PROBLEM TO BE SOLVED: To make the maintenance and inspections of a panelboard easier by constituting a ground relay terminal, in such a way that the terminal is installed in or attached to the case of a panelboard and has a plurality of terminals and name writing sections near the terminals. SOLUTION: A panelboard is provided with a case 31 attached to a wall surface and a panel detachably attached to the front face of the case 31 and a master mount and branch mounts are mounted in the case 31. In addition, a ground relay terminal 1 is attached to the edge section of the bottom face of the case 31 and a plurality of terminals 2 for connecting grounding cable are provided on the terminal 1. Moreover, name writing sections 3 are provided at the positions corresponding to the terminals 2 in the section of the case 31 in which the ground relay terminals 1 are attached. Therefore, the maintenance and inspections of a panelboard become easier in such a way that the labor and time required for searching the connecting sources of the grounding cables connected to the terminals by tracing the grounding cables can be eliminated, etc., because the name of the connecting source of the grounding cable connected to each terminal 2 can be recognized at a glance from the name writing section of each terminal 2. |
