Explanation: Overhead drilling risks falling debris and eye injury. A hard hat, eye protection, and safety footwear are baseline PPE. Loose clothing, jewellery, and skipping PPE increase entanglement and injury risk.
3A Class B fire involving flammable liquids near electrical equipment should generally be fought with:
A.A water jet directed into the live panel
B.An extinguisher rated for flammable liquids and safe for the electrical risk present
C.Only wet sand thrown by hand with no plan
D.A garden hose from the nearest tap
Explanation: Flammable-liquid fires need the correct extinguisher class; if electrical equipment is involved, the agent must also be non-conductive or the supply must be isolated first. Water jets and hoses can spread fuel and conduct electricity.
4When climbing a portable ladder to reach a ceiling rose, safe practice includes:
A.Standing on the top cap of a step ladder for extra height
B.Placing the ladder on a firm, level base and maintaining three points of contact
C.Propping the ladder on stacked boxes
D.Leaning far sideways beyond the ladder rails
Explanation: Ladders must sit on a stable base. Three points of contact reduce falls. Standing on the top cap, using unstable props, or overreaching are common causes of site accidents.
5Insulated hand tools for electrical work are preferred because they:
A.Make tools heavier so they never slip
B.Provide a dielectric barrier that reduces shock risk if accidental contact occurs
C.Eliminate the need for circuit isolation
D.Allow live busbars to be used as handholds
Explanation: Insulated tools help protect against accidental contact with live parts, but they do not replace isolation and dead testing. Work on known live systems needs special procedures and training.
6If a co-worker receives an electric shock and remains in contact with a live conductor, the first priority for a rescuer is to:
A.Pull the victim with bare hands immediately
B.Disconnect or isolate the supply if it can be done safely, then follow first-aid steps
C.Pour water on the victim while they are still energised
D.Photograph the scene before any action
Explanation: Rescuers must not become second victims. Safe isolation (or moving the victim with a non-conductive means only if isolation is impossible and training allows) comes first, then first aid and emergency services.
7Housekeeping on an electrical installation site mainly reduces risk by:
A.Keeping walkways clear of cable offcuts, tools, and packaging
B.Hiding scrap wire under floorboards permanently
C.Leaving open junction boxes as trip markers
D.Storing flammable solvents next to distribution boards
Explanation: Clear access routes, controlled waste, and orderly tool storage reduce trips, cuts, and fire hazards. Concealing scrap or mixing chemicals with electrical gear creates hidden dangers.
8A residual current device (RCD / ELCB family protective device) primarily protects against:
A.Slow voltage sag from the utility only
B.Earth leakage currents that could cause shock or fire
C.Slight colour fading of cable insulation
D.Mechanical overload of a ladder
Explanation: RCDs monitor imbalance between live and neutral (or phase currents) and trip on leakage to earth, reducing shock and some fire risks. They do not replace overcurrent protection for short circuits and overload in all designs.
9Which practice is unsafe when using a portable electric drill on site?
A.Inspecting the cable and plug for damage before use
B.Using a damaged or frayed flexible cord because the job is nearly finished
C.Selecting a drill bit suitable for the material
D.Securing loose clothing and hair before starting
Explanation: Damaged flexible cords can expose live conductors and cause shock or fire. Pre-use inspection, correct bits, and control of loose clothing are safe practices.
10Warning signs and barricades around an open floor trench with temporary cables are used mainly to:
A.Decorate the site for clients
B.Alert workers and visitors to trip and electrical hazards and restrict access
C.Increase cable resistance intentionally
D.Replace the need for earthing
Explanation: Temporary barriers and signs communicate hazards and control access while work is incomplete. They do not change electrical parameters or substitute for protective earthing.
