Description

The working grounding wire is a safety tool that short-circuits the grounded device. It connects the electrical equipment to the ground, making the device at zero potential.

[0036] When the device is in use, the whole device is leveled on the ground, and the device is hung through the hanging seat 13. Whether the level 12 is in a horizontal state is observed, and the balance device 14 of the four corners is adjusted correspondingly, so that the whole device is in a horizontal state.
