"Electrical Inspections from the Grounds Up"

Electrical systems are installed with myriad details. Understanding the differences between grounded, grounding and bonding conductors is not intuitive. Electrical services, panelboards and subpanels must be installed properly. The details for installation of wiring systems are very important. GFCI and AFCI protection have very different functions. Surge protection and emergency power installations are becoming common. Wiring installations in homes can be safe or scary. This seminar will help home inspectors go beyond minimum inspection requirements and provide a better understanding of how to evaluate and report on the electrical installations in homes to make sure they are properly installed and safe.
