Grounding issue
Thread Content
In SH-T3081, there is a question: How is it achieved that both ends are connected to the ground?
The connection of both ends to the protective ground mentioned in SH-T3081 generally refers to the simultaneous connection of both ends of the device or circuit to the protective grounding system. The purpose of doing this is to ensure that fault current can be effectively discharged in the event of a failure in electrical equipment, thereby protecting human safety and ensuring the safe operation of the equipment. In practice, it is necessary to connect the device’s grounding terminal or grounding point to the grounding electrode or grounding grid through a grounding wire, in order to ensure a low grounding resistance and reliable grounding performance. Relevant **standards and industry norms** should be followed during construction. .
Do the two ends refer to the instrument panel on the site side and the cabinet room? Should the grounding be at the Golan location on-site, or should the armored layer be led to the on-site junction box before connecting to the protective ground? Is the cabinet room used to connect the armored layer separately to the protective ground?
Generally, armored cables have a shielding layer; the outer shielding is grounded at both ends, while the inner shielding is grounded at one end. There may be an intermediate junction box for connection, or in its absence, the connections are made from the gland
