Description

  The present invention relates to a mounting structure for a conductive part protective cover for protecting a conductive part of a distribution board.

  For the purpose of preventing electric shock accidents when opening the distribution board door and performing wiring work etc., a structure is widely adopted in which a protective cover is provided on the conductive part such as a bus bar connected to the terminal part of the main breaker ( For example, Patent Document 1).

  The protective cover described in Patent Literature 1 is placed on the bar holder that supports the bus bar, the terminal portion of the main breaker, the screw hole formed in the protective cover, and the bar holder and the upper end of the terminal portion, respectively. The formed screw holes are aligned and fixed with screws.

  However, the protective cover described in Patent Document 1 covers only the front surface of the conductive portion (the door direction of the distribution board body) (hereinafter referred to as the front cover). If it is necessary to cover the side surface, install a side cover mounting member on the distribution board board to install the side cover, or attach it to the existing front cover. Instead, it is necessary to newly produce a protective cover having an L-shaped cross section or a U-shape that can be integrally covered from the front side to the side surface, and there is a problem that additional installation of the side surface cover takes time.
