The problem of distribution box installation, how to prepare the distribution box? What should we pa

I don't know why you want to change the distribution box, because you don't trust the developer, or if you think there is a security issue. If it's the latter, you can find a friend who understands electricity to check it. It is enough to eliminate the existing problems. If it is the former, you can find someone or the relevant electrical department to verify it.

I guess it will help you.

This kind of small distribution box manufacturer is not responsible for installation. If you want to change it, you can find someone from a home improvement company to replace it for you, and they will design the size of the distribution box and the internal switch configuration according to your requirements.

The distribution box generally does not need to be replaced, at most, it is to change the cover plate, that is, to change the decorative baffle on the surface, measure the distance between the screw eyes on both sides of the distribution box, buy it according to the distance, but it is possible to sell it is a set Buy it back The box does not need to be installed by others It is to remove the two screws on both sides and then install the new one It is very simple Which manufacturer will not care if you really want to find an electrician.

It should be installed in a dry and ventilated area, and there should be no obstructions, so that it is easy to use. The distribution box should never be installed in the box to prevent fire.

The distribution box should not be installed too high, and the general installation elevation is meters for easy operation.

The electrical pipe into the distribution box must be fixed with a lock nut.

If the distribution box needs to be opened, the edge of the hole must be smooth and smooth.

The distribution box should be embedded in the wall vertically and horizontally, leaving a gap of 5 6 mm at the edge.

The wiring in the distribution box should be regular and neat, and the terminal screws must be tightened.

The incoming line of each circuit must be of sufficient length and must not have joints.

After installation, the name of each circuit should be indicated.

After installation, the residue in the distribution box must be cleaned up.

The manufacturer is responsible for the installation, which is generally not cheap. If you don't have to change it, you have to put it forward to the property, if you take the liberty to increase the load or switch, resulting in an electrical accident, the responsibility is not small, and it is not good to enter the bureau (this accident does not only refer to your own home, because you have changed the load capacity without permission, and you have to pay for the related accidents).

The problems that need to be paid attention to in the installation of distribution box are as follows:

1.The distribution box and switch box should have the name, purpose, branch mark and system wiring diagram. 2.

The doors of the distribution box and switch box should be locked, and a special person should be responsible for it. 3.Distribution boxes and switch boxes should be regularly inspected and maintained.

Inspection and maintenance personnel must be professional electricians. During inspection and maintenance, insulated shoes and gloves must be worn and worn according to regulations, electrician insulating tools must be used, and inspection and maintenance work records should be made.

4.When the distribution box and switch box are regularly maintained and inspected, the corresponding electric Tan isolation switch of the previous level must be opened and de-energized, and the power outage sign of "no closing, someone working" must be hung, and live operation is strictly prohibited. 5.

The distribution box and switch box must be operated in the following order:

1) The operation sequence of power transmission is: the main distribution box, the distribution box, the switch box;

2) The sequence of power failure operation is: switch box, distribution box, and general distribution box. However, this is not the case in the event of an emergency in the event of an electrical failure.

6 .When the construction site stops working for more than 1 hour, the power switch box should be powered off and locked. 7 .

The operator of the switch box must comply with the provisions of the specification. 8 .No sundries shall be placed in the distribution box and switch box, and shall be kept clean and tidy.

9 .Other electrical equipment shall not be connected to the distribution box and switch box at will.

10.It is strictly forbidden to change the electrical configuration and wiring in the distribution box and switch box at will. When replacing the melt of the fuse, it is strictly forbidden to replace it with a melt that does not meet the original specifications.

The leakage protector should be started before using it every day, and it is strictly forbidden to continue to use it when the test jump is abnormal. 11.The incoming and outgoing lines of the distribution box and switch box are strictly forbidden to bear external force, and it is strictly forbidden to contact with sharp metal fractures, strong corrosive media and flammable and explosive materials.

The selection of distribution boxes should be considered from the following aspects: according to the nature of the load and the purpose. Determine whether it is a lighting distribution box or an internal power distribution box or a capacity metering box, etc.

According to the magnitude of the load current of the control object, the voltage level and the protection requirements, determine the capacity and voltage level of the switching appliances and protection appliances in the circuit in the distribution box and each branch. The structural form of the distribution box should be selected from the requirements of the use environment and use occasions. For example, determine whether to choose surface-mounted or concealed-mounted type, as well as appearance color, anti-masonry, fire prevention and other requirements.

When selecting various distribution boxes, we should generally try to pay attention to the selection of general standard distribution boxes, so as to facilitate design and construction. However, when the architectural design requires, it can also be ordered to the relevant production plant according to the design requirements for processing non-standard difficult distribution boxes.

How to prepare:1The type is determined according to the nature of the load and the purpose.

2.The level of the distribution box is determined according to the size of the load current of the control object, the voltage level and the protection requirements. 3.

According to the requirements of the use environment and occasion, the structural form is selected. 4.Try to use a common standard distribution box.

Attention Questions:1The distribution box should have a name, purpose, branch markings and system wiring diagram.

2.Someone is in charge. 3.

Regular inspection and maintenance. And make inspection and maintenance work records. 4.

The operations related to the distribution box are in a certain order. 5.Do not leave any clutter and keep it tidy.

6.It is not allowed to connect other electrical equipment at will. 7.

It is strictly forbidden to change it at will. 8..It is strictly forbidden to come into contact with sharp metal fractures, strong corrosive media and flammable and explosive materials.

(1) The distribution box should be installed in a dry and ventilated part, and there should be no obstructions, which is convenient to use.

2) The distribution box should not be installed too high, and the general installation elevation is for easy operation.

7) There can be no pressing skin, exposed copper and other phenomena during wiring; The end of the line should be avoided as much as possible, and when it must be crossed, it should be crossed overhead at the intersection point, and the distance between the two lines should not be less than 2mm.

8) After installation, the name of each circuit should be indicated.

9) After the installation is completed, the residue in the distribution box must be cleaned up.

10) Use different colors for the wires.

1) The elevation or verticality of the distribution box (panel) exceeds the allowable deviation: it is caused by the inaccurate measurement and positioning, the blind stool or the uneven ground, which should be corrected in time.

2) The iron frame is not square: if the iron frame is not straightened and aligned before installation, or the position of the fixed point is offset during installation, it should be fixed after the hanging wire is re-aligned.

3) The electrical appliances and instruments on the disk surface are not firm, flat or unevenly spaced, the indenter is not firm, the indenter hurts the wire core, and the multi-strand wire indenter is not equipped with a crimping wire terminal. The card frame is not installed under the gate, the screws should be tightened if they are not tight, and the spacing should be adjusted evenly and leveled according to the requirements. The part of the injured wire core should be cut off and reconnected, the multi-strand wire should be equipped with crimping terminals, and the card frame should be reinstalled.

4) The grounding wire cross-section is not enough or the protective ground wire cross-section is not enough, and the protective ground wire is connected in series, and these do not meet the requirements should be corrected in accordance with the relevant regulations. The PE wire terminals in the distribution box and panel are suitable for general public construction projects, and are not suitable for civil residential projects.

5) The wiring arrangement behind the tray is not neat: it should be tied into bundles according to the branch and fixed in the panel.

6) Missing parts of the distribution box (panel), such as hinges, locks, screws, etc.: all kinds of parts required for installation should be complete.

7) Iron box electric and gas welding long holes: one pipe should be one hole, should not be electric and gas welding holes, the pipe box should be flush.

9) There is no anti-corrosion on the outside of the Jianxun wooden box, and the inner wall is rough: it should be treated according to the regulations.

10) Rust of the inner wall of the iron box: anti-rust paint should be repaired.

1. Whether it is surface-mounted or concealed, it must be ensured that the box is complete and there can be no missing part. In order to make the distribution box insulated, the phase wire, ground wire and neutral wire can be installed in the power box to increase the safety of electricity use.

2. Install the distribution box in a well-ventilated, dry and easy-to-use place, and do not install the distribution box in a too high position, otherwise it will be very inconvenient in the process of daily use. In general, the height of the distribution box installation position should be less than meters, and the electrical pipe should be fixed with a lock nut.

3. When installing the distribution box, if you want to open the hole, you must ensure that the edge of the hole is smooth and flat. In order to make the home environment look more beautiful, the distribution box should be installed horizontally and vertically in the wall Changna, and the edge should flow out of the distance of five to six millimeters. The wiring of the distribution box must be kept neat, and the terminals must be fixed with screws.
