It is a national mandatory standard to adopt protective grounding for submersible pumps. Only by adopting protective grounding can the personal safety during use be ensured. If the metal casing of the submersible pump is grounded with the grounding body conforming to the national standard, when the casing of the submersible pump leaks, the current flows through the metal casing of the submersible pump, the protective grounding wire, the grounding body, the ground, the working grounding wire of the transformer and the power supply to form a closed circuit. When the leakage current is too large, especially when the live wire touches the shell, the protection device of the submersible pump can be activated to cut off the power supply of the leakage submersible pump.

The submersible pump works in the water, and it is easy to leak electricity and cause power loss or even electric shock. If a leakage protector is installed, as long as the leakage current value of the submersible pump exceeds the operating current value of the leakage protector, the leakage protector will cut off the power supply of the submersible pump.
There are many types of submersible pumps that can produce water in both forward and reverse rotations, but the water output is small and the current is large during reverse rotation, and the motor winding will be damaged if the reverse rotation time is too long. Therefore, the submersible pump should be connected to the power supply before entering the water to check whether the rotation direction is correct.
