Whether you're studying to be an electrician, or a seasoned professional looking to improve your blueprint-reading skills, this newly-revised Electrical Blueprint Reading Revised manual will help you stay competitive in today's electrical job market. This book shows you 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.
You'll 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 panelboard, connected-load, and other schedules.
This new edition provides:
- Dozens of drawings, diagrams, and blueprint reproductions, recently redrawn and updated
- Sample electrical specifications and forms
- Sample problems and a Final Exam (answers included)
- A glossary of terms and a guide to electrical symbols
Reading a blueprint is like reading a road map. It tells you exactly what you're required to build. Read it wrong and you'll build it wrong - and that can be expensive. This Electrical Blue Print Reading Revised book will teach you how to get the information you need from the most complex electrical blueprints. Once you understand how to follow the pathways and interpret the scale and symbols, you can install the correct system the way the designer intended. Keep this Electrical Blueprint Reading book as a handy reference. Once you've learned the techniques it explains, you'll no longer face the bewilderment and frustration of having to build from electrical blueprints you can't read.
ELECTRICAL DRAWINGS: |
An electrical blueprint is an exact copy or reproduction of an original drawing, consisting of lines, symbols, dimensions, and notations to accurately convey an engineer's design to workmen who install the electrical system on the job. The student should keep in mind that the workmen must be able to take a blueprint, and without further instructions, install or produce the electrical system as the engineer or draftsman intended it to be accomplished. A blueprint, therefore, is an abbreviated language for conveying a large amount of exact, detailed information, which would otherwise take many pages of manuscript or hours of verbal instruction to convey.
In every branch of electrical work, there is often occasion to read an electrical drawing. Electricians, for ex- ample, who are responsible for installing the electrical system in a new building, usually consult an electrical drawing to locate the various outlets, the routing of circuits, the location and size of panelboards, and other similar electrical details, in preparing a bid. The electrical estimator of a contracting firm must refer to electrical drawings in order to determine the quantity of material needed. Electricians in industrial plants consult schematic diagrams when wiring electrical controls for machinery. Plant maintenance men use electrical blueprints in troubleshooting. Circuits may be tested and checked against the original drawings to help locate any faulty points in the installation.
