If you did electrical construction work for the City of Baltimore in 1923, you could pick up a handy small reference book that would fit comfortably in your toolkit or tool-belt, because this petite volume with the cover title, “Rules and Regulations for the Construction of Electrical Work in the City of Baltimore, issued by the Inspector of Buildings,” is only 168 pages and just 6 inches by 4 inches. Issued as a paperback, this soft cover electrical code reader, complete with a 14 page “Index to Rules,” has everything you need to stay up to date with Baltimore city ordinances, especially building inspector requests and requirements.

The electrical engineer who uses this book is empowered to know and cite the rule or regulation regarding the installation of any type of motor, low or high power systems, wiring and switches for indoor and outdoor use, and of course, arc lamps popular in the home and in movie and theater houses all before the inspector of buildings comes to check out the finished project.
