Home assembly electric box features and precautions

Distribution boxes play a crucial role in modern households, making it essential to maintain and clean them properly. Everyone should be mindful of these systems when performing cleaning or maintenance tasks. Ensuring the integrity of the box not only prolongs its lifespan but also enhances electrical safety for everyone in the home. Below are some key characteristics and important precautions to consider when handling assembled electrical distribution boxes.

1. The wiring inside the distribution box should be neatly arranged without any splices. All wires must be securely connected, ensuring that the core is not damaged. The cross-sectional area of the wires on both sides of the screw under the washer should match, and no more than two wires should be connected to the same terminal. All components, such as anti-loose washers, should be complete, and the wire connections must be tight and secure.

2. The vertical alignment of the distribution box is an important factor. If the box height is less than 50cm, the allowable deviation is 1.5mm. For boxes taller than 50cm, the allowable deviation increases to 3mm. Lighting boxes should be embedded and installed firmly, with the bottom edge positioned approximately 1.8 meters above the ground level.

3. The switches within the distribution box should operate smoothly and reliably. It is important to have a leakage protection circuit in place, with the leakage current protection device having a rated operating current of no more than 30mA and an action time of less than 0.1 seconds.

4. In the lighting box, separate bus bars should be used for the neutral line (N) and the protective earth line (PE). These lines should be properly distributed through their respective bus bars to ensure correct and safe electrical connections.

5. The metal frame of the distribution box must be reliably grounded (PE) or connected to zero (PEN). The door of the box should open freely, and if there are electrical components inside, the connection between the door and the grounding terminal of the frame should use a bare copper wire and be clearly marked.
