🎯 Course Description:
This 5-day technical training course provides a comprehensive understanding of earthing (grounding) and bonding systems, with a focus on personnel safety, equipment protection, electromagnetic compatibility (EMC), and lightning protection in industrial, utility, commercial, and hazardous environments.
Participants will learn about earthing design principles, grounding system types, potential rise, touch and step voltage, lightning risk assessment, and how to comply with standards such as IEC 60364, IEEE 80, NEC, and BS EN 62305. Real-world case studies and hands-on workshops ensure participants can design, assess, and troubleshoot grounding systems effectively.
