Electrical distribution box zero line and ground line can be shared?

Do you want to know electrical distribution box zero line and ground line can be shared?

1, in accordance with the electrical installation specifications, the zero and ground lines in the power distribution box should never be connected together zero and ground.

2, if the zero line and ground are connected together, the leakage cannot be detected, there is a safety hazard to, will also lead to the circuit breaker can not send power. When the external zero line due to a break in the ground will be charged, the ground line is bad when the household appliances shell will be charged, which is very dangerous.

3, although the zero line is also grounded, but with electronic equipment and three plugs and sockets on the grounding foot position has the essence of the difference. Zero line grounding is a circuit of the power supply line, that is, called the power supply ground. While electronic equipment and three plugs and sockets on the grounding feet but belong to the protection of the ground. They are different is that when the end of the zero line break or poor contact, the zero line will become the fire line, with electricity, if you connect the zero line with the ground, the zero line will be transformed into the fire line through the ground line connected to the electricity to the equipment shell, so that the electronic equipment as a whole with electricity, easy to cause electric shock accidents.

4, the ground is only connected to the shell of household appliances, and then connected to the ground, when the leakage of electrical appliances, such as the power line core and electronic equipment shell contact, will make the shell charged, if there is no or no ground wire, the person in touch with these household appliances will have electricity through the human body and electrocution accidents, and connected to the ground, the leakage of electricity to the chassis will be transmitted from the ground to the ground, when the person touches the appliance will Will not have electricity to the body, will not cause electric shock accidents.

Therefore, the ground is a protective ground, different from the zero line, the two can not be connected together.
