What is a fixed distribution box called

A fixed distribution box is commonly called a distribution board, panelboard, switchboard, or remote power panel (RPP).

A fixed distribution box is a permanently installed electrical panel that safely distributes incoming power from a utility or UPS to multiple branch circuits within a building or industrial facility. It houses essential components such as circuit breakers, fuses, busbars, residual current devices, and switches, which protect circuits from overloads, short circuits, and electrical faults while organizing power distribution efficiently .

Common Names and Variants

• Distribution Board / Panelboard: The most widely used term for a fixed unit that divides electrical power into smaller circuits, typically mounted on a wall in homes, offices, or industrial buildings .
• Switchboard: Often used in industrial or high-capacity settings, it includes busbars, selective protection schemes, and metering for large-scale power distribution .
• Remote Power Panel (RPP): A fixed panel that extends power distribution from a main switchgear to branch circuits, commonly used in data centers or industrial lines .
• Breaker Panel / Electric Panel: Alternative terms emphasizing the inclusion of circuit breakers for safety and control .

Key Features

• Permanent Installation: Unlike portable distribution boxes, fixed units are integrated into the building's electrical system with proper fault duty, labeling, and service clearances .
• High Capacity: Supports multiple circuits and higher power loads, including single-phase and three-phase systems.
• Safety and Maintenance: Provides organized access for maintenance, integrates surge protection, and allows for future expansion . In summary, a fixed distribution box is a central hub for electrical power management, and depending on context, it may be referred to as a distribution board, panelboard, switchboard, or RPP, all of which serve to safely distribute and protect electrical circuits within a building or industrial setup .
