Further, with the attachment member 55 screwed to the mounting substrate 58,
Sealing hole 55b at the top of the attachment member 55 and the sealing cover 3
The ring-shaped projection 34 provided in 1 is sealed with, for example, an endless linear body, and the mounting member 55 is prevented from rotating, so that the sealing member 51 cannot be removed, thereby inputting the switch 7 for emergency equipment. The disconnection between the side 7a and the feed line 8 is disabled. In addition, the output side 7b of the switch 7 for emergency equipment
Also in the above, since the upper side of the output terminal is covered by the upper surface cover 53b, the line conductor (power supply side line,
The disconnection with the ground side line 90 is also disabled.

Therefore, the feed line 8 for supplying electricity to the emergency equipment switch 7 is connected between the output side 3b of the current limiter 3 and the input side 4a of the master switch 4 as in the conventional case. Since it is connected to the input side 3a of the current limiter 3, even if a current exceeding the contract current flows and the current limiter 3 is forcibly opened, the current is limited via the feed line 8. Electricity can be supplied to the emergency equipment switch 7 regardless of the opening operation of the current limiter 3. In addition, the input terminal and the output terminal of the emergency equipment switch 7 are combined into one sealing member 51.
When the feed line 8 serving as a power line to the emergency equipment switch 7 is connected to the input terminal of the current limiter 3 and the input terminal of the emergency equipment switch 7 by simultaneously sealing with It is possible to make processing difficult on the input side 3a of the current limiter 3 and the input side 7a of the emergency equipment switch 7, respectively. That is, the upper cover 53a of the sealing member 51 closes the upper side of the input terminal of the emergency load, and the upper cover 53b closes the upper side of the output terminal of the emergency load. The connection with the line 8 cannot be released, and the connection between the output side 7b of the emergency equipment switch 7 and the line conductor 90 on the emergency load side is also disabled. In addition, the midway portion of the feed line 8 is closed by the cover member 9a, and the connecting portion between the input side 3a of the current limiter 3 and the feed line 6 is also sealed by the sealing member 30.
Since the disconnection of the feed line 8 is also impossible on the input side 3a of the above, as a result, the coating cannot be peeled off from the entire feed line 8 and the machining of the entire feed line 8 can be prevented. As a result, it is possible to prevent the feed line 8 from being connected to the branch switch 6 for general home appliances that is different from the switch 7 for emergency equipment, so that a current exceeding the contract current flows from the power supply for general home appliances. Sometimes the current limiter 3 operates normally.

Further, since the sealing member 51 has a function of sealing both the input terminal and the output terminal of the emergency equipment switch 7 at the same time, the sealing work is facilitated and the sealing member 51 and the emergency equipment opening / closing are performed. Since the container 7 and the container 7 are attached to the box body 2 by the same attachment member 55, the sealing (attachment) work of the sealing member 51 is facilitated, and the workability is further improved.

Further, in this embodiment, a plurality of branch switches 6 are provided.
One of the switches is electrically disconnected from the branch bar 5, the feed line 8 is connected to the input side of the switch which is not connected to the branch bar 5, and the output side 7b is connected to the emergency side. Since the emergency equipment switch 7 is configured by connecting the emergency load, it is not necessary to provide a special space for arranging the emergency equipment switch 7, which contributes to downsizing of the distribution board. There are also advantages.

In the present embodiment, a small piece plate-shaped first sealing member 51a that seals the input terminal of the emergency equipment switch 7 and a small piece plate-shaped second sealing member that seals the output terminal of the emergency equipment switch 7. 51
b and the sealing members 51a, 51
The same attachment member 55, 55 can be attached to the inside of the box 2 for each b. Further, the emergency equipment switch 7 is mounted on a mounting board 58 arranged at a position different from the branch switch 6. Reference numeral 80 in FIG. 5 denotes a mounting board for the current limiter 3. Other configurations are similar to those of the embodiment shown in FIGS. In this embodiment, the first and second sealing members 5
1a and 52b are large enough to cover the upper surface of the convex step 7c of the emergency equipment switch 7, and the input side 7a of the emergency equipment switch 7 is a first sealing member 51a. ,
By separately sealing the output side 7b with the second sealing member 51b, similarly to the above embodiment, the feed line 8 serving as a power supply line to the emergency equipment switch 7 is connected to the input terminal of the current limiter 3 and the emergency equipment. When connected to the input terminal of the switch 7 for emergency use, it becomes difficult to process the feed line 8 on the input side 3a of the current limiter 3 and the input side 7a of the switch 7 for emergency equipment, respectively. When the current flows, the current limiter 3 can operate normally. Further, the first and second sealing members 51a and 51b can be attached together with the emergency equipment switch 7 to the mounting substrate 58 in the box body 2 by the same attaching member 55, respectively. , 51b can be easily sealed (attached), workability is improved, and since the sealing member 51 is formed in a small piece plate shape, the material cost of the sealing member 51 can be reduced. .

The length L ₁ of the sealing member 51 is formed to be larger than the length L of the switch 7 for emergency use, whereby a line conductor (feed line 8) connected to at least one of the input terminal and the output terminal of the switch 7 for emergency equipment. , The core wire portion 90a of the wire conductor 90) is provided to isolate the core wire portion 90a. For example, the core wire portion in which the coating of the wire conductor 90 is peeled off from the convex step portion 7c of the switch 7 for emergency equipment. When 90a is exposed, the core wire portion 90a can be isolated by the isolation piece 50, so that the emergency equipment switch 7 and other switches or wire conductors are input terminals or outputs of the emergency equipment switch 7. It may be difficult to make contact with any of the terminals Come, it is possible to improve the insulation of the emergency equipment switching device 7.

As a modification of FIG. 7, for example, first and second sealing members 51, which are substantially the same as those of the embodiments of FIGS. 5 and 6, are provided.
