Wiring for the activation of leakage protection

The specific wiring methods may vary slightly depending on the type of leakage protector and the application scenario. The following takes the common household single - phase leakage protector and three - phase four - wire leakage protector as examples to introduce their basic wiring methods:

#### Wiring of household single - phase leakage protector
- **Power inlet connection**: Generally, a leakage protector has two inlet terminals, marked as L (live wire) and N (neutral wire). Connect the live wire from the distribution box to the L terminal and the neutral wire to the N terminal. When wiring, make sure the stripped length of the wire is appropriate. After inserting the wire into the wiring hole, tighten the screw to ensure good contact and prevent loosening and overheating.
- **Load outlet connection**: The leakage protector also has two outlet terminals, which are respectively connected to the live wire and neutral wire of the load. They are usually marked as L1 and N1. Connect the live wire of the load (such as electrical equipment) to the L1 terminal and the neutral wire to the N1 terminal.
- **Grounding connection**: To ensure safety, the leakage protector usually has a grounding terminal marked as PE. It needs to be connected to a reliable grounding body, such as the grounding grid of a building or a special grounding electrode. The grounding resistance should meet the requirements of relevant standards, generally not exceeding 4Ω.

#### Wiring of three - phase four - wire leakage protector
- **Power inlet connection**: A three - phase four - wire leakage protector has four inlet terminals, marked as L1, L2, L3 and N respectively. Connect the three live wires of the three - phase power supply to the L1, L2 and L3 terminals respectively, and connect the neutral wire to the N terminal. When wiring, connect them correctly according to the phase sequence to avoid reverse connection.
- **Load outlet connection**: There are correspondingly four outlet terminals, marked as L11, L21, L31 and N1. Connect the three live wires of the three - phase load to the L11, L21 and L31 terminals respectively, and connect the neutral wire of the load to the N1 terminal. For some unbalanced three - phase loads or mixed loads containing single - phase equipment, the connection of the neutral wire is crucial and must be ensured to be correct and reliable.
- **Grounding connection**: Similar to the single - phase leakage protector, the three - phase four - wire leakage protector also has a grounding terminal PE, which needs to be connected to a good grounding device.

When wiring, strictly follow the instructions of the leakage protector to ensure correct wiring. Before wiring, be sure to cut off the power supply to ensure operational safety. After wiring, a leakage test can be carried out to verify whether the leakage protector is working properly.#tiktokrefugee#cat#tiktokban#china#抖音难民#transformers #transformer #electrical #technology #factory #foryou #viral #shortvideo #manufacture #machine #power #shorts #trending #wiring #factorywork #electricalengineering #powertransformer #electriacaltransformer #manufacturing #process #manufacturer #manufacturingprocess #HighVoltageWinding #usa #canada #australia #uk#dailyvlog #daily #bluecollar #Tesla#WorkshopDaily #electricwire #powerengineering #transformer #foilwinding #lowvoltagenation #electricalengineering #LowVoltageFoilWinding #FoilWinding #ElectricalEngineering #TransformerDesign #InductorDesign#TransformerTechnology #ElectricalEngineering #FoilWinding #TransformerManufacturing #EnergyEfficiency #ElectricalDesign #TransformerWinding #EngineeringInnovation #TransformerTechnology #CopperFoilWinding #PowerTransformers #EngineeringTechniques #ElectricalComponents
