Transcriber’s Notes
Reading edition
The structure of the printed book regarding headings, sections and (sub-)sub-sections was inconsistent and occasionally unclear. As a consequence, there are some sub-sub-sections that are not part of sub-sections (for example, sub-sub-section national code rules for grounding, where there is no sub-section grounding). Inconsistent spacing of abbreviations, capitalisation, spelling and hyphenation have been retained. The alphabetic order of sections in Chapters XVIII and XIX is not always correct, this has not been changed. On various pages there are references to other sections and rules of the National Electric Code. These sections and rules are not listed as such, and it is therefore unclear whether the section or rule referred to is given in this work. Page 38, see Optics: it not clear to which chapter this refers, no link has been provided. Page 319: ... which should be used to the pin-plug connector ...: there is probably a word missing (“connect” or similar). Advertisement Automobile Hand-Book, ... over 720 pages: there is probably a word missing.
Changes made to the text: Illustrations have been moved out of paragraphs; footnotes have been moved to directly below the paragraph they refer to. Obvious minor typographical and punctuation errors have been corrected silently.
