Electrical & Power

Cables, distribution, protection and earthing explained — how power reaches every point safely and efficiently.

Types of Electrical Cables and When to Use ThemA practical guide to electrical cable construction, the difference between conductor and insulation choices, and the main cable types used in UAE building and infrastructure projects, with sizing and code notes.7 min read

How an Electrical Distribution Board WorksAn electrical distribution board (DB) takes a single incoming supply and splits it safely into many protected final circuits. This guide explains each part and how protection coordinates from incomer to socket.6 min read

Earthing and Bonding ExplainedEarthing gives fault current a safe path back to source and keeps exposed metal at a safe voltage, while bonding ties metalwork together so no dangerous voltage can appear between parts. Together they are the backbone of electrical shock protection.6 min read

How to Size a Circuit Breaker: A Practical GuideA field-focused guide to selecting the correct circuit breaker rating and characteristics. Covers design current, device rating, cable capacity, the Ib <= In <= Iz coordination rule, breaking capacity in kA, B/C/D trip curves, and how UAE regulations apply.6 min read

Power Factor Correction ExplainedA practical engineering guide to power factor correction (PFC) for buildings and facilities. It explains real, reactive and apparent power, the power triangle, why inductive loads drag power factor down, how capacitor banks and APFC panels supply reactive power locally, why detuned reactors are needed where harmonics are present, and the cost benefits of higher PF in the UAE.7 min read
