How to Pass the Electrical Exam

<p>This book is written to help prepare an electrician for an alarm examination. The correct installation of an alarm system is very critical when lives and property are being protected. Many states are now requiring electricians to be tested and licensed prior to installing alarm systems. Alarm installation must conform to the applicable National Electrical Code (NEC) which is the minimum requirements permitted. Local codes can be more stringent than the NEC. The difference between general wiring and alarm wiring is open circuits are supervised. This book will explain different types of circuits such as open loop, closed loop, Class 1, Class 2, Class 3, power-limited, nonpower-limited, remote-control, fire protective signaling systems, supervised circuits, non-supervised circuits, etc. This workbook will cover the questions from the alarm exam from the NEC, OSHA, UL, NFPA, Business Law, etc. with a final exam from each section. This exam workbook will help you become more familiar with the NEC, OSHA, UL, NFPA and Business Law. Knowing where to find the answer to an exam question within the allowed time is the key to passing the exam.</p>
