Electrical tables and engineering data;
Electrical tables and engineering data, a pocket reference of formulas, dimensions and standards compiled by Henry C. Horstmann and Victor H. Tousley and published by F. J. Drake & Co. in Chicago in 1920 for electricians and wiremen. The line drawings are dimensioned plan views of cable lugs, terminal blocks, conduit boxes and trench sections, with letter callouts, arrowed dimension lines and catalogue numbers useful as schematic diagram vocabulary.
