Israel Electrician Licensing Exam study guide
Israel Electrician Licensing Exam · Work through your exam, one topic at a time.
The Israel Electrician Licensing Exam is the assessment through which candidates demonstrate the knowledge required to hold an electrician's licence in Israel. It is intended for practising electricians and apprentices who need formal recognition of their competence, as well as for immigrants with electrical training from abroad who seek to work in the Israeli trade. The Israel Electrician Licensing Exam study guide has 8 sections and about 2,661 words.
01Electrical Theory and Fundamentals
Electrical Theory and Fundamentals underpins every calculation you will make on site and in the exam: Ohm's law, series and parallel networks, AC quantities, and the power relationships used on 230/400 V, 50 Hz systems. Ohm's law V = I·R; power P = V·I = I²R = V²/R.
307 words, about 2 min02Electrical Installation Design and Calculations
Installation design and calculations test whether you can size a circuit from the load through to the protective device and prove it is safe: design current, device rating, cable capacity, voltage drop and short-circuit withstand. Assess the load and apply demand/diversity factors to obtain the design current Ib.
329 words, about 2 min03Wiring Systems, Cables, and Protection Devices
Wiring systems, cables and protection devices cover selection and erection: which wiring method suits the building, which cable construction suits the environment, and which device protects the circuit without nuisance tripping. Conduit embedded in concrete or plaster, surface conduit, trunking, cable tray and ladder, and direct burial with armoured or sheathed cable.
325 words, about 2 min04Earthing, Bonding, and Protection Against Electric Shock
Earthing, bonding and protection against electric shock is where the most marks are lost, because the answer depends on the declared earthing system (TN-S, TN-C-S, TT, IT) and on whether faults are cleared by overcurrent devices or by residual current devices. Exposed conductive parts are connected to the protective conductor (PE); extraneous conductive parts are connected by main protective bonding to the main earthing terminal.
333 words, about 2 min05Safety at Work, Electrical Hazards, and First Aid
Safety at work, electrical hazards and first aid tests judgement as much as memory: recognising the hazard, isolating correctly, and acting properly in the first minutes after a shock. Isolate, lock off and tag.
340 words, about 2 min06Israeli Electrical Code and Standards (SI 100, SI 900, etc.)
The Israeli code domain tests whether you can apply the national framework - the Electricity Law and its regulations, SI 100, SI 900 and the SI 32 plug standard - rather than quoting IEC text directly, because the Israeli documents adopt IEC 60364 with national amendments. The Electricity Law, 1954, and the Electricity Regulations made under it define who may carry out electrical work, the licensing grades and the scope of each grade.
342 words, about 2 min07Inspection, Testing, and Fault Diagnosis
Inspection, testing and fault diagnosis covers the sequence of verification, the instruments used, and how to interpret a reading that does not match the design. Visual inspection before any instrument is used: identification, damage, IP rating, fire sealing, barriers, correct device ratings, documentation.
323 words, about 2 min08Electrical Machines, Transformers, and Motors
Electrical machines, transformers and motors covers the magnetic and mechanical side of the trade: how a transformer or motor behaves, how it is started, and how it is protected. EMF equation E = 4.44·f·N·Φ; turns ratio a = N1/N2 = U1/U2, so an 11 kV/400 V transformer has a ≈ 27.5.
