Iran Nezam Electrical Supervision Exam study plan

Iran Nezam Electrical Supervision Exam · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Electrical Building Systems Design (lighting, power distribution, receptacle and circuit layouts) & Codes and Standards (Iranian national building code, electrical installations standard, and referenced regulations)

Map each clause of the Iranian national building code electrical chapter and the electrical installations standard to the eight exam domains, producing a one-page cross-reference table.
Solve 30 lighting design problems covering lumen method, room index, utilization factor, and maintained illuminance targets for residential, office, and industrial spaces.
Draw a complete receptacle and circuit layout for a three-bedroom apartment, assigning each outlet to a circuit and labeling protection ratings.
List the ten code clauses you personally find most ambiguous and write down the exact article number and wording for each.

A 10-page design notebook containing the code cross-reference table plus the fully annotated apartment lighting and receptacle layout.

Week 2

Compute branch-circuit and feeder loads for a 12-unit residential building using demand factors from the standard, showing every step.
Build a panel schedule for a main distribution board with 24 outgoing circuits, including phase balancing across three phases.
Calculate voltage drop for the three longest feeders using resistance and reactance values, and verify results against the permitted percentage limits.
Identify and correct five deliberately unbalanced or overloaded panel schedules given as text descriptions.

A finished main panel schedule with load calculation sheet and voltage-drop verification for three feeders.

Week 3

Size conductors for 20 scenarios combining ambient temperature correction and conduit fill derating, documenting each table reference.
Select conduit and trunking sizes for mixed power and low-voltage runs, respecting separation requirements.
Design a complete earthing and bonding scheme for a commercial building, including main earthing terminal, protective conductors, and equipotential bonding of metallic services.
Specify residual current device types and sensitivities for socket outlets, bathrooms, and outdoor circuits, and justify each choice.
Compare overcurrent protective device coordination for a two-level distribution system and flag any lack of selectivity.

A cable and protection schedule for a four-floor commercial building with derating calculations and an earthing single-line diagram.

Week 4

Summarize the supervision duties of the licensed engineer across design review, construction inspection, and final acceptance, citing the relevant regulatory articles.
Draft a checklist of 25 inspection points an engineer must verify before energizing a new installation.
Explain in writing the legal consequences of signing off on non-compliant work, including liability and disciplinary exposure.
Complete 40 mixed multiple-choice questions from domains 1 through 4 and log every wrong answer with its root cause.

A supervision inspection checklist with 25 items plus a written liability summary, and an error log covering 40 practice questions.

Week 5

Classify ten given spaces into hazardous area zones and select wiring methods, enclosures, and ingress protection ratings for each.
Design fire-rated cable routing and penetration sealing for a building with two fire compartments.
Specify fire detection and alarm cabling, including circuit integrity requirements and separation from power circuits.
Produce a safety audit of a described installation listing shock, thermal, and arc-flash hazards with a mitigation for each.

A hazardous-area and fire-protection specification sheet covering ten classified spaces and two fire compartments.

Week 6

Design emergency lighting for a five-storey building, calculating illuminance, escape route coverage, and battery autonomy.
Lay out fire alarm detection zones, manual call points, and sounders to meet coverage rules for a given floor plan described in text.
Specify the dedicated power supply, protection, and earthing for elevator machine rooms and lift shafts.
Plan structured cabling and IT/communication pathways with separation from power and proper bonding of screens and racks.
Describe the interconnection requirements for a rooftop photovoltaic system, including isolation, protection, and metering.

A special-systems package containing emergency lighting calculations, fire alarm device layout, and a photovoltaic interconnection schematic.

Week 7

Redo a full design from scratch under timed conditions: lighting, power, panel schedule, and voltage drop for a mid-size building.
Resolve 60 mixed practice questions weighted toward the heaviest domains and review every miss against the code text.
Re-verify your design notebook against the standard and correct at least five errors you find.
Write a one-page summary of the ten code numbers and limits you are most likely to forget, and memorize them.

A complete timed design solution plus a personal sheet of the ten most forgettable code limits, both reviewed and corrected.

Week 8

Complete two full mock exams under time pressure and score each against the domain weighting.
Review every missed question from the mock exams and rewrite the underlying rule in your own words.
Rehearse explaining three supervision decisions aloud, as you would in a professional or oral review.
Finalize a one-page pre-exam reference card limited to formulas, demand factors, and voltage-drop limits.

Two scored mock exams with a corrected error log and a single-page pre-exam reference card.

Week 2: You can produce a balanced panel schedule with verified voltage drop for a multi-unit building without consulting worked examples.

Week 4: You score at least 70 percent on 40 mixed questions from domains 1 to 4 and can list 25 pre-energization inspection points from memory.

Week 6: You can design emergency lighting, fire alarm coverage, and a photovoltaic interconnection for a described building in one sitting.

Week 8: You score at least 75 percent on both full mock exams with no domain below 60 percent.
