400 amp 3 phase main breaker panel

A 400 amp 3-phase main breaker panel is a type of electrical panel that is designed to distribute power to a commercial or industrial facility. Here are some key features and considerations:

Key Features:

• 400 amps: The panel has a maximum capacity of 400 amps, which is suitable for larger commercial or industrial applications.
• 3-phase: The panel is designed to handle 3-phase power, which is commonly used in commercial and industrial settings.
• Main breaker: The panel has a main breaker that can be used to disconnect power to the entire panel in case of an emergency.
• Busbars: The panel has busbars that connect the main breaker to the individual circuit breakers.
• Circuit breakers: The panel typically has multiple circuit breakers that can be used to control individual circuits or groups of circuits.
• Grounding: The panel has a grounding system that provides a safe path to ground for fault currents.

Considerations:

• Size: The panel is typically larger than a residential panel, with a larger footprint and higher height.
• Weight: The panel is heavier due to the larger size and the weight of the busbars and circuit breakers.
• Installation: The panel requires a more complex installation process due to the larger size and the need to connect multiple busbars and circuit breakers.
• Cost: The panel is more expensive than a residential panel due to the larger size and the higher capacity.
• Maintenance: The panel requires more frequent maintenance due to the larger size and the need to check and maintain the busbars and circuit breakers.

Common Applications:

• Commercial buildings: Office buildings, retail stores, restaurants, and other commercial facilities that require a higher power capacity.
• Industrial facilities: Manufacturing plants, warehouses, and other industrial facilities that require a higher power capacity.
• Data centers: Data centers and other high-density computing facilities that require a high power capacity and reliability.
• Healthcare facilities: Hospitals, clinics, and other healthcare facilities that require a high power capacity and reliability.

Benefits:

• Higher power capacity: The panel can handle a higher power capacity than a residential panel, making it suitable for larger commercial or industrial applications.
• Reliability: The panel is designed to provide reliable power to the facility, with features such as busbars and circuit breakers that can handle high currents and fault currents.
• Flexibility: The panel can be customized to meet the specific needs of the facility, with options such as additional circuit breakers and busbars.
• Cost-effective: The panel can be more cost-effective than installing multiple smaller panels, especially for larger facilities.
