Claims

[Scope of utility model registration request]

By inserting a plug-shaped test terminal into the terminal connection part provided on the panel surface of the power distribution board, the performance of various devices attached to the panel surface can be freely tested. At the connection part, there are two
In addition to providing two terminals and a first main contact electrically connected to the terminals, two terminals are provided to connect devices other than the device under test and the current transformer to configure the circuit into an independent closed circuit. A terminal and a second main contact electrically connected to the terminal are provided, and the first main contact and the second main contact of each of the closed circuits are operated to open during driving operation to connect the double open circuits in series. A plug-shaped terminal having a conductive part for connecting the current transformer with the other equipment is detachably provided, and the plug-shaped terminal is pulled out and moved to a position where the engagement with the second main contact is released. A test terminal for a power distribution board, characterized in that the connection circuit of only the device under test can be separated and taken out to the outside while the connection circuit with the device under test is closed. .
