The Lighting DB typically includes a set of main switchgear, such as circuit breakers or fuses, that can be used to control the flow of electricity to the lighting circuits. It also includes metering devices, such as ammeters and voltmeters, that can be used to monitor the electrical usage and identify any potential issues.
The Lighting DB also includes a set of protection devices, such as overcurrent protection, earth-fault protection, and residual current protection, that are designed to protect the electrical system and equipment from damage in case of faults or overloads.
The Lighting DB also includes a control system that monitors the status of the electrical system, and can be used to turn power on and off to different parts of the building as needed. The control system can also provide alarms and status indications to the operator.
In summary, Lighting Distribution Board (DB) is an electrical device used to control and distribute electrical power to lighting fixtures in a building or facility. It typically includes a set of main switchgear, metering devices, protection devices and a control system to monitor the status of the electrical system, turn power on and off as needed, and provide alarms and status indications to the operator.
