BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution panel, and more particularly, to a distribution panel that can easily perform wiring work for branching a plurality of contacts from an N-phase power source among three-phase AC power sources input to the distribution panel.

Auxiliary bus bar 24 for providing a contact.

Meanwhile, the bus bar 21 connected to the R phase, the S phase, and the T phase of the main power circuit breaker 11 may be cut to fit the length from the main power circuit breaker 11 to the busbar support 14, but may be N phase. The bus bar 22 connected to the bus bar is cut and used to have a length longer than the length from the main power circuit breaker 11 to the bus bar support 14. This is to couple the N-phase bus bar 22 to protrude from the busbar support 14 and to electrically connect the auxiliary bus bar 24 for extracting a plurality of N-phase power to one end thereof.

In addition, one end of the auxiliary bus bar 24 is electrically connected to the N-phase bus bar 22, and the other end is supported by the support 15 attached to the base panel (not shown) of the distribution panel. In general, the busbar support 14 and the support 15 are manufactured at the same height, and thus, if one end of the auxiliary bus bar 24 is not bent stepwise, the auxiliary bus bar 24 and the N phase are made in accordance with the height of the support 15.

As described above, in the conventional distribution panel, the length of the bus bar 22 connected to the N phase for coupling with the auxiliary bus bar 24 is the bus bar 21 connected to the R, S, and T phases. It should be longer than the length of. Therefore, regardless of phase, the length of the busbar busbar cannot be equalized, and there is a problem in that the N-phase busbarbar must be managed separately.

In addition, in order to combine the N-phase busbar and the auxiliary busbar using a conventional busbar support, a through hole must be separately formed at the extended end of the N-phase busbar, and at the extended end of the N-phase busbar One end of the auxiliary bus bar to be combined had to be bent stepwise. Since the additional hole work and bending work must be performed, the time required for manufacturing the entire distribution panel is delayed, and the production efficiency is also lowered.

The present invention has been made to solve the above problems, by providing an N-phase branch fastening portion separately from the N-phase fastening portion in the busbar support by electrically connecting the N-phase fastening portion and the N-phase branch fastening portion, when manufacturing the distribution panel An object of the present invention is to provide a distribution panel having an improved structure to facilitate wiring work for branching a plurality of contacts from an N-phase power source.
