Electrical tables and engineering data; a book of useful tables and practical hints for electricians, foremen, salesmen, solicitors, estimators, contractors, architects and engineers
A 1916 Chicago trade handbook of electrical tables and shop data compiled by Henry C. Horstmann and Victor H. Tousley for working electricians, contractors, estimators and architects. The 42 plates are plain black line diagrams: dimensioned panel and cabinet layouts with dotted outlines and arrow-and-tick measurement marks, dot-and-line wiring schematics with lettered terminals, plan views of fuse blocks and screw terminals, and sectioned elevations of switches and fittings.
