All Your Questions

Here are some frequently asked questions about TOSUNlux Panel Board

A panelboard is a crucial component of an electrical distribution system used to safely distribute electricity throughout commercial and industrial facilities. It divides an electrical power feed into branch circuits, providing a protective circuit breaker or fuse for each circuit within a common enclosure. Panelboards protect branch circuits from overloads and short circuits, meeting UL 67 and NEMA Standard PB1 requirements. They are typically flush or surface mounted and have a maximum incoming current of 1,200 A. Panelboards are similar to switchboards but have differences in design and functionality.

Electrical Panels:
Also known as load centers, these panels distribute electricity throughout homes or buildings, protecting circuits and managing power flow.
Solar LT Panels:
These panels receive power from solar panels and distribute it to different areas, commonly used in industries for internal and external applications.
Power Control Center (PCC Panel):
Controls electricity distribution with components like air circuit breakers and MCCBs, ensuring proper power management.
Motor Control Center (MCC Panel):
Manages multiple electric motors in commercial and industrial settings, offering control through starters like DOL or star-delta starters
Automation Panel (SCADA PLC Panel):
Utilizes PLC logic for automation in various electronic and electrical circuits, enhancing control and monitoring capabilities.

The primary differentiation between a distribution board and a panel board lies in their functions and placements within an electrical system:
Distribution Board:
A distribution board, also known as a circuit breaker panel, serves as the centralized location for housing all the circuits within a building or facility. Typically found in areas such as garages, it acts as the central hub where various branch circuits for lighting, appliances, and outlets are managed.
Panel Board:
In contrast, a panel board is an electrical panel designed to segregate an electrical power supply into branch circuits, with protective circuit breakers or fuses incorporated for each circuit. Engineered to adhere to specific standards like UL 67 and NEMA Standard PB1, panel boards are frequently utilized in commercial and industrial settings.

waterproof panel board Application

Waterproof panel boards, also referred to as water-resistant panel boards, are specialized electrical enclosures engineered to endure exposure to moisture, water, and severe environmental conditions. Equipped with protective features, these panels shield internal electrical components from water damage, rendering them ideal for outdoor and humid environments.

Ideal for outdoor entertainment areas, waterproof panel boards offer a safe and weather-resistant solution for powering lighting, audio systems, and other electrical amenities in patios, decks, or garden spaces.

In agricultural settings, waterproof panel boards are invaluable for providing weather-resistant electrical distribution on farms. Whether supporting irrigation systems, powering machinery, or managing lighting in barns, these boards offer reliable protection against the challenges of outdoor agricultural environments.

Waterproof panel boards find application in industrial settings with rigorous cleanliness standards, such as food processing plants or pharmaceutical facilities. Their ability to resist water ingress ensures the integrity of electrical systems in washdown areas, where equipment is regularly cleaned with water or other sanitizing agents.

What Are the Advantages of Using Different Types of Panel Boards

The Advantages of Using Panel Boards

Selective Tripping: Panel boards facilitate selective tripping of breakers, allowing for the targeted isolation and shutdown of specific faulting branch circuits without disrupting the entire system. This capability proves invaluable in environments such as manufacturing plants or data centers, where minimizing equipment downtime is paramount to maintaining production efficiency.

Personnel Safety: Panel boards play a pivotal role in safeguarding personnel by promptly shutting down electricity during instances of overloads or short circuits. Modern advancements, such as the integration of arc fault circuit interrupters into circuit breakers, further enhance protection against arc faults, mitigating the risk of injuries resulting from electrical incidents.

Protection Against Arcing Faults: Certain panel boards are engineered to withstand and contain explosions, providing an additional layer of safety in the event of critical faults. This feature is instrumental in shielding facilities and individuals from the hazards associated with arcing faults and arc blasts.

Enhanced Safety Features: With ongoing advancements in circuit breaker technology, panel boards now boast enhanced safety features like arc fault protection and explosion containment, fostering a safer electrical environment for both employees and facilities alike.

Critical Role in Electrical Systems: Panel boards, alongside other components of modern electrical distribution systems, are indispensable for sustaining operations across residential, commercial, industrial settings, and infrastructure systems. Serving as a cornerstone element, they ensure continuous and dependable electricity distribution while upholding stringent safety protocols.

Cost-Effectiveness: The judicious selection of panel boards based on specific requirements can yield significant cost savings. For instance, opting for main lug only (MLO) panel boards where permissible instead of main circuit breaker (MCB) panel boards can substantially reduce construction expenses while meeting essential electrical standards.

These advantages underscore the importance of selecting the appropriate type of panel board tailored to meet distinct needs while prioritizing safety, efficiency, and cost-effectiveness within electrical systems.
