Book Description
Excerpt from Electric-Wiring, Diagrams and Switchboards The elementary relationship oi volts, amperes, and ohms is given first consideration; then the pivotal point of drop of potential is emphasized and ex panded, and the first applications of this idea brought, as is believed, clearly to the reader's attention. Means of calculating drop, ' finding the circular mils of the wire, and arriving at its numbered gauge Size without a table are given. Thismay be regarded as the pri mary object of the book, and will be considered by wiremen who master this method as well worth the slight labor involved. The further expansion of the simple circuit into others of a more complex type rep resents the next stage of progress. From this step on, the subject matter leads into a consideration of the principles of switchboard design, with reference to shunt and compound wound generators. The appa ratus employed on switchboards is of great importance in electric lighting. Though, as is commonly sup posed, the switchboard represents the means by which all important circuits are concentrated and controlled; it is also the measuring and protective, as well as the distributing center of the electric light or power sys tem. Wiring embraces this, as well as the moulding and pipe work, as will be readily understood by the intelligent reader. It 15 incompletely treated, however, unless the meaning of alternating current phenomena which relate to wiring; as well as simple arithmetical methods of getting the sizes of wire for such circuits, also receive careful attention.
