When installing the Chint NEX5-C10600 household distribution box, strict standard operations are required in multiple aspects, from preliminary planning and installation operations to post-installation inspections, to ensure electrical safety and the normal operation of equipment. The specific precautions are as follows:  

I. Preparation and Planning Before Installation**  

1. **Confirm the Installation Environment**  

   - **Location Selection**  

     - Install in a dry, ventilated place without corrosive gases, and avoid areas near water sources (e.g., kitchens, bathrooms) or high-temperature zones (e.g., heating pipes, gas stoves) to prevent the box from being damp or components from overheating.  

   - **Height Specification**  

     - For recessed installation, the lower edge of the distribution box is recommended to be 1.5-1.8 meters from the ground, which is convenient for daily operation and maintenance and complies with household electrical safety codes.  

   - **Space Reservation**  

     - Ensure sufficient space behind and around the distribution box to avoid conflicts with obstacles such as wall steel bars, water pipes, and gas pipes, and reserve at least 10cm of maintenance space.  

2. **Circuit Design Planning**  

   - **Circuit Distribution**  

     - Reasonably distribute the 6 circuits according to household electricity needs. For example:  

       - 2 lighting circuits (living room + bedroom, kitchen + bathroom);  

       - 2 socket circuits (living room sockets, bedroom sockets);  

       - 1 dedicated air conditioner circuit (high-power air conditioners);  

       - 1 dedicated kitchen/bathroom circuit (refrigerators, water heaters, etc.).  

   - **Load Calculation**  

     - Calculate the total power of each circuit's electrical appliances to ensure that the current of a single circuit does not exceed the rated load of the distribution box (e.g., C10600 is usually suitable for 10A-63A circuit breakers, which should be selected according to actual configurations) to avoid overload.  

II. Operation Specifications During Installation**  

1. **Wall Grooving and Box Fixing**  

   - **Grooving Requirements**  

     - Cut a flat groove in the wall according to the size of the distribution box (the dimensions of NEX5-C10600 are commonly about 300mm×200mm×100mm). The groove depth should ensure that the cover is flush with the wall after the box is embedded, with an error of no more than 5mm.  

   - **Fixing Method**  

     - Place the box in the groove, calibrate the verticality with a spirit level (deviation ≤2mm), and fix it with expansion screws through the reserved installation holes on the box to ensure the box is firm and free from shaking.  

2. **Wire Connection and Component Installation**  

   - **Power Off Operation**  

     - The main power supply must be disconnected before installation to avoid electric shock risks. The incoming power can be cut off through the community distribution box or outdoor meter box.  

   - **Wire Handling**  

     - When stripping the wire insulation layer, the length should be moderate (about 10-15mm) to avoid damaging the wire core. Multi-strand flexible wires need to be crimped with cold-press terminals before being connected to the terminal block.  

     - Distinguish between live wires (L, red/brown), neutral wires (N, blue), and ground wires (PE, yellow-green双色). Connect them to the corresponding terminals according to the circuit identification. The ground wire must be separately connected to the box's grounding terminal block, and mixing with the neutral wire is strictly prohibited.  

   - **Circuit Breaker Installation**  

     - Snap the suitable circuit breaker (e.g., Chint NXB series miniature circuit breakers) onto the distribution box rail to ensure a firm snap-in. When wiring, tighten the screws (torque about 2.5N·m) to avoid poor contact causing heating.  

3. **Grounding and Protection Treatment**  

   - The box must be reliably grounded by connecting the ground wire through the grounding terminal block, and the grounding resistance should be ≤4Ω, which can be detected with a grounding megger.  

   - When wires pass through the box's holes, install rubber wire protectors to prevent wire abrasion and破皮 (破皮), improving insulation safety.  

III. Post-Installation Inspection and Testing**  

1. **Line Inspection**  

   - Visually check whether all wiring terminals are loose, whether wires are tangled or squeezed, and whether circuit identifiers are clear (e.g., label "Lighting 1", "Air Conditioner", etc. with label paper).  

   - Use a multimeter's ohm gear to measure the insulation resistance between the live wire and neutral wire, and between the live wire and ground wire of each circuit. The resistance should be ≥0.5MΩ. If the resistance is too low, check for short circuits or leakage hazards.  

2. **Function Testing**  

   - After connecting the main power supply, close the circuit breakers of each circuit in sequence to test whether the corresponding electrical devices work normally (e.g., lights turn on, sockets are powered).  

   - Press the test button of the leakage circuit breaker and observe whether it trips within 0.1 seconds. If it does not trip, replace the leakage protector immediately.  

   - Simulate an overload scenario (e.g., connect high-power electrical appliances) to check whether the overload protection acts sensitively. The circuit breaker should trip within 1 hour at 1.45 times the rated current.  

IV. Safety and Specification Key Points**  

- **Professional Operation**  

  - Installation must be carried out by professional electricians with certificates. Non-professionals are strictly prohibited from operating independently to avoid accidents such as short circuits and leakage caused by incorrect wiring.  

- **Compliance with Standards**  

  - Ensure that the installation process complies with the *GB 50054-2011 Code for Design of Low-Voltage Electrical Installations* and local electrical installation standards to avoid non-compliant construction.  

- **Post-Installation Maintenance Reservation**  

  - The cover should open easily for subsequent maintenance, and the cover locks or screws must be complete to prevent children from touching internal components by mistake.  

Summary**  

The core of installing the Chint NEX5-C10600 distribution box lies in "safe planning, standardized wiring, and reliable grounding". Every step from environmental site selection to function testing must be strictly controlled. If unfamiliar with the operation, it is recommended to contact Chint's official after-sales service or professional electrical services to ensure no hidden dangers in electrical safety.
