Episode 8: Power and Distribution (Construction Science Principles)
Get a clear, no-fluff walkthrough of how electricity is generated, stepped up/down, and safely delivered to sites and buildings. We cover AC vs DC, single- vs three-phase, why 110 V is used on construction sites, and the protection devices that keep people safe. Plus, the key UK regs you must know to stay compliant.
What you’ll learn:
How power is generated and distributed (grid, transformers, 230 V/400 V star systems)
AC vs DC and why 110 V CTE is used on sites
Fuses, MCBs, RCDs, RCBOs and how ADS/disconnection times work
Earthing and earth loop impedance (Zs) in practice
The essential regs: BS 7671:2018+A2:2022, EAWR 1989, Part P, ESQCR 2002, CDM 2015, and key BS EN device standards
