Because the conventional method is connected to one main body, even if the earth leakage circuit breaker is one or each of the outlet insertion hole separately, there is a problem in use.

The present invention relates to a multi-type outlet with an earth leakage breaker (1) attached to the earth leakage breaker (1) is inserted into the outlet in the same technical field, or can connect several plugs (5) to one outlet Although the earth leakage breaker (1) using the bimetal or shape memory alloy (7) of the compact and simple method is attached to the outlet, when the earth leakage breaker (1) is operated, the power of the outlet is cut off together. Not only the device connected to the plug that has a problem can not be used, but other connected devices also have a disadvantage in that the power is cut off.

In addition, the multi-type outlet applied in the present invention is connected to the main power panel only when a problem occurs in one place, in which only one outlet (2) is connected to the power line (4) without the current leakage circuit breaker (1). The circuit breaker (3) is operated to turn off the power has the disadvantage that all the power is cut off.

The present invention is to connect a plurality of outlets (2) to a single power line (4), each at a specific interval, to connect the earth leakage breaker (1) one by one to each outlet (2) to use as a multi-type power cable It is used to make a power connection device that can connect various devices or work lights (13) from the power line (4) of the power outlet (4). Before the main circuit breaker 3 operates, the circuit breaker 1 connected to the outlet 2 in question is first operated to cut off the power.

If you use the multi-wall outlet (2) with the earth leakage breaker (1) connected as in the above configuration, even if a problem occurs in one or many outlets connected to the power cable, Operate only the breaker (1) to cut off the power to the outlet in question (2), and do not affect the earth leakage breaker (1) connected to the other outlet (2) connected together and operate the main earth leakage breaker (3) on the main power panel. Before powering off the outlet (2) in question.

The present invention relates to a multi-type outlet with an earth leakage breaker, and in the same technical field, a small and simple method is formed by inserting an earth leakage breaker into an outlet or connecting one plug to a single outlet. A device connected to a plug having a problem because the earth leakage breaker (1) using bimetal or shape memory alloy (7) is attached, but when the attached earth leakage breaker (1) operates, the power of the outlet is all cut off together. Not only can not use, but other connected devices also had a disadvantage that can not be used because the power is cut off.

In order to use multiple power cables connected in parallel by placing several outlets on one power cable at specific intervals, the circuit breaker is connected to each outlet one by one to connect various devices or lamps. If a fault occurs in one outlet (2), it may be used to create a power connection that can be connected to the ground fault breaker (2) connected to the outlet (2) in question before the mains breaker (3) 1) is configured to operate first and cut off the power in advance.

When using a multi-wall outlet (2) with a grounded circuit breaker (1) connected as in the above configuration, even if a problem occurs in one or a plurality of outlets (2) connected to the power line (4) Only the ground fault breaker (1) connected to the outlet (2) in which the power supply is operated cuts power to the outlet (2) in question, and does not affect the ground fault breaker (1) connected to the other outlet (2) connected together. Before the main circuit breaker 3 operates, the power of the outlet 2 in question is cut off.

The earth leakage circuit breaker 1 used in the present invention is heat-produced in the bimetal or shape memory alloy 7 as shown in FIG. 5 when a short circuit or short circuit occurs by using a bimetal or a shape memory alloy 7 which is already commercially available. It is designed to bend in the opposite direction, so the contact point 9 is turned off. It is an earth leakage circuit breaker that can be easily attached or inserted into the device. It is small and simple in structure and low in cost. It can be replaced.
