Скачать или смотреть Main Cable Design 101 🔌 | Cable Sizing, Voltage Drop & Faults Made Easy

How do professional engineers design and size main electrical cables safely and efficiently?
In this Electrical Engineering 101 tutorial, we’ll break down how to calculate cable sizes, manage voltage drop, and design low-voltage distribution systems using real-world engineering principles.

You’ll learn:
✅ How to calculate current capacity and voltage drop correctly
✅ How to use the adiabatic equation for short-circuit and fault protection
✅ How to understand disconnection times under BS 7671 and IEC standards
✅ When to use copper vs aluminium conductors
✅ How to identify XLPE, LSF, and harmonised cable types (H07RN-F, etc.)
✅ Real tips from professional building services design

Whether you’re an electrical engineer, a student, or simply learning the basics — this is the foundation of safe and efficient electrical design.
