PROBLEM TO BE SOLVED: To easily carry out the connecting work of grounding cables in a short time by constituting a ground relay terminal in such a way that the terminal is not fixed in a panelboard, but housed in the panelboard in a state where the terminal is only supported by connected grounding cables. SOLUTION: A panelboard is provided with a case 31 attached to a wall surface and a panel 32 detachably attached to the front face of the case 31 and a master circuit breaker 34 and a plurality of branch circuit breakers 35 are attached to the case 31 in a state where the breakers 34 and 35 are respectively attached to a master mount 36 and a plurality of branch mounts 37. A plurality of grounding cables 21 drawn in the panelboard through wiring holes 33 is connected to a ground repeating terminal 1 and the terminal 1 is not fixed in the panelboard, but housed in the panelboard in a state where the terminal 1 is only supported by the connected grounding cables 21. Therefore, the connecting work of the grounding cables can be carried out easily in a short time, because the terminal 1 can be moved freely and the connecting work can be conducted at the positions to which the cables 21 are drawn in the panelboard. |
