Maharashtra SSC Electrical & Hardware Installation Tech Pre-Voc/NSQF study plan

List the five common domestic protection devices (MCB, RCCB/ELCB, fuse, earthing, isolator) and state in one line what fault each one clears

Draw from memory a single-phase domestic distribution path from meter to a 6 A lighting circuit and a 16 A power circuit, labelling MCB ratings

Solve 15 Ohm's law problems (V = IR, I = V/R, R = V/I) with values drawn from real appliance nameplates, showing units at every step

Demonstrate the safe isolation sequence - isolate, lock/tag, prove tester on a known live source, test dead, re-prove tester - and record it as a numbered checklist

Explain in writing why an RCCB rated 30 mA protects people while an MCB protects cables

Calculate power, energy and current for 10 appliances using P = VI and energy = power × time in kWh

Size a fuse or MCB for a given load by applying a 1.25–1.5 safety factor and justify the choice

Compute voltage drop for a 20 m two-core run at a stated current and compare it against a 3% limit

Identify the live, neutral and earth terminals on a socket, a switch and a ceiling rose, and state the correct core colour for each

Explain the difference between earthing and neutral in at least five sentences with a simple sketch

Demonstrate and describe first aid for electric shock: safe isolation of supply, calling for help, CPR compression rate and depth, and recovery position

Match each of the four shock severity factors (current magnitude, path, duration, frequency) to a practical precaution

Select the correct tool for stripping, cutting, crimping and screwing, and name one misuse of each

Demonstrate use of a digital multimeter for voltage, continuity and resistance, including range selection and zeroing

Read a vernier caliper and a micrometer to 0.02 mm and 0.01 mm respectively on three sample readings

State the PPE required for live-adjacent work and the conditions under which live work is never permitted

Classify 15 given materials as conductor, semiconductor or insulator and state one domestic use for each

Compare PVC, XLPE and rubber insulation on temperature rating and where each is used

Identify by description the standard fasteners - wood screw, machine screw, self-tapping screw, anchor bolt, rawl plug, wall plug - and match each to a wall or fixture type

Select the correct drill bit size and plug for a given screw and wall substrate (brick, concrete, plasterboard, wood)

Explain how to find a safe fixing point without damaging concealed wiring, and state the minimum depth and pull-out check for a wall plug

Wire a one-way switch controlling a lamp and a three-pin socket on a practice board, then test continuity, polarity and insulation resistance

Wire and test a two-way switch circuit and explain the strapper connections

Describe the internal parts and one common failure of a ceiling fan, an electric iron and a water heater

Write a five-step fault-finding routine for a dead socket and apply it to a simulated fault

State the maintenance interval and check for each of the three appliances above

Mount a distribution board, a switch box and a luminaire on a practice surface using the correct fasteners and check alignment and tightness

Install and torque-check three types of fixture fixing (plug-and-screw, anchor, bracket) and record the pull test result

Carry out a preventive maintenance routine on a fan and a heater, listing every check performed

Use a clamp meter and a megger correctly, stating the safety precaution for each

Explain how to inspect and replace a worn plug top, flex and terminal connection safely

Recognise and draw the standard symbols for switch, socket, lamp, fan, MCB, fuse, earth and distribution board

Convert a written circuit description into a neat wiring diagram and a single-line diagram

Trace a given wiring diagram and list the components and connections in order from supply to load

Draw a simple layout plan of a one-room installation showing points, runs and the board position

Check a diagram for three deliberate errors (wrong polarity, missing earth, overloaded circuit) and correct them

Write a short CV and a covering note for an electrical/hardware technician role, listing the practical skills gained in weeks 1–7

Prepare and deliver a two-minute spoken explanation of electrical safety to a layperson, covering shock, earthing and RCCB

Draft a simple quotation for a small domestic wiring job including material, labour and a safety note

Complete a timed 40-question mixed mock test across all nine domains and review every wrong answer

List three self-employment options in electrical hardware work and the licence or registration each needs
