We always have a great time working on Automation Notebook but this one was extra special as we hit our 40th issue! It’s always exciting to see another one come together after weeks of hard work. This month we took a look at enclosures in our panel builder checklist and our article on how to select and size enclosure thermal management systems. Brush up on your NEMA ratings and learn a few simple tricks to avoiding wiring errors. This issue is chock full of useful information to keep your systems running smoothly. As always, check out our brainteasers in the back of the issue for a midday jolt of brain power. We hope you enjoy!

Panel Builder Checklist

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…

Avoid Wiring Errors

In a Control Design September 2018 Automation Basics column titled “Terminate the Rat’s Nest”, author Dave Perkon gets right to the point when he writes, “For those who think it’s okay to open a control enclosure and see a monochromatic rat’s nest of wires without any wire labels, you should be aware, that’s worst-case practice.”…

How to Select and Size Enclosure Thermal Management Systems

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….

Arc Suppression – the Afterthought that Could Save Your Life

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…
