Original electrical trade vintage catalog for CONDIT ELECTRICAL MANUFACTURING COMPANY, was located in Boston, MA. Manufacturers of protective devices, including oil starters and switches, fuses, relays and transformers. The type I fused oil switch is used in starting small induction motors which are thrown directly on the line without the use of a starting compensator. Disbound from a large 1916 architect construction materials book, this unique old one page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro electrical equipment library. Contains a small amount of residual glue on edge.
