Ask an experienced electrician for some advice, and an experienced electrician can help me

Dizzy, the flickering people of the property, they don't understand. The current to which the wire is subjected and the cross-section of the wire (squared, 4 squares...) The volume is related, and the laying method (buried, surface-mounted, pipe-wearing...)

The relationship is not too big, the air conditioning line should be one-to-one (16A air opening directly to the air conditioning socket, this line is dedicated, it is forbidden to connect other sockets in parallel). There is no problem with the wires here with the national standard squared, and it doesn't matter how they are laid.

Materials you'll need: 3 for 2p 16a open space, 3 for 16a sockets, 3 sets of square wires (live wire: red; Zero line:

Blue; Grounding wire: two-color wire. ), 3 bottom boxes (open boxes or cassettes, as needed), 20pvc line pipe (3cm trunking) length as needed; Auxiliary materials (direct, glue, expansion tube...)

Hello, there is no end to learning about the industry related to electricity. You can't just think about which certificates you want to take, of course the certificates are to be taken, they are your entry threshold. I think that in the examination, you can have an electrician Internet certificate and an electrician maintenance certificate, and the examination grade certificate is a matter of the future, and it is something that you will consider after engaging in this industry.

Now the key is how good your skills are, whether you can use what you have learned after taking up the job, and whether you can deal with practical problems is the key.

It depends on the wire diameter of your socket, how big it is, you catch the old house, the oldest house, the wire is aluminum wire, if the aluminum wire needs 4 square meters,,, if it is copper wire square.

It also depends on your entry line.,The current entrance lines are 10 square meters.。。 You don't need to.,You can wire it directly indoors.。。

If not, it will be wired directly at the end of the meter,,, and it will be seen how big the wire diameter in front of the meter is. It does not need to be replaced.

My view is that you should, re-wire after the table.

I feel that the situation described is like a fan burned, and some fans are too seriously aged. If you smell it, if you burn it, it is generally the weakest place, not necessarily the air switch is weak.

Are there any other openings or fuses before and after this opening?

If it is indeed not, it means that the joint of the wire is not firmly connected and the circuit is broken, and it is very difficult to check if it is a dark wire.

Well, in fact, after reading the first half, you can already judge that the wire is connected wrong, this problem is best to have **, and to use a test pen to measure which is the live wire, you must also find out which is the zero line, which is the ground wire. These 3 wires find the type of switch (circuit breaker, air circuit breaker) at the root and connect it to the corresponding wiring. The main incoming line should be right, and the outgoing line to each electrical appliance should be right, and it will also be very dangerous.

If you really can't find a property, if you don't have a property to find an electrician, don't think it's simple to take it as you wish. Because your ground wire is wrong, the zero line is wrong, and the equipment with three-phase joints is easy to leak, and the consequences are unimaginable, such as water heaters.

Your total opening is reversed zero-sum! This must be handled by an electrician!

You have to take an operation certificate to do electricity, and if you want to have a high salary, you can take a grade certificate, including junior, intermediate, high, technician, and senior technician. That's up to you, good luck.

In Shenzhen, the operation certificate (work certificate), together with the training fee of the junior electrician certificate, the teaching material fee is more than 800, if there is a grade certificate, only the operation certificate can be examined. I have taken the test, in Futian District, Shangmeilin Yuehua Road, Shenzhen Technical School, the former City Skills Training Center.

Your current certificate only shows that you know a little electricity, but to be an electrician, you have to take a certificate issued by the Safety Supervision Bureau, you can go to the labor market to take the test, the tuition fee is more than 200, and you can study for a few days.

The level of salary is not what level you can take to get a certificate, the job of an electrician requires skills and experience, and after a long time, there is hope for wages. . .

The three certificates of being an electrician are indispensable, and it is very troublesome to have problems without that.

If you go to the society to take the electrician certificate, ** it is different from place to place, and it will cost 400-600 yuan; It is to register for the assessment at the work safety supervision and administration bureau where your unit is located, and you must have a certificate from the unit before you can register for the test at the work safety supervision bureau. When the two certificates recognized by the electrician society are:1.

Electrician induction certificate of the Work Safety Supervision Bureau; 2。Personnel Labor Electricity Salary Certificate (Primary. Intermediate.

Advanced three) electrical salary certificate, also called electrician grade certificate, can also be tested in the school, the higher level is better!

Such a big thing is only given 5 points!

Electricians also look at what unit, monopoly power grid enterprises are good, and electricians in general factories are not very good. That industry is inseparable from electricity, it is easy to find a job as an electrician, and it is easy to deal with any problems with the circuit at home if you understand some electrician technology.

The Electricity Bureau is a monopoly industry, of course.

When I was studying, the books I studied were: "Electrical Engineering" compiled by the Department of Electrical Engineering of Zhejiang University, the first volume is the basis of circuits, the middle volume is electronic technology, and the second volume is the contact control of motors and relays. Recommend this book to you. Published by the People's Education Publishing House.

I've been in the line of the resistance furnace haha,Buy this called Practical Circuit 300 Q. Find some more books to read. Secondary school textbooks are practical and comprehensive things, I think you mainly start with electrical control. It's a little more fun that way.

The training school is only organized to cope with the exam, and in order to obtain the certificate, it is not easy for you to learn things, and the things you learn during the training are all theories, and there is no use in practice.

If you finish studying, you should still look for a job as an internship, do more hands-on operations, and find an older electrician master to take it, and it will be almost the same in one or two years.

If you have the conditions, you will learn, some companies require you to have a special operation certificate (work certificate) and professional qualification certificate (grade certificate), high-voltage certificate, the more you learn, the easier it is to find a job.

There are two main types of certificates for electricians and welders, "Special Operation Certificate" (employment certificate) and "Vocational Qualification Certificate" (grade certificate), which are issued by the safety production supervision and management department and the labor and social security department respectively.

The grade certificate and the work permit are issued by the two departments, and they must be held in accordance with the regulations.

Go to the Labor Bureau and the Work Safety Supervision Bureau to ask. Many schools, or you go to the local information port to search.

I don't even have a junior high school education, and I've been working for 7-8 years. Nowadays, training and learning are only for exams. When you are looking for a job, you first find a factory, and the master will take you for a few months. Learn more and watch more, don't be afraid of getting dirty and tired.

You can learn things without going to class, and you may not be able to learn things in class, it depends on whether you recognize learning or not.

If you have a certificate, you can find a job. I think it's better to repair electricians. Because electricity is needed everywhere.

Based on years of experience with apprentices, there are some ideas that I would like to share with you now.

1. Be familiar with the structural principle and control principle of each electrical component (including the normally open and normally closed buttons).

2. Familiar with the working principle and electrical action principle of the equipment.

3. Familiar with the use specifications and related safety regulations of low-voltage electrical equipment.

4. Draw the control loop of each cabinet by yourself, this is a bit difficult, you can draw the simple one first, and then gradually draw the complex one.

In this way, you can get twice the result with half the effort.

No electrician can see through a complex distribution cabinet at once, unless he designs it himself. You can find a drawing, you will quickly understand it when you compare the real thing, and if you don't have a drawing, you can also draw it yourself according to practice, so that you can understand it more thoroughly.

Generally, there are two kinds of circuit walking patterns of distribution boxes and distribution cabinets.

First, the left power supply, the right load.

2. Power up, load down.

What AC contactors, relays, are counted as the load part, the principle of electrical equipment can be, check the electrical equipment manual of your unit, the unit will archive each electrical equipment, our unit is like this, you can find the number
