Abstract: Provided is a distribution panel. The distribution panel includes a main busbar compartment in which a main busbar is provided and which is provided as an independent space and an arc duct provided at a rear side of the main busbar compartment to discharge an arc generated in the main busbar compartment. The main busbar compartment includes a communication hole defied in one surface of the main busbar to allow the main busbar compartment to communicate with the arc duct and a relief device rotatably provided on one side of the communication hole to open or close the communication hole. The relief device is bendable in multi stages. Thus, the arc may be effectively discharged while reducing a size of the distribution panel.

Abstract: A switchboard applied with a bushing-type current transformer includes a terminal bushing inserted from a front direction, a switchboard terminal coupled to the terminal bushing, a metering current transformer bushing inserted from a front direction and inserted into the terminal bushing while wrapping the switchboard terminal, and a metering current transformer disposed outside the metering current transformer bushing and assembled or disassembled at a front surface through a circuit breaker chamber. Thus, the switchboard applied with a bushing-type current transformer has an advantage of having a high degree of internal space utilization or capable of being made to be compact.
