Someone who understands electricity comes in in terms of electrical safety .

First of all, I would like to express my great appreciation for your creativity, you are a person who loves to use your brains, and if you are young and can stick to it, you will definitely achieve something.

However, this water heater of yours is too simple, making people speechless, to be clear, this grounding has no effect.

If it is so hot that it may not leak, but the probability of leakage is greater, because it is related to human life, it can only be considered that it will definitely leak, so although the water sprinkled on the body may not necessarily cause an electric shock accident, it must be considered that there will definitely be **.

So it's best not to use this device!

But then again, if you don't allow it, this thing can also save the emergency, for example, just like the traffic rules stipulate that pedestrians are not allowed to cross the road, saying that they will be hit by cars, but they are all wearing, and there are many who are killed by the collision, and there are many more who do not die.

There are two ways that you can use this, and have a certain degree of security (complete safety is impossible), one is that you simply don't want this grounding wire, install a leakage protector in front of the hot socket to make a switch, the other is that the grounding wire is changed to a zero wire (must be a confirmed zero line, and every time you use it, you have to use a test test to test it), the advantage of the first method is to install it once, as long as the leakage will trip, the safety performance is relatively high, the disadvantage is that if you wash the fart just leakage, although you can't kill you, Hemp is going to be numb, and you may have to fall a little, so it's best to pray not to hurt the critical parts. Of course, you have to come up with ideas, it seems that you are a model of thrift, but for the sake of the highest interests ——— the right to life, the expenditure point is still necessary.

It should also be noted that do not use counterfeit and shoddy products, and it is best to ask an expert to install it.

The advantage of the second method is obviously to save rice, but the disadvantage is troublesome, one is that I don't know if you can get the zero line to clear what it is, and can you insist on measuring it every time you use it? What's more uncertain is whether your tester is good?

If you must use it, in addition to being able to meet the above description, it is also important that the fuse in your home should be very sensitive. And I guess you can't guarantee this, it seems that you don't want to pay for this electricity bill yourself?!

The conclusion is that it is better not to use it, if it must be used, of course I can't object to it, and it is also fraudulent to use it! But I'm not responsible, in fact, I can't afford to lose it, and I definitely don't want to bear it. Use the first one, right?!

LZ: Do you think the anti-theft net is the ground, if the heating pipe leaks, it will electrocute you, man.

It's dangerous, the ground wire you connect to the burglar window doesn't work at all. Don't do that.

1》Fast heating (electric heating pipe) in the resistance wire is wound into a spiral coil through asbestos powder (heat-resistant insulating powder) isolation as an insulator, once damaged (usually burned out), the heating wire is spring-like, and the probability of communication with the metal shell reaches 90% or on, leakage is difficult to avoid, electric heating pipe leakage through water conduction, the human body immersed in water can be imagined.

2》The grounding shown in the diagram is useless, if there is leakage, the probability of death is nearly 100%; The qualified special ground wire is connected to the metal shell of the electric heating pipe, and once the leakage is passed, it will pass through the ground wire circuit to form a large current to cause the circuit breaker to trip and cut off the power.

Heating fast is actually heating with heating wire, although the new insulation can be, but once burned out, it is easy and likely to break through the protective layer to cause leakage, if the leakage through the water on the human body of course will be electrocuted, the current will be smaller than the direct electric shock, but the same can cause death, the grounding method on the figure is definitely not good, first connected to the window, the resistance to the ground is too large, can not play the role of grounding, if connected to the water pipe (galvanized) can also. Secondly, the metal appearance of the bather does not work, and the leakage is in the bucket, and the metal exterior is not in direct contact with the water in the bucket. It may be better if you put it directly in the water.

But it will still have an impact on the human body, but it will reduce some current. It is better for you to add a leakage switch to heat quickly, it will be safer, the leakage switch should choose a little faster than the heat to work, the current that heats up fast = wattage 220V. The above is for your reference.

Safety first!
