How does Electrical Power work? If you’re not electrically minded, think of 3 Phase vs Single Phase electric power as something easier to visualize like mechanical power. They’re very different, but both deliver power using pressure (force) and flow (speed). In both the po

Like most industries the electrical industry uses many acronyms. The ones most commonly associated with electrical control panels are UL508A, NEC, NEMA, and IEC. These are acronyms for the safety standards used to produce and install electrical control panels and electrical wiring sys

Electrical control panels are designed and used to control mechanical equipment. Each one is designed for a specific equipment arrangement and includes devices that allow an operator to control specified equipment. Electrical panel components control every piece of equipment in every

Electrical panel components are electrical power components when they’re used in electrical power circuits that power physical devices like Lighting, Heaters, Motors, etc. In the US, electrical power circuit wiring must follow the National Electric Code (NEC), a standard by the

Electrical panel components that are logical control devices are electrical control components. They’re used to control the sequence of events that define how a control panel functions. Some are manually actuated like a light switch and easy to understand. Let’s focus on e

NEMA Enclosure ratings define where an enclosure was designed to be used and the level of protection it was designed to provide. In the electrical world, NEMA stands for National Electrical Manufacturers Association, an association of US based equipment manufacturers that produce stan

Hazardous areas include potentially explosive vapors or dust. If these vapors or dust make their way into an electrical control panel, the normal arcing that occurs in electrical switching circuits could ignite these explosive vapors or dust and cause an explosion. The official hazard
