しやすいという不便もあつた。[Detailed explanation of the invention] The voltage of the branch circuit of a single-phase three-wire distribution board is usually
If the device uses 100V, but the load is 200V, check the voltage of the branch circuit to which the load is connected.
It is necessary to change to 200V, so conventionally,
For example, if you are trying to change a branch circuit that receives 100V at the _L1 and N poles to 200V, the _L1 pole side of the connection piece that connects the power side terminal of the branch breaker of the branch circuit and the copper bus bar will be You will need to remove the connection piece that connects the copper bus bar on the N pole side and the branch breaker terminal, and replace it with the new connection piece that connects the copper bus bar on the L ₂ pole side and the branch breaker terminal. It was hot. Therefore, there are two connection pieces, one for 100V and one for 200V.
This required double the mold and parts costs, and the manufacturer of the distribution board had to include the 200V connection piece as an accessory inside the board, which was a hassle. Furthermore, when installing the distribution board, a 100V branch circuit should also be installed in case the resident later installs 200V equipment.
The 200V connection piece had to be saved even after the installation work, and if it was used as an accessory like in the past, it would be inconvenient because it would easily get lost.

端８の段差はＸとなる。 Figure 3 shows the branch breaker 1 changed to 200V, and the L _2- pole copper bus 4 and the terminal 14 of the branch breaker 1.
Leave the connections as they are, and connect the screw end 8 provided on the L _1- pole copper bus 2 as shown in Figure 2 and the terminal 15 of the branch breaker 1 with the connection piece 5 shown in Figure 4, which is the same as for 100V.
However, since the terminal 15 and the N-pole copper bus 3 are at the same height, and the N-pole copper bus 3 and the L _1- pole copper bus 2 have a height difference of X, the terminal 15 and the screw end The level difference of 8 is X.

つてネジ６によつて接続することができる。 Here, as shown in FIG. 4, the connecting piece 5 has a leg piece 10 with a step of X, which is the same as the above-mentioned step, from the middle part of the leg piece 9 in a direction perpendicular to the leg piece 9.
When the leg piece 10 of the connecting piece 5 is connected to the terminal 15 of the branch breaker 1 as shown in FIG.
2 and the screw ends 8 of the _L1 pole copper bus 2 have the same height and can be connected by the screw 6.

以上の様に構成された分岐ブレーカの電圧切換

のみで良いから、電圧変更用の部品を粉失するこ
とがないという効果を有する。 The branch breaker voltage switching device configured as described above only requires one type of connection piece to connect the branch breaker terminal and the copper bus bar, and is capable of switching between 100V and 200V as before.
Compared to manufacturing dedicated connection pieces for each, mold costs are lower.
Saves parts cost and number of parts, and is 200V
There is no need to use a connecting piece as an accessory, and when dealing with voltage changes in branch circuits after installing a distribution board, you only need to change the mounting position of the parts that are already connected. This has the effect of not causing parts to be lost.
