Electrical Blueprint Reading

Reading a blueprint is like reading a road map. It tells you exactly what you are required to build. Read it wrong and you will build it wrong -- and that can be expensive. This book explains how to read and interpret all types of electrical drawings and diagrams used in residential and commercial construction. There are details on electrical floor plans, lighting layouts, and schematics showing single line and block or power-riser diagrams for wiring circuits. Learn how to lay out an electrical project, what to look out for in dealing with construction specifications and drawings -- especially in terms of today's technology, how to use an engineer's scale for developing and reading site plans, and how to make up and use panel board, connected-load, and other schedules.

Using terminology and applications unique to the electrical industry, this book provides a strong, relevant introduction to reading and interpreting blueprints for aspiring electricians. Blueprint Reading for Electricians, 2E begins by covering fundamental tools and basic sketching, and progresses to include coverage of views, plans, schedules, and specifications. With additional chapters devoted to the types of prints found in a set of construction drawings and clear explanations of their relationships to various electrical installations, the book offers content that is both comprehensive and applicable. Need-to-know mathematical concepts are covered in a straightforward manner, so that readers can feel confident they have sufficient knowledge to learn and apply the material. Both a training manual and blueprint reading reference, Blueprint Reading for Electrical Workers, 2E provides the content, the hands-on exercises, and the real-world applications necessary for readers to master their print reading skills.

The book's purpose is to provide you with the ability to build since this will lead you to great financial achievement into the construction business. Electrician, Electrical apprentice, with the desire to make a career in the electrical field will benefit from the experience of thousand and hundreds of hours spend in the construction sites. This book is the valuable tool for any individual involved in electrical field as beginner that performs tasks as electrician, estimator, apprentice or engineer. Contractors will discover information they need in their business. The book is the perfect for any new emigrant that intends to make a career in the construction business as electrical contractor or electrician. To make it more affordable is coming in black &white version but is available in full color version also. The full-color version will be able to provide more clarity and easy understanding of the pictures, sketch, drawings and diagrams. Limited preview on www.books.google.com

Chapter 1 BLUEPRINTS When you have read and understood this chapter, you should be able to answer the following learning objectives: Describe blueprints and how they are produced. Identify the information contained in blueprints. Explain the proper filing of blueprints. Blueprints (prints) are copies of mechanical or other types of technical drawings. The term blueprint reading, means interpreting ideas expressed by others on drawings, whether or not the drawings are actually blueprints. Drawing or sketching is the universal language used by engineers, technicians, and skilled craftsmen. Drawings need to convey all the necessary information to the person who will make or assemble the object in the drawing. Blueprints show the construction details of parts, machines, ships, aircraft, buildings, bridges, roads, and so forth. BLUEPRINT PRODUCTION Original drawings are drawn, or traced, directly on translucent tracing paper or cloth, using black waterproof India ink, a pencil, or computer aided drafting (CAD) systems. The original drawing is a tracing or “master copy.” These copies are rarely, if ever, sent to a shop or site. Instead, copies of the tracings are given to persons or offices where needed. Tracings that are properly handled and stored will last indefinitely. The term blueprint is used loosely to describe copies of original drawings or tracings. One of the first processes developed to duplicate tracings produced white lines on a blue background; hence the term blueprint. Today, however, other methods produce prints of different colors. The colors may be brown, black, gray, or maroon. The differences are in the types of paper and developing processes used. A patented paper identified as BW paper produces prints with black lines on a white background. The diazo, or ammonia process, produces prints with either black, blue, or maroon lines on a white background. Another type of duplicating process rarely used to reproduce working drawings is the photostatic process in which a large camera reduces or enlarges a tracing or drawing. The photostat has white lines on a dark background. Businesses use this process to incorporate reduced-size drawings into reports or records. The standards and procedures prescribed for military drawings and blueprints are stated in military standards (MIL-STD) and American National Standards Institute (ANSI) standards. The Department of Defense Index of Specifications and Standards lists these standards; it is issued on 31 July of each year. The following list contains common MIL-STD and ANSI standards, listed by number and title, that concern engineering drawings and blueprints.
