Panel building is the process of assembling electrical control panels that house various components like circuit breakers, relays, and switches. These panels are essential for controlling and distributing electrical power in industrial and commercial settings. Skilled technicians ensure that all components are correctly installed and wired according to specific electrical codes and standards. The panels are typically housed in metal or plastic enclosures to protect the internal components from environmental factors. Once assembled, the panels undergo testing to verify their functionality and safety before being installed in their intended locations, such as manufacturing plants or data centers.
