Here are some reference books that explain the differences between isolators and switch disconnectors (TPN), as well as between earth faults and short circuits:
1. "Electrical Installation Design Guide: Calculations for Electricians and Designers" by Paul Cook - This book provides a comprehensive guide to electrical installation design, including explanations of isolators, switch disconnectors, earth faults, and short circuits.
2. "Electrical Installation Work" by Brian Scaddan - This book covers the principles and practices of electrical installation work, including detailed explanations of isolators, switch disconnectors, earth faults, and short circuits.
3. "Electrical Wiring Residential" by Ray C. Mullin and Phil Simmons - This book focuses on residential electrical wiring, but also includes explanations of isolators, switch disconnectors, earth faults, and short circuits in a residential context.
4. "Electrical Power Systems: Design and Analysis" by Dr. Mohamed E. El-Hawary - This book provides a comprehensive overview of electrical power systems, including discussions on isolators, switch disconnectors, earth faults, and short circuits.
5. "Electrical Safety Handbook" by John Cadick, Mary Capelli-Schellpfeffer, and Dennis Neitzel - This handbook covers various aspects of electrical safety, including explanations of isolators, switch disconnectors, earth faults, and short circuits, with a focus on safety considerations.
These reference books should provide detailed explanations and insights into the differences between isolators and switch disconnectors (TPN), as well as between earth faults and short circuits.
