Understanding Panelboard: Types, Benefits, and Applications
Panelboard is a type of electrical wiring board used in buildings for distributing power and lighting circuits. It consists of a series of metal breaker switches, fuses or circuit protectors that are mounted on a wooden or plastic base. The breaker switches or fuses are connected to the main electrical panel and are used to control the flow of electricity to different parts of the building.
Panelboard is commonly used in commercial and industrial buildings where there are multiple circuits that need to be controlled and protected. It is also used in residential buildings, especially in older homes where the electrical system has been upgraded or expanded.
There are several types of panelboard available, including:
1. Main panelboard: This is the primary panelboard that controls the entire electrical system of a building. It is usually located in the basement or a utility room and contains all the main breaker switches and fuses.
2. Sub-panelboard: This is a smaller panelboard that is used to distribute power and lighting circuits to specific areas of a building. It is typically located in a remote location, such as a garage or laundry room.
3. Distribution panelboard: This is a type of panelboard that is used to distribute power to multiple circuits. It is commonly used in commercial and industrial buildings where there are many electrical devices that need to be powered.
4. Motor control panelboard: This is a specialized type of panelboard that is used to control the speed and direction of motors in industrial applications.
5. Lighting panelboard: This is a type of panelboard that is specifically designed for controlling lighting circuits. It typically contains a series of breaker switches or fuses that are connected to the lighting fixtures.
Panelboard provides several benefits, including:
1. Increased safety: By using panelboard, electrical systems can be better protected from overloads and short circuits, which can cause fires and electrical shocks.
2. Improved efficiency: Panelboard allows for easier management of electrical circuits, which can lead to improved efficiency and reduced energy costs.
3. Flexibility: Panelboard can be customized to meet the specific needs of a building, allowing for greater flexibility in terms of circuit layout and control.
4. Reduced labor costs: By using panelboard, electricians can more easily install and maintain electrical systems, reducing labor costs and downtime.
5. Improved reliability: Panelboard can help to improve the reliability of an electrical system by providing a centralized location for breaker switches and fuses, which can reduce the risk of failures and outages.
