There is no danger, because the energy meter is in series ** road, the purpose is to measure the amount of electricity. If your energy meter only has two binding posts, then either on the live wire or on the neutral line, you just make the meter not work, loop you.
-
The access control lock is indeed the kind of fire line that bumped together, and the other end is whether the four-door controller has no effect, indicating that there is indeed a certain kind of uh implication between them, so you have to rest.
-
The current access control lock, his rocket, and its zero line have collided together, and his other four controllers are still influential, so we should all better control it during the security period.
-
Hello, this one doesn't have much of an impact. Be sure to pay attention to the safety of electricity, otherwise it will be too dangerous.
-
It may be that the wiring on these two sides is different, so this will happen.
-
Look at what a lock is, how many A power supplies are used, the general power supply problem will be greater. We've had this issue before, or the controller is broken,
-
I'm now with the bump and then the other end is able to control the automatic gas will not affect you in the photo will not cause an effect okay?
-
Together, does it affect this? If they are touched together or are inseparable.
-
Maybe he's going to have a heart, that's why his doorbell is like this, and it's different.
-
Control, guidance as this certificate in order to do a good job of economic control, as the United States also divided into classes.
-
The zero line of the access control lock is touched together, and the four-door controller at the other end will still have a certain impact, which may affect the normal start and operation of the four-door controller.
-
If the zero line touches together, does the door wire at the other end have any effect? It should have an impact.
-
The door lock is touched by the zero line of the live wire, and the other end of the four-door controller has no effect, and they are not affected under normal circumstances.
-
Activate the lock, the zero line touches together, and the other end of the four controls those have no effect, I thought these two were not affected.
-
If the access control lock is in the live line, if the zero line touches together, the words of the four-door controller at the other end are affected, and he may burn out.
-
The zero line of the access control fire saving line touched together, and the 4-door controller at the other end had a certain impact.
The correct connection between the live wire and the neutral wire is shown in the following figure: How to connect the live wire and the neutral wire? Wiring is an important job in home renovation. >>>More
Firewire wire colors are usually red, green, and yellow; The color of the neutral wire is mostly black and blue; The ground wire is generally a yellow and green wire. Some electricians do not follow the standard wiring when wiring, and you can also distinguish between the live wire and the neutral wire through tools such as electric pens and universal meters. >>>More
Measure with an electric pen the reason why both the live and neutral wires are bright: >>>More
When energized and measured with an electric pen, all the bright ones are the live wires, and the dark ones are the zero wires >>>More
The blue line is the zero line, and generally speaking, the fire line is represented by red, while the zero line is blue, which is a cool color and relatively not particularly dangerous. In addition to this, we can also use the electric pen andMultimeterto distinguish between the live line and the neutral line. >>>More
