Specification For Grounding And Protection Measures Of Lighting Electrical Ready Board

The grounding and protection measures specifications for lighting Electrical Ready Boards are key factors in ensuring circuit safety and stability. The following is an overview of their relevant specifications:

1、 Grounding specifications

Grounding wire material: The grounding wire should be made of high-quality copper wire with good conductivity and corrosion resistance, ensuring that the grounding resistance is as small as possible and the grounding is reliable.

Grounding depth: The grounding wire should be directly buried underground, with a depth not less than the specified value, usually not less than 0.8 meters, and should maintain a necessary distance from pedestrian areas to avoid damage.

Grounding resistance: Grounding resistance is an important indicator for measuring the quality of grounding, which should comply with national standards and generally not exceed 4 ohms. After the grounding is completed, a grounding resistance test should be conducted and the test results should be recorded.

Regular inspection: Due to the constantly changing outdoor environment, it is necessary to regularly check the grounding quality and promptly identify and address any issues.

2、 Standardization of protective measures

Leakage protection: Leakage protectors should be installed in the Electrical Ready Board. When leakage occurs, the leakage protector can quickly cut off the power supply to prevent electric shock accidents.

Short circuit protection: Install a short circuit protection device that can quickly cut off the faulty circuit when a short circuit occurs, preventing safety accidents such as fires.

Overload protection: The Electrical Ready Board should have overload protection function, which can automatically cut off the power supply when the current in the circuit exceeds the rated value, protecting the safety of the circuit and equipment.

Lightning protection measures: For outdoor lighting Electrical Ready Boards, lightning protection measures should be considered by installing lightning arresters and other lightning protection equipment to avoid electrical faults or equipment damage caused by lightning strikes.

In summary, the specification of grounding and protection measures for lighting Electrical Ready Boards is an important guarantee for ensuring circuit safety and stability. During the design and installation process, relevant standards and specifications should be strictly followed to ensure that all measures are effectively implemented.
