Can the terminal block in the lab be grounded
Electrical laboratory grounding requirements are relatively strict. Can be buried in the ground surface hanging tin copper plate grounding body, the area should be large enough, generally double-sided area should be greater than 2 square meters. Buried to be deep enough, generally about 2 meters. Lead wire with a cross-sectional area of more than 35 square millimeters of yellow and green grounding wire, in the center of the grounding body with tin solder firmly after the lead. After the above strict production, lead to the laboratory when the grounding resistance will meet the requirements of less than 2 ohms p>
