Electrical Panels are central control units that house the electrical and automation components needed to operate machinery and industrial systems. Think of them as the 'brain' of industrial equipment, containing switches, buttons, displays, and control devices. They're essential in manufacturing plants, buildings, and industrial facilities, helping workers monitor and control various equipment. These panels can range from simple on/off control boxes to complex automation centers that run entire production lines. When candidates mention experience with electrical panels, they're typically referring to either building these panels, maintaining them, or programming their functions.
