At Jumba Engineering Services Ltd (Jumba Engineering), safety and reliability are not afterthoughts — they are built into every stage of our engineering processes. With over 40 years of experience in electrical contracting and infrastructure development, we understand that rigorous evaluation and testing are the foundation of systems that last.
Our evaluation segment focuses on:
-
Risk Identification & Analysis – Every project begins with a comprehensive review of potential hazards, in line with IEC 60364 and IEEE standards, to ensure designs meet the highest safety benchmarks.
-
System Integrity Testing – From transformers and switchgear to structured cabling and solar systems, our engineers perform insulation resistance, continuity, earth loop, and functionality tests using calibrated instruments.
-
Load & Performance Verification – Before handover, all installations undergo simulated load testing to verify capacity, efficiency, and long-term stability.
-
Regulatory Compliance – JES Ltd is licensed under EPRA (A1) and NCA1, and all works conform to Kenyan Electrical Codes of Practice, OSHA 2007, and IEC global guidelines.
We believe that a system is only as strong as its weakest link. That’s why our evaluation testing goes beyond compliance; it is a commitment to excellence, safety, and sustainability. This segment has enabled us to deliver reliable systems for partners such as Two Rivers Mall, KenGen, the Central Bank of Kenya, and Garden City Mall.
Our Promise: Every project tested by Jumba Engineering is engineered to perform — today, tomorrow, and for decades to come.
