New YORK CITY:
Electric wiring is not generally well understood. To the average electrician there is a certain amount of mystery connected with the art; yet it is only a matter of simple arithmetic, which any person with ordinary perseverance, can easily master. It is the object of the following pages to furnish the student with such rules and suggestions, as to enable him to solve this problem himself. There is a call for a treatise of this character, to which the present effort is a response. A unique feature of this work is newly compiled tables of the arc and motor wiring systems, brought down to date.
