The U.S. National Electrical Code (NEC) defines a switchboard as "a large single panel, frame, or assembly of panels on which are mounted, on the face, back, or both, switches, over-current and other protective devices, buses, and usually instruments".
Low-voltage switchboards are the most common type. You'll see them in homes, office buildings, small shops, and light industrial settings. These systems usually run at 120V, 240V, or 480V, depending on the application. They're easier to work with, take up less space, and are simpler to install and maintain.
Electrical systems would be prone to overload, short circuits, and other potentially hazardous conditions without switchboards. Switchboards also facilitate the isolation of faulty circuits, allowing for targeted repairs and minimizing downtime. Their role in distributing power efficiently helps optimize energy usage and reduce operational costs.
Bulb Holders – Used for attaching light bulbs to the switchboard system. Wiring – Includes live, neutral, and earth wires for power distribution. Circuit Breakers – Protect the system from overloads and short circuits. Busbars – Conduct electricity within the switchboard and distribute it efficiently.
Choosing the right switchboard is key to ensuring your electrical system works efficiently and safely. We''ve covered the main types of switchboards, their functions, and important factors like
