The power strip has no ground wire, how should it prevent leakage?

When the household electrical equipment does not use the leakage circuit breaker, the power strip must be correctly grounded. In recent years, the household electrical system has a leakage circuit breaker. The correct configuration is to install a two-pole total circuit breaker in the household line. The total circuit breaker is two branches. All the way is for lighting.

The other way is for the socket, the lighting does not need to install the leakage circuit breaker, the power strip should be properly configured with the leakage circuit breaker. If the leakage circuit breaker is installed and the ground wire is connected, it is good in terms of personal safety, but may increase the action of the circuit breaker. The probability that this leakage current is not due to the flow of the human body.

If there is land soil outside your house, use four 0.8-meter angle steel or flat steel to weld into a “王” shape, as a grounding body, buried below 0.7 meters underground, welding a steel bar from the grounding body to the ground, and then using a The 4mm2 copper wire is firmly soldered to the steel bar by soldering and introduced into the house as a grounding wire. The protective ground wire of all appliances can be accessed from here. If you are only the computer protection grounding, you can put this ground wire into the computer power strip and crimp it to the ground terminal. This method is safe and reliable and works well.
