PREFACEThis new edition of a popular pocket reference contains much new material. The pocket size has much new information inserted
where needed to bring it up to date.
The value of the new edition has been enhanced by its more compact format that allows you to locate your information more
quickly. Information in this edition has been updated to reflect changes in the latest edition of the National Electrical Code (also
known as the Code).The purpose of this book is to aid you in your everyday tasks and
keep you updated with the latest facts, figures, and devices in this important trade.
Many illustrations are included, which show a variety of parts and techniques found in present day practice in the field. Obviously,
not all related problems can be presented here, since there is a great deal of ingenuity required by the worker on the job. For standard procedure, however, the National Electrical Code handbook does give a guide to the number of wires and types of equipment
that is safe to install in a given location. This handbook should be a part of your tool kit
