Furthermore, you should have routine maintenance done by a professional electrician at least once every three years.
Commercial and Industrial Power distribution
Power distribution systems used in multi-family, commercial, and industrial facilities are more complex. A power distribution system consists of metering devices to measure power consumption, main and branch disconnects, protective devices, switching devices to start and stop power flow, conductors, and transformers.
Panelboard Definition
The National Electrical Code® (NEC®) defines a panelboard as a single panel or group of panel units designed for assembly in the form of a single panel, including buses and automatic overcurrent devices, and equipped with or without switches for the control of light, heat, or power circuits; designed to be placed in a cabinet or cutout box placed in or against a wall, partition, or other support; and accessible only from the front (Article 1 00-Definitions)..

Organized Electrical Distribution
To the layman or anyone who isn’t knowledgeable about electrical installation, a panel board will most likely look like just another storage box or a seemingly innocuous metal plate on the wall.
Protection of Fragile Electronic Components
The electrical parts placed within a panel board are placed there not just for easy management, but also for protection from unwanted matter. Circuit breakers, open wires, and electrical panels should not be left out in the open because even the slightest drop of water or a sudden impact on it can easily damage it.
Personal and Structural Security
Panelboards greatly help in ensuring that people within an establishment are free from harm’s way—particularly those caused by electrical problems such as short circuits, and circuit overloads.
Key Takeaway
A panelboard is one of the most important electrical devices that should be found in every establishment.
What is a large single panel, frame, or assembly of panels used for?
For larger-scale buildings or sites, a large single panel, frame, or assembly of panels can be used for mounting the overcurrent switches and protective devices, buses, and other equipment. These floor-mounted, freestanding solutions are known as switchboards.
