Anonymous users2024-01-24lq9268 answered exactly right, one more point. Yellow, green and red three-color Chinese standards are A, B, C three-phase, commonly speaking, it is three live wires, the voltage between them is 380V, ABC three-phase any one to the other line voltage is 220V, usually most of the blue line as another line, kitchen appliances due to the humid environment will be due to insulation decline and leakage, to prevent electric shock household appliances shell must be grounded protection, grounding protection line used to use black wire, because the yellow, green and red three-color line is long in addition to the construction of the hand is very dirty, long time and black line should not be distinguished, Later, the standard stipulated that the grounding wire must be yellow and green two-color wire.
At present, the electricity consumption of ordinary families is small, and they are all single-phase households, and now most villas are three-phase households, which need to be paid attention to.
In addition, it should be pointed out that this standard is suitable for China, for example, in the United States, the green line indicates the grounding wire, not in China, and the phase wire must not be mistaken.

Anonymous users2024-01-23According to the color: yellow, green, red for the phase line (usually said live wire L), blue for the zero line (N), yellow and green two-color line for the ground wire (the specification stipulates that the yellow and green line shall not be used as other lines under any circumstances), and there is a black line, which used to be used as a ground wire, and now it is also used as a zero line, so the blue wire is connected to the zero line (N), and the yellow and green line (hehe, correct it is not yellow) grounding wire.

Anonymous users2024-01-22In general, the red wire is connected to L (live wire), the blue wire is connected to N (neutral wire), the yellow wire (yellow and green strip wire) and the yellow wire is connected to the ground wire T (middle).

Anonymous users2024-01-21Under normal circumstances, the red line is connected to L, N is connected to the blue wire, and the remaining yellow line is connected to the middle ground wire.
According to the current standard in China, from the line color, it should generally be red in the live line, green or yellow in the zero line (some are black), and the ground wire is yellow and green. >>>More
The ground wire of the three-pin socket in the kitchen has weak electricity, and the reason for it is that the ground wire of your entrance wire is not connected or loose. You will induce the voltage of the live wire to the ground wire, so if the electricity leaks, it will definitely be unsafe, and it may cause electric shock, so it doesn't matter if you connect the ground wire, it will return to normal.
The regular plug-in board is marked with load, as Gao is an amp, can only plug in a dry watt power of electrical appliances, two, plug in two large electrical appliances caused by tripping is to protect the plug-in board from being short-circuited and burned, three, high-power plug-in board and fuse matching, if the insurance load is greater than the total load of the plug-in board, it is dangerous
From what you said, this cable is a lighting tap line, not a power supply. It cannot be used as a power supply. (Socket). >>>More
Is there electricity when plugged into the BC group with the shell? If there is, there is leakage of electricity in the internal circuit of the refrigerator to the ground (case), for many reasons, such as insulation damage, moisture, etc., because the case is grounded, this electric connection with 109V to the ground of the power supply system will of course jump switch.
