る。When a primary electric wire having a capacity equal to or larger than the capacity of the first main breaker is connected to a primary terminal of the first main breaker, the primary electric wire is thick and a crimp attached to a tip of the primary electric wire is used. Because the terminal is large, it may not be possible to connect to the primary terminal of the main breaker. In this case, the primary feed terminal block (1) described in Utility Model Registration No. 2545117 is used. The primary feed terminal block (1) has a screw insertion hole (3a) facing the primary terminal screw hole (5a) of the primary terminal of the first main breaker (5), and a primary feed terminal screw hole (3c). ) And an input terminal hole (3
b) a plurality of terminal seats (3),
(3), a base (2) provided with a partition wall at both ends of (3), and the screw insertion hole (3a) of the terminal seat (3) is connected to the primary terminal screw of the first main switch (5). It is screwed and fixed to the hole (5a) with a primary terminal screw (4e). Then, one end of the primary feed wire (8) is connected to the primary feed terminal screw hole (3).
c) is screwed and fixed with the primary feed terminal screw (4a),
The other end is the primary terminal (6a) of the second main breaker (6).
Are screwed and fixed with primary terminal screws (4c). The primary electric wire (7) is screwed and fixed to the input terminal hole (3b) with the input terminal screw (4b). Since the space between the partition walls of the base (2) is wide, even if the crimp terminal (7a) attached to the primary electric wire (7) is large, it can be connected.

あった。However, when the main distribution circuit is branched into two main breakers 61 and 62 in the same distribution board, the main breakers 61 and 62 are shipped when the distribution board is shipped.
Although the primary feeder 63 is not connected between the primary feeder 63 and the primary feeder 63, the primary feeder 63 is not connected to the distribution board. The primary feeder 63 connected to the primary feeder 61 must be once removed and the primary feeder 63 and the primary side electrical wire 66 must be connected, and there is a disadvantage that workability is poor. Further, when the primary feed wire 63 and the primary wire 66 are connected to the first main breaker 61 at the same time, the crimp terminals of the two wires rub against each other and the terminal screw 65 is loosened.
