How does the red light on the plug of the electric water heater flash?
High-power sockets such as electric water heaters must be equipped with leakage circuit breakers in their circuits-the leakage circuit breakers will automatically detect the leakage current in the circuits, and once people get an electric shock, they will cut off the power supply at the first time.

Grounding wire method of electric water heater
1. Observe whether the electric water heater connector has a ground wire. Generally, three wires are used, namely, live wire, zero wire and ground wire. The middle vertex angle of the fork is the ground wire.
2. The electrical wiring plug is also triangular, and the top foot is the ground wire.
The regular cable socket in the market has been connected with the ground wire. If you connect it yourself, connect a separate line at the top corner and lead it out. At the same time, the jumper must be grounded and connected to the earth.
4. Inside the electric water heater: except the live wire and the neutral wire, it is directly connected with the working pipe. The grounding wire is mainly connected to the conductor part of the outer wall of the hot water working room. If there is a leak, it will spread to the earth through this wire.
