Description
A fascinating look at early 20th-century switchboards for power, light, manufacturing, and transportation.
Hervey S. Walker first published this detailed illustrated guide to switchboards in 1911 for engineers across America who built the great industrial complexes that grew the United States into an economic powerhouse with operations controlled by switchboards.
This classic book is enhanced by hundreds of photographs of the fronts and backs of switchboards, knife switches, gauges, choke coils, lighting arrestors, panel boards, radial voltmeter switches, classic engineering diagrams, and more. Engineering historians and electrical engineer enthusiasts will enjoy this unique look at the bygone era of industrial controls and operations that ran factories, manufacturing plants, ships, railroads, newspapers, apartment buildings, and more.
