Switchrack for electric motor starters and controls

Abstract

Abstract An improved metal switchrack for mounting weatherproof and explosionproof self contained electric motor starters and electric motor controls as they are commonly manufactured and used by the electrical industry; and more particularly, as they are applied to motor control systems of the petroleum industry; chemical industry; and industries using motors and starters which are to be installed in areas surrounded by atmospheres containing hazardous concentrations of flammable gases, combustible dusts, ignitible fibers or flyings. That which is new is an adaptable and adjustable prefabricated motor switchrack that can be erected at the site of installation which will accommodate mountings of any combination of selfcontained electrical motor starters and self-contained electrical motor controls of standard sizes. An infinite number of combination mountings of switchrack electrical components heretofore described are possible on my switchrack by utilizing an adjustable mounting plate which supports the electric motor starter or electric motor control. The adjustable mounting plate slides horizontally on a predrilled channel to the selected location and the aligning pins engage into the predrilled aligning holes and is clamped into final position by means of an adjustable pressure clamp.
