SSC Junior Engineer (JE): Electrical

Evidence status: 🟢 official. Every number below is from the SSC Junior Engineer Examination, 2026 notice (F. No. HQ-C-3019/1/2026-C-3), fetched from ssc.gov.in on 2026-09-29.

SSC JE recruits Junior Engineers (Group B, non-gazetted) for central departments (including CPWD, BRO, CWPRS, and CWC). Its technical syllabus covers diploma-level core Electrical Engineering, which a GATE or ESE aspirant covers in depth, plus non-technical reasoning and general awareness in Paper I, and SSC-specific applied subjects (estimation, costing, and utilisation).

Exam pattern

The examination consists of two computer-based objective stages.

Paper I: computer-based, 2 hours, 200 questions, 200 marks, −0.25 negative marking per wrong answer. Paper I is qualifying in nature; normalized scores are used solely to shortlist candidates for Paper II and are not counted towards the final merit list.

Section Questions Marks
General Intelligence and Reasoning 50 50
General Awareness 50 50
Part-B General Engineering (Electrical) 100 100
Total 200 200

Paper II: computer-based objective, 2 hours, 100 questions, 300 marks (3 marks per question), −1.00 negative marking per wrong answer. It covers exclusively Part-B General Engineering (Electrical). The final merit list is determined solely on normalized marks in Paper II.

Section Questions Marks
Part-B General Engineering (Electrical) 100 300

Exam tools on console: A virtual scientific calculator and relevant engineering tables are integrated directly into the computer console interface during CBT. Physical calculators and paper tables are strictly prohibited.

Syllabus

The official syllabus covers general non-technical abilities and diploma-level electrical engineering subjects.

Non-technical sections (Paper I)

  • General Intelligence and Reasoning: verbal and non-verbal reasoning, analogies, similarities, differences, space visualization, problem solving, analysis, judgement, visual memory, discrimination, observation, relationship concepts, arithmetical reasoning, and number series.
  • General Awareness: current events, scientific aspects of everyday observation, and general knowledge of India and neighbouring countries (History, Culture, Geography, Economic Scene, General Polity, and Scientific Research).

General Engineering (Electrical) (Paper I & Paper II)

Covered under the shared Electrical Engineering core module. The official curriculum specifies:

  1. Fundamentals of Electrical Engineering: circuit elements (resistors, capacitors, inductors, batteries) and factors affecting their values; concepts of voltage, current, power, energy, flux, and standard units; network solution methods (KCL, KVL, nodal and mesh analysis); network theorems (Thevenin's, Norton's, Superposition, and Maximum Power Transfer theorems).
  2. Magnetic Circuits: concepts of flux, reluctance, self and mutual inductance, magnetomotive force (MMF), and magnetic circuit calculations.
  3. A.C. Fundamentals: RMS and average values of alternating waveforms; series and parallel AC circuits; resonance; balanced three-phase circuits; star-delta transformation; complex power and power factor.
  4. Measurement and Measuring Instruments: measurement of voltage, current, power, and power factor; classification of instruments and types of errors; PMMC (galvanometer, ammeter, voltmeter); moving iron; dynamometer wattmeter; resistance bridges (Wheatstone bridge, Kelvin's double bridge); Megger; induction energy meter; CT, PT and their uses.
  5. Electrical Machines: Single-phase and Three-phase Transformers; DC Machines (types, characteristics, losses, efficiency, applications); AC Machines (Induction Motors: starting, speed control, braking, torque-speed characteristics); Special Electric Machines and Synchronous Generators (fractional motors, servomotors, armature reaction, parallel operation, synchronization).
  6. Generation, Transmission and Distribution: power stations, load/demand/diversity factors; power factor improvement; transmission/distribution lines, parameters, Corona and Ferranti effects; circuit breakers; protection of generators and transformers; coaxial cables.
  7. Estimation & Costing: estimation of lighting schemes; electric installation of machines; IE Rules; earthing practices.
  8. Utilization of Electrical Energy: illumination, electric heating, welding, electroplating, traction, and drives.
  9. Basic Electronics: P-N Junction Diodes, rectifiers, wave-shapers, clipping, clamping; BJT and FET transistors (characteristics, amplifiers, oscillators).
  10. Power Electronics: static V-I characteristics of Thyristor; firing/gating circuits; DC-DC conversion (Buck, Boost, Buck-Boost); single-phase rectifiers.
