An essential step in electrical design is estimating the likely load requirements  of a building. This process provides the foundation for selecting electrical equipment, designing distribution systems, and ensuring long-term energy efficiency and safety. At NEXUS M&E Design , we begin with a careful evaluation of load requirements  based on the building’s total area and intended use. The most practical approach is to apply unit loading values (W/m²) , determined statisticall

Electrical power isn’t always straightforward — not all the electricity you draw is actually used to do work . Let’s break it down 👇 🔹 Active Power (P) – The Useful Power This is the real, usable power  that does actual work — like heating, lighting, or running a motor. Unit:  Watts (W) Formula:  P = V × I × cosφ Example 1: 💡 A 100W light bulb uses 100W  of active power .All the power is converted into light and heat — simple and efficient. Example 2: 🌀 A 2kW electric hea

Switching from a traditional oil-fired non-condensing boiler to a modern condensing combi boiler might seem like an easy solution, but...

When upgrading to modern heating systems like heat pumps or condensing boilers, radiator sizing is critical to ensure efficient heating....
