For Electrical and Mechanical Engineers working in Qatar’s construction, MEP, or facility management sectors, obtaining KAHRAMAA Certification from the Qatar General Electricity and Water Corporation (KAHRAMAA) is a mandatory milestone.
A KAHRAMAA Contractor/Engineer License authorizes professionals to design, inspect, test, submit, and sign off on electrical and plumbing installations connected to Qatar's national grid and water supply network.
KAHRAMAA Licensing Grades & Eligibility
KAHRAMAA issues engineer licenses across distinct grades based on technical qualifications, total verified experience, and performance in the written/oral examinations:
| KAHRAMAA License Grade | Maximum Power / Scope Allowance | Minimum Experience Required |
| Grade A | Unlimited KVA (High Voltage / Major Complexes) | 10+ Years verified experience |
| Grade B | Medium Voltage / Up to 1,000 KVA Installations | 7+ Years verified experience |
| Grade C | Low Voltage / Standard Residential & Commercial | 4–5 Years verified experience |
Mandatory Prerequisites before Applying
To be eligible to sit for the KAHRAMAA examination, candidates must hold:
Attested Engineering Degree: Bachelor of Science in Electrical Engineering, Mechanical Engineering, or Power Electronics attested by MOFA Qatar and home country authorities.
Valid UPDA / MMUP Registration: An active UPDA engineering license issued by the Ministry of Municipality.

Step-by-Step Registration & Examination Process
Key Topics Covered in the KAHRAMAA Electrical Exam
KAHRAMAA Wiring Regulations: Minimum cable sizing, color coding standards (Red/Yellow/Blue or Brown/Black/Grey), earthing (TT & TN-S systems), and neutral protection.
Substation & Switchgear Design: Transformer ratings, ring main units (RMU), circuit breaker breaking capacity, and busbar calculations.
Protection Systems: Residual Current Devices (RCD/ELCB sensitivity 30mA for socket outlets, 300mA for general lighting), circuit breakers (MCB, MCCB, ACB), and overcurrent coordination.
Power Factor Correction: Capacitor bank calculations to maintain power factor above $0.92$ lagging as required by KAHRAMAA utility tariffs.
