Power distribution cabinet is an important component in building electrical installation. It is directly related to the functions of power distribution, electrical control and power supply, and is closely related to the overall safety of the building. However, in the construction of high voltage distribution box of building electrical installation, it is easy to appear quality common problems, which affect the quality of building electrical installation. Judging whether it is line leakage or electrical leakage is the first and simplest step to find out the location of the leakage point. We will talk about it in detail below.

Power distribution cabinet is an important component in building electrical installation. It is directly related to the functions of power distribution, electrical control and power supply, and is closely related to the overall safety of the building. However, in the construction of high voltage distribution box of building electrical installation, it is easy to appear quality common problems, which affect the quality of building electrical installation. Judging whether it is line leakage or electrical leakage is the first step to find out the location of the leakage point, and it is also a simple step. We will talk about it in detail below.
distribution cabinet manufacturers: distribution cabinet circuit leakage or leakage?
This one is very simple. It does not require any tools or expertise. Any adult can do it.
The method is to unplug all electrical appliances, turn on the power, insert a confirmed electrical appliance in all sockets, and test one by one. If the line continues to trip after closing, it is proved that the line is leaking. If there is no trip after closing, it is proved to be leakage.
Distribution cabinet manufacturers: determine which electrical leakage
If it is determined that the electrical leakage is caused by an electrical appliance and there are multiple electrical appliances in the loop, it is necessary to determine which electrical appliance is leaking at this time.
The method is also simple, that is, after closing, plug in the electrical appliances one by one in the circuit, and the plugged electrical appliances trip, that is, the electrical appliances that leak electricity. Remember this electrical appliance, turn on the machine and continue to plug in other electrical appliances to check whether other electrical appliances also have leakage. Find out which electrical appliance is leaking, replace or repair the appliance.
Distribution cabinet manufacturers: determine which line leakage
If it is determined that the line is leaking, we need to replace the leaking line. Of course, before that, we need to know which line is missing.
If there is an electric meter, of course, you can use the shaking meter to test all the circuits in the loop in turn.
If we don't have the tools at hand, we can still test it by observing the itinerary.
The test method is to remove all switches, sockets and cover plates in the circuit, and disassemble the wiring head in turn from far to near (distance from the distribution box). Turn on one switch at a time (the removed connector should be wrapped with insulating tape. If it is too troublesome, it can be pulled outside and must not touch anything). If the circuit breaker stops tripping when one of the conductors is removed, a section of the conductor from the connector to the last removed connector is proved to have leakage.
Power distribution cabinet manufacturer: judge zero line or fire line leakage
How to judge the zero line or the fire line leakage? The fire line will not leak, or even if the leakage will not trip.
As we said above, after unplugging all electrical appliances, turn on the power and plug an electrical appliance into each socket for testing. If the trip is only after the electrical appliance is plugged in, it is proved that the neutral line is leaking; if the trip occurs before the electrical appliance is plugged in, it is proved that the fire line is leaking.
At this time, the location and line properties of the leakage line are clear, and we can replace the leakage line.
