1Under Ethiopian Building Code Standard EBCS 10 clause 4.4.1, what is the absolute minimum nominal cross-sectional area permitted for insulated copper conductors used in fixed electric power and lighting branch circuits?
A.1.0 mm²
B.1.5 mm²
C.2.5 mm²
D.0.75 mm²
Explanation: EBCS 10 clause 4.4.1(a) establishes 1.0 mm² as the absolute minimum cross-sectional area for fixed insulated copper conductors serving general power and lighting circuits in building installations. While standard domestic lighting circuits commonly employ 1.5 mm² for mechanical robustness, 1.0 mm² remains the legal statutory minimum permitted by the code.
2According to EBCS 10 clause 4.5.4, what is the maximum allowable voltage drop between the service intake terminal and any point of utilization or outlet carrying full design load?
A.4.0%
B.2.5%
C.5.0%
D.3.0%
Explanation: EBCS 10 clause 4.5.4 specifies that the total voltage drop between the main consumer intake terminals and any point of outlet or fixed current-using equipment must not exceed 4.0% of the nominal supply voltage. On a standard single-phase 230 V supply in Ethiopia, this limits the maximum allowable drop to 9.2 V.
3What is the standard minimum conductor cross-sectional area required by EBCS 10 for copper wiring feeding general 13 A or 16 A radial socket-outlet circuits in residential buildings?
A.2.5 mm²
B.1.5 mm²
C.4.0 mm²
D.6.0 mm²
Explanation: In residential electrical installations governed by EBCS 10, radial circuits serving general-purpose 13 A or 16 A socket outlets protected by a 16 A or 20 A overcurrent protective device require a minimum conductor cross-sectional area of 2.5 mm² copper to safely carry the design load without thermal degradation or excessive voltage drop.
4An electrician replaces the flexible cord on a portable single-phase appliance. Under EBCS 10 Table 4.1, which core colours identify the phase, the neutral and the protective conductor of that flexible cord?
A.Phase brown, neutral blue, protective conductor green-and-yellow
B.Phase red, neutral black, protective conductor green-and-yellow
C.Phase black, neutral white, protective conductor plain green
D.Phase brown, neutral black, protective conductor bare copper
Explanation: EBCS 10 keeps two separate colour tables. Table 4.1, for the cores of flexible cables and cords, gives the phase as brown, the neutral as blue and the protective conductor as green-and-yellow. Table 4.2, for non-flexible cable and bare conductors in fixed wiring, is different: phase R red, phase Y yellow, phase B blue, neutral black, protective conductor green-and-yellow. Applying the fixed-wiring colours to a flexible cord — or the reverse — is a classic cross-connection error.
5What is the maximum space factor (conduit fill percentage) permitted when pulling three or more insulated building wires into a rigid PVC or steel conduit system?
A.40%
B.60%
C.50%
D.30%
Explanation: Conduit-fill tables used in general installation practice cap the space factor at 40% once a conduit carries three or more conductors. Limiting the total cable cross-sectional area (including insulation) to 40% of the internal conduit area prevents excessive drawing friction, avoids insulation damage during pulling, and permits adequate heat dissipation. EBCS 10 does not publish its own space-factor table, so the 40% figure comes from the conduit-fill practice the code's parent standards use.
6A single-phase 230 V water heater circuit carries a continuous design load current of 12 A over a distance of 20 meters using 2.5 mm² copper cable (conductor resistivity ρ = 0.0175 Ω·mm²/m). What is the total voltage drop on this circuit?
A.3.36 V
B.1.68 V
C.6.72 V
D.4.80 V
Explanation: The loop length for single-phase is 2 × length = 2 × 20 m = 40 m. Conductor loop resistance R = (ρ × 2L) / A = (0.0175 × 40) / 2.5 = 0.70 / 2.5 = 0.28 Ω. Voltage drop Vd = I × R = 12 A × 0.28 Ω = 3.36 V. As a percentage: (3.36 / 230) × 100 = 1.46%, which is well within the 4.0% EBCS 10 limit.
7When calculating the minimum ampacity of the service or feeder conductors for a single-family dwelling under EBCS 10 clause 6.5.1, what allowance must be added for an electric "Injera Mitad"?
A.3,500 W
B.1,000 W
C.2,500 W
D.6,000 W
Explanation: EBCS 10 clause 6.5.1 builds the single-family dwelling calculated load from a basic 2,500 W for the first 70 m² of living area, plus 1,000 W for each further 70 m² or part of it, plus 3,500 W for any electric "Injera Mitad", plus 6,000 W for a single cooking stove rated 12 kW or less (plus 40% of any excess above 12 kW), plus any electric water heater at a demand factor of 100%. The Injera Mitad is written into the Ethiopian code as its own fixed 3,500 W allowance.
8EBCS 10 normally requires an earthing or bonding conductor sharing a raceway with the circuit conductors it serves to be insulated. Under which limitation may an uninsulated conductor be used instead?
A.The raceway is not longer than 15 m and contains no more than the equivalent of two quarter bends between pull points
B.The raceway is not longer than 30 m and contains no more than four quarter bends between pull points
C.The raceway is rigid non-metallic conduit and contains no bends at all
D.The conductor is 25 mm² or larger and the raceway is buried below floor level
Explanation: EBCS 10 Section 7 permits the exception only where the run is short and easy to draw: the raceway must not exceed 15 m between pull points and must not contain more than the equivalent of two quarter bends between those pull points. Outside that limit the earthing or bonding conductor must be insulated, because a long or heavily bent pull can abrade a bare conductor against the live conductors sharing the raceway.
9Under EBCS 10 clause 6.4.3, what is the maximum continuous design load that may be placed on a branch circuit overcurrent protective device?
A.80% of the nominal device rating
B.100% of the nominal device rating
C.70% of the nominal device rating
D.90% of the nominal device rating
Explanation: EBCS 10 clause 6.4.3 stipulates that circuits feeding continuous loads (defined as loads running continuously for 3 hours or more, such as commercial lighting or water heating) must not be loaded beyond 80% of the protective device rating. Alternatively, the protective device and cable must be rated for at least 125% of the continuous load current.
10When four multi-core PVC-insulated copper cables are installed bunched together in an enclosed trunking system at an ambient temperature of 30°C, what grouping derating factor (Cg) must typically be applied to their tabulated current-carrying capacity?
A.0.65
B.0.80
C.0.90
D.0.50
Explanation: Standard cable grouping tables (IEC 60364-5-52 / EBCS 10) prescribe a grouping derating factor of Cg = 0.65 for four multi-core cables bunched together on a surface or enclosed in trunking. This accounts for mutual heating, reducing each cable's effective ampacity to 65% of its single-circuit tabulated rating.

Frequently Asked Questions

What is the Ethiopian Energy Authority Electrician Competency Certificate?

It is the statutory professional competency certificate issued by the Petroleum and Energy Authority (PEA, formerly the Ethiopian Energy Authority — EEA) under Energy Proclamation No. 810/2013, Council of Ministers Energy Regulation No. 447/2019, and the Electrical Works Professional Competency Certification Directive No. 1/2011 E.C. No person may undertake electrical work activities without obtaining a certificate of competency from the Authority.

Which types and grades of electrical work certificate does the Authority issue?

The Authority issues professional competency certificates in three types of electrical work: electrical installation, electrical design and supervision, and electrical inspection and testing. Each type is graded, with Grade 1 the highest and Grade 4 the entry grade, and an applicant registers for one type at one grade. The Authority determines the grade from the applicant's qualification, verified work experience, and performance in the written and practical examination.

What qualifications and documents are needed to apply?

The Authority accepts several educational routes according to the grade applied for: a qualification in electrical engineering, electrical/electronics technology or electro-mechanical engineering; a BEd related to teaching the electrical trade; an electrical certificate at the relevant level from a technical and vocational training college; a 60-hour training certificate from a recognised institution; or a Level 1 COC certificate. Applicants also submit two 3×4 photographs taken within the previous six months plus work experience evidence, where experience not directly related to electrical work counts at half weight. Applications are filed online through the Ethiopian eServices portal.

What are the official fees, and how long is the certificate valid?

Under Energy Regulation No. 447/2019 Article 20 the total service fee is ETB 363.98 for Grade 3 and ETB 242.66 for Grade 4 (ETB 606.64 for Grade 1 and ETB 485.31 for Grade 2), covering registration, the written examination, the practical examination and certificate issuance. A certificate of competency is valid for two years from its date of issuance and must be renewed at least 15 days before expiry; a holder who misses that deadline may still apply within 90 days of expiry on payment of a penalty fee.

Is this practice question bank an official EEA/PEA examination paper?

No. The official assessment is a written examination plus a hands-on practical examination, and the Authority publishes its certification materials in Amharic. This bank is an independent English-language multiple-choice study adaptation covering the technical knowledge, code rules and calculations behind that assessment. It is not published, endorsed or translated by the Petroleum and Energy Authority, it does not simulate the official paper, and it cannot replace supervised practical workshop preparation.
