D-B Panel Board (Distribution Board) inspection is essential in Bangladesh, as it is a vital component of the power distribution system. Regular inspection and testing of the D-B Panel Board are required to ensure its proper functioning and protection from any electrical faults or hazards. This inspection checks the correctness and functionality of the circuit breakers, fuses, cable connections, and other components of the panel board. In addition, the voltage, current, and performance of electrical protection devices are monitored. Various power supply companies and engineering service companies in Bangladesh conduct these inspections regularly, which helps ensure the safety and stability of the power distribution system.
