The Inspector chapter is designed for candidates pursuing dual Journeyman/Inspector or Master/Inspector certification in a single study cycle — a tier not found in competing titles at this price point.Walk into your state exam fully prepared. Each chapter maps directly to the exam domains weighted most heavily by state licensing boards: branch circuits, grounding and bonding, wiring methods, and load calculations.
