This book is a first-of-its-kind practical troubleshooting guide for reducing magnetic fields due to wiring errors and grounding practices, written for the electrician, contractor, architect, inspector, utility engineer, safety engineer, and do-it-yourself remodeler. The book is based on the finding that the most common sources of AC magnetic fields over 3 mG in substantial areas of living space are mis-wired circuits and legal but correctable grounding currents. The book explains in detail how to detect National Electrical Code violations, trace, and correct them. It provides an evaluation of building grounding practices with recommended low-field alternatives which meet the Code.
