In addition to the usual electrical equipment installation procedures, the installation method should also pay attention to the following points: 1. The installation of the leakage protector should meet the requirements of the manufacturer's product manual. 2. The leakage protector marked on the power supply side and the load side shall not be reversed. If it is reversed, it will cause the tripping coil of the electronic leakage protector to be disconnected from the power supply and be powered off, so that it will be burned for a long time. 3. Install the leakage protector. Do not remove or abandon the original safety protection measures. The leakage protector can only be used as an additional protection measure in the electrical safety protection system. 4. When installing the leakage protector, the neutral line and the protection line must be strictly distinguished. When using a three-pole four-wire and four-pole four-wire leakage protector, the neutral line should be connected to the leakage protector. The neutral line passing through the leakage protector shall not be used as a protective line. 5. The working zero line must not be grounded repeatedly on the load side of the leakage protector, otherwise the leakage protector will not work normally. 6. The branch of the leakage protector is used, and the working zero line can only be used as the neutral line of the circuit. It is forbidden to connect with the other working line of the circuit. Other lines or equipment cannot borrow the line or equipment after the leakage protector has been used. Work zero line. 7. After the installation is completed, the leakage protection of the completed work shall be carried out in accordance with the provisions of 3.1.6 of the Code for Acceptance of Construction Electrical Engineering Construction (GB50303-2002), that is, the requirements for the “Dynamic Action Test for Leakage Protectors for Power and Lighting Projectsâ€. The test is carried out to ensure its sensitivity and reliability. During the test, the test button can be operated three times, and the load is divided into three times to confirm that the action is correct before it can be officially put into use. The safe operation of the leakage protector is guaranteed by a set of effective management systems and measures. In addition to regular maintenance, the operating characteristics of the leakage protector (including the leakage action value and the operating time, the leakage current value, etc.) should be tested regularly, and the test record should be made and compared with the initial value of the installation. Compare and judge whether the quality has changed. In use, use the leakage protector according to the requirements of the instruction manual, and check it once a month according to the regulations, that is, operate the test button of the leakage protector to check whether it can normally disconnect the power supply. During the inspection, it should be noted that the time for operating the test button should not be too long. Generally, it is better to use jog, and the number of times should not be too much, so as not to burn internal components. The leakage protector trips during use. If the switch does not find the cause of the switch action, the test is allowed to send power once. If it trips again, the cause should be identified, the fault should be found, and the power must not be continuously forced. If the leakage protector cannot be used, it should be inspected or replaced by a professional electrician immediately. If the leakage protector malfunctions and rejects, the cause is caused by the leakage protector itself, and on the other hand, the reason from the line should be carefully analyzed. Do not disassemble and adjust the internal components of the leakage protector.
