Building the Electrical Control Panel There are many things to consider when building an automation control system. Some control systems are extremely simple, like a pump control system that consists of a pump, level controller, and a contactor, or they can be complicated and control a full production line with a series of sub control…

Electrical control systems are used on everything from simple pump controls to car washes, to complex chemical processing plants. Automation of industrial machinery, tools and more has increased productivity and reliability in all areas of manufacturing, utilities and material processing. When an operation or process used to produce an end product is very laborious, time…

Housing electrical components inside an enclosure in industrial applications facilitates the protection of controllers, power distribution components, power supplies and other electronics from harsh factory floor environments. Factories, plants and facilities often experience considerably warm ambient temperatures, and many of the electrical components housed in the control enclosure generate heat, so many enclosures require cooling….

Those of us who have worked with, or around, electrical equipment have witnessed electrical arcs. At the very least, we’ve seen the sparks produced when a relay or contactor switches off. This is easily observed by watching a motor starter with open contacts. When the motor turns on, the contacts close in a fairly uneventful…
