: Typically used for residential buildings and light electrical loads.
: Power enters a building via underground or overhead cables from the main grid.
: Essential features like earthing provide a path for leakage current to prevent shocks, while Residual Current Devices (RCDs) and surge protectors safeguard against overloads and lightning. Types of Electrical Supply
: Used in commercial, institutional, or industrial settings to power heavy machinery and high-occupancy equipment. Specialised Design Services
Electrical services are the critical systems that ensure power is safely and efficiently delivered to residential, commercial, and industrial buildings. These services encompass everything from the initial connection to the utility grid to the final outlets used by occupants. Core Components of Electrical Services
: A metering unit measures consumption, while a distribution board (DB) divides power into various circuits, each protected by a fuse or Miniature Circuit Breaker (MCB) .
: Connects switches, sockets, and appliances to the distribution board. This includes various wiring methods and conductor materials like copper or aluminium.
Modern electrical engineering design often includes integrated systems such as:
