<p>PROBLEM TO BE SOLVED: To provide a power distribution panel which is capable of assuring high safety for testing of fixed terminals in a main circuit. SOLUTION: In a distribution panel equipped with a shutter device between fixed terminals 2 of a main circuit which is provided in a distribution panel frame and a main circuit plug 31 provided in an electrical equipment unit 3, a shutter lock mechanism 5 is provided which is capable of giving an open maintenance state to a shutter device 4, when the shutter 41 is artificially set to an open state and is capable of canceling the open maintenance state of the shutter device, when the electrical equipment unit 3 has been installed to the distribution panel frame 1. Thus, the open state between the fixed terminal 2 of the main circuit and the main circuit plug 31 can be surely maintained by artificially pushing down the shutter 41, after the shutter 41 has been set to a shielded state.</p> |
