Standard for Wiring Connections of Lighting Electrical Ready Boards
The standard for wire connections in lighting Electrical Ready Boards is an important part of ensuring the safe and reliable operation of electrical systems. The following are some key standard requirements:
1、 Wire selection and cross-section
Wire material: Copper core wires that meet national standards and have good conductivity and mechanical strength should be selected.
Wire cross-section: It should be selected based on factors such as load current, line length, and allowable voltage drop to ensure that the wire cross-section can carry normal operating current and leave a certain margin.
2、 Connection method and requirements
Connection method: The wires should be connected by bolts, plugs, welding, or crimping to ensure a firm and reliable connection.
Connection requirements: The wire connection should be tight, not damage the wire core, and continuous. The cross-sectional area of the wire pressed on both sides of the screw under the washer should be the same. The number of wire connections on the same electrical device terminal should not exceed 2 to prevent loosening and overheating.
3、 Wiring and Identification
Wiring requirements: The wiring inside the box should be neat, without twisting, with complete circuit numbers and correct labeling. The wires should be tied into bundles with appropriate allowance.
Identification management: Wires should be labeled with insulation sleeves of different colors to distinguish between different circuits and voltage levels. At the same time, the name, number, and purpose of each circuit should be indicated on the door of the Electrical Ready Board.
4、 Grounding and Protection
Grounding requirements: The lighting Electrical Ready Board should be equipped with a dedicated grounding terminal, and the cross-section of the grounding wire should meet the requirements and be effectively connected to the main grounding terminal of the equipment.
Protective measures: Overcurrent protection devices and residual current action protection devices should be installed inside the Electrical Ready Board to ensure personal and equipment safety.
In summary, the standards for wire connections in lighting Electrical Ready Boards cover multiple aspects such as wire selection and cross-section, connection methods and requirements, wiring and labeling, as well as grounding and protection.
