IG-250 – Comprehensive Grounding and Bonding (12 labs) (4 days)

IG-250 Course

iGround – What Sets Our Training Apart (PDF)

Our flagship training course addresses advanced grounding/bonding/site survey methods with a heavy emphasis on electrical safety, equipment operation, lightning protection, and other grounding/bonding considerations. This course is specifically designed to increase the knowledge base for any technical team. The twelve (12) labs reinforce the knowledge to understand key issues to any site installation, including SATCOM, cellular, Outside Plant/Inside Plant (OSP/ISP), and data centers. Whether you’re in Quality Assurance, installation, or a technician, the hands-on test labs and proven troubleshooting methods, data collection/analysis, and data presentation techniques will have you poised for success.
