The wiring work can be easily performed in a state in which a plurality of distribution boards are arranged side by side, without the electric wire conductor in the duct becoming an obstacle. Also, the side plates of the upper and lower frames are attached to the back plate.
The fixed piece to be fixed and the duct surface from both ends of the fixed piece
Two vertical pieces extending in the front direction, and the two vertical pieces
And a support piece for connecting the pieces and supporting the front plate, and
As a frame with an opening through which the connected connection conductor can be inserted
Attach the side plate that is the frame as it is during assembly
In this way, an opening for connecting conductor insertion can be
There is no need to open holes in the side plates for conductor insertion.
The opening for inserting the connecting conductor can be easily formed
You. In particular, place the two vertical pieces of the side plate in front of the duct surface
Since it extends in the direction, the supporting piece supports the front piece
The upper and lower openings of the upper and lower frames and the side plate side for connecting conductor insertion
The opening can be enlarged and the connection conductor can be inserted
Work becomes easy.
