1Under the Israeli Electricity Regulations (Earthing and Protection against Electrocution), what is the foundational rule governing the PEN conductor at the service entrance in a TN-C-S (איפוס) system?
A.The PEN conductor may be reconnected to the neutral conductor at any sub-distribution board within the facility.
B.The neutral conductor must be connected to an isolated earth electrode kept separate from the building foundation earthing system.
C.The protective conductor (PE) must be switched by the main multi-pole incoming circuit breaker alongside the phase conductors.
D.The incoming PEN conductor is separated into distinct PE and N conductors at the main distribution board, and they must never be reconnected downstream.
Explanation: In a TN-C-S (איפוס) system the incoming combined protective-neutral conductor (PEN) is connected to the main equipotential bonding bar (פה"פ) and separated there into a protective earth conductor (PE) and a neutral conductor (N). The Electricity Regulations prohibit reconnecting PE and N anywhere downstream of that point, because doing so would send normal neutral return current through protective conductors, metal raceways and equipment frames.
2What is the maximum permissible continuous prospective touch voltage (מתח מגע מרבי מותר, UL) in standard low-voltage electrical installations under normal environmental conditions in Israel?
A.50 V AC
B.24 V AC
C.12 V AC
D.110 V AC
Explanation: Under the Electricity Regulations (Earthing and Protection against Electrocution at voltages up to 1000 V), the conventional touch-voltage limit (מתח מגע) in ordinary dry premises is 50 V AC. Protective measures and disconnection times are all derived from keeping a faulted enclosure below this value. Reduced limits apply only in specified higher-risk locations.
3Regulation 8 of the Electricity Regulations (Foundation Earthing), 5741-1981 lists the metallic services inside a building that must each be connected to the main equipotential bonding bar (פה"פ) by a separate bonding conductor. Which set matches that statutory list?
A.Interior conduit fixing screws, luminaire trim rings and the earth pins of branch-circuit socket outlets.
B.Only the incoming neutral conductor supplied by the distribution utility transformer.
C.Foundation earthing electrode, main cold-water entry, main sewage piping, central heating and hot-water piping, main gas entry, compressed-air piping, elevator guide rails and central air-conditioning metal ducts.
D.Metal office furniture, air-supply grilles and non-structural aluminium window casings.
Explanation: Regulation 8 enumerates the metallic services that must each be bonded to the פה"פ by its own connecting conductor: the foundation earthing electrode, the main cold-water entry, main sewage piping, central heating and hot-water piping, the main gas entry, compressed-air piping, the protective and system earthing of any generator, transformer or converter, elevator guide rails, central air-conditioning metal ducts, telephone installation earthing, and any other metallic service in the building. Lightning-protection conductors are handled separately — Regulation 3(ח) routes them to the external outlets of the foundation bridging ring.
4Under Regulation 9 of the Electricity Regulations (Foundation Earthing), what is the minimum cross-sectional area of a connecting conductor (מוליך חיבור) running from an extraneous metallic service to the main equipotential bonding bar (פה"פ)?
A.2.5 mm²
B.10 mm²
C.6 mm²
D.35 mm²
Explanation: Regulation 9 states plainly that a connecting conductor shall have a cross-section of at least 10 mm², and that it may be bare; if it is insulated, the insulation must be green/yellow as required for a protective conductor. The rule is a fixed statutory minimum — it is not scaled from the phase conductor size.
5Regulation 3(א) of the Electricity Regulations (Foundation Earthing) defines what a foundation earthing electrode (אלקטרודת הארקת יסוד) may be made of. Which specification satisfies it?
A.A steel strip at least 3 mm thick with a cross-section of at least 100 mm².
B.A steel strip at least 3.5 mm thick with a cross-section of at least 90 mm².
C.A round steel bar at least 8 mm in diameter.
D.A steel strip at least 3.5 mm thick with a cross-section of at least 100 mm², or a round steel bar at least 10 mm in diameter.
Explanation: Regulation 3(א) permits three forms of electrode: a steel strip at least 3.5 mm thick whose cross-section is at least 100 mm²; a round steel bar of at least 10 mm diameter; or the building's own reinforcing steel of at least 10 mm diameter, provided it is embedded in the concrete foundation in the ground. Both the thickness and the cross-section conditions must be met together — a common commercial strip meeting them is 30 mm x 3.5 mm (105 mm²).
6In a 230 V single-phase circuit protected by a 16 A Type C miniature circuit breaker (MCB) in a TN system, what is the maximum permissible total fault loop impedance (עכבת לולאת תקלה, Zs) that still guarantees instantaneous magnetic tripping?
A.1.44 Ω
B.2.88 Ω
C.0.72 Ω
D.4.60 Ω
Explanation: A Type C breaker is guaranteed to trip magnetically only once the current reaches the top of its band, Ia = 10 x In = 160 A. With a nominal phase-to-earth voltage U0 = 230 V, the loop impedance must satisfy Zs <= U0 / Ia = 230 V / 160 A = 1.4375 Ω, which rounds to 1.44 Ω. Designing to the top of the band is what makes the disconnection time deterministic.
7In an installation protected under the TT earthing system with a touch voltage limit UL = 50 V, what is the maximum permissible earth electrode resistance (RA) when fault protection is provided by a 300 mA residual current device?
A.50.0 Ω
B.300.0 Ω
C.166.7 Ω
D.16.7 Ω
Explanation: In a TT system, protection by an RCD requires RA x IΔn <= UL. Rearranging gives RA <= UL / IΔn = 50 V / 0.3 A = 166.67 Ω. If the electrode resistance exceeds this value, a residual current just below the tripping threshold would already hold the enclosure above the 50 V touch limit indefinitely.
8Which prerequisite must be verified before an existing installation may be converted to TN-C-S (איפוס)?
A.The building must have an on-site three-phase standby generator available.
B.The building must possess an effective foundation earthing electrode and main equipotential bonding with verified electrical continuity.
C.Every socket outlet in the building must first be replaced with a residual-current-protected unit rated at 10 mA.
D.The incoming utility supply must be taken from an overhead network rather than an underground cable.
Explanation: איפוס may be applied only where the building has an effective local earth — normally a foundation earthing electrode — together with complete main equipotential bonding of all incoming metallic services. That local earth is what limits the touch voltage if the supply PEN conductor is ever interrupted; without it, a broken PEN would put the full phase voltage on every bonded enclosure.
9Why is it prohibited to create a second איפוס (neutral-to-earth bond) at a sub-distribution board inside a building whose main board already has one?
A.The residual current devices downstream would lose their ability to detect a phase-to-neutral short circuit.
B.The earth fault loop impedance at the sub-board would rise, delaying disconnection beyond the permitted time.
C.The neutral conductor beyond the second bond would have to be re-sized to at least twice the phase cross-section.
D.It creates parallel return paths, so normal load neutral current flows through protective conductors, water pipes and building metalwork.
Explanation: A second bond puts the neutral conductor and the protective conductor/metalwork in parallel between the two bonding points. Ordinary return current then divides between them in inverse proportion to their impedances, so operating current flows continuously over protective conductors and pipework (זרמי עבודה במוליכי הארקה). The result is touch-voltage risk, stray magnetic fields and unwanted tripping of residual current devices.
10In a dwelling installation, which circuits must be protected by a residual current device (מפסק מגן) with a rated residual operating current not exceeding 30 mA?
A.Every final circuit in the installation, including the bathroom and all socket-outlet circuits.
B.Only circuits feeding electric ovens and water heaters rated above 3 kW.
C.Only the main incoming feeder, ahead of any branching.
D.Only circuits dedicated to fire alarm panels and emergency escape lighting.
Explanation: The Electricity Regulations (Installation of Switchboards at voltages up to 1000 V) require a board in a dwelling installation to be fitted with one or more residual current devices such that every final circuit in the installation is protected against residual current exceeding 30 mA. The requirement is written against final circuits as a class, which is why socket outlets, lighting and bathroom circuits are all covered.

About the Israel Electrician Licensing Exam Exam

In Israel, carrying out electrical work is regulated under the Electricity Law, 5714-1954 (חוק החשמל, התשי"ד-1954) and the Electricity Regulations (Licences), 5745-1985 (תקנות החשמל (רשיונות), התשמ"ה-1985), which define twelve classes of electrician's licence and the current limits attached to each. The examination is administered by the Government Licensing Examinations Department in the Senior Division for Regulating Occupations at the Ministry of Labor (משרד העבודה). It is required for the three senior licence classes only — Electrician-Technician (חשמלאי-טכנאי), Electrician-Practical Engineer (חשמלאי-הנדסאי) and Electrician-Engineer (חשמלאי-מהנדס) — and candidates may choose it as an alternative to a professional interview before an advisory committee. Eligibility requires registration in the relevant register of technicians, practical engineers or engineers, plus at least two years of work as a Chief Electrician (חשמלאי ראשי). The computerised paper draws 50 multiple-choice questions from the Ministry's published question database, covering earthing and bonding methods, loop impedance and fault calculations, conductor loading and thermal protection, low-voltage switchboard standards, motor starting and power factor correction, and binding rulings of the Interpretation Committee (ועדת הפירושים). This resource provides independent English-language multiple-choice practice by OpenExamPrep to help professionals study the technical concepts, formulas and statutory provisions the Israeli examination tests. It is a study aid, not an official translation, not a reproduction of the official database, and not a simulation of the Hebrew-language examination environment.

Frequently Asked Questions

What is the official format and passing score for the Israeli electrical licensing examination?

The Ministry of Labor states that the examination comprises 50 multiple-choice questions worth 2 points each, that the time allowed is 3.5 hours, and that a passing grade is 80 points or more — that is, 40 correct answers out of 50. It is delivered as a computerised paper (בחינה ממוחשבת) at a designated government venue, and candidates are issued a calculator and a copy of the Electricity Law and Regulations for use during the exam.

What is the official question database (מאגר שאלות בחשמל)?

The Ministry of Labor publishes a free public question database. Version 8.1, dated August 2026 and last updated on 16 August 2026, contains 1,121 multiple-choice questions and marks which of them are reserved for the engineer, or engineer and practical engineer, papers. Examination questions are based on this database, but the Ministry warns that the wording, numbers or data may differ from the published version, and that the database may be updated up to 30 days before an examination.

Which licences require passing this examination, and is there an alternative?

It applies to the three senior licence classes only: Electrician-Technician (חשמלאי-טכנאי, low-voltage work including plans up to 3 x 400 A), Electrician-Practical Engineer (חשמלאי-הנדסאי, up to 3 x 630 A) and Electrician-Engineer (חשמלאי-מהנדס, unlimited). Candidates may instead sit a professional interview before an advisory committee to the Director. Lower classes such as Practical, Certified and Chief Electrician are obtained through the education and experience routes in the Regulations, not through this examination.

Who is eligible to sit the examination, and is there a fee?

Eligibility requires registration in the relevant register — the register of technicians or practical engineers in the electrical branch, or the register of engineers in the heavy-current or power-systems section — together with at least two years of work as a Chief Electrician. Applications must be filed at least 30 days before the examination date and registration closes about 21 days before. The Ministry's published 2026 schedule records the exam-fee deadline for the electrical sittings as 'not required' (לא נדרש).

In what language is the official examination delivered?

The official state examination is administered in Hebrew, and the question database is published in Hebrew only. The 100 practice questions on this page are an independent English-language multiple-choice study adaptation by OpenExamPrep, written to help English-speaking candidates learn the statutory provisions, technical terminology and calculation methods the examination tests. They are not an official translation, not a reproduction of the Ministry's database, and not a simulation of the Hebrew-language examination.

Does the Ministry publish a subject weighting for the examination?

No. The examination procedure states only that the material is drawn from the Electricity Law and Regulations, standards, technical literature and the professional knowledge required for the licence, and the published database is a flat numbered list rather than a weighted syllabus. The topic shares shown on this page describe how this practice bank is distributed across those subject areas; they are not an official blueprint.
