When decorating circuits, you must have heard this sentence: Many people think it's good to keep wires neat, so they just let decorator do it as neatly as possible with absolutely no regard for practicality.
Actually, neatness isn't necessarily a good thing, and it certainly isn't about making everyone run wires crookedly, there are actually "procedures" for wiring. Don't give money or they'll cheat you. terrible!
Give us a picture first, many famous decorating companies like to do this, it just looks good. For example, wiring in figure below is designed to go from point A to point B. Obviously, this can be done in a straight line, but it only takes 5 turns to turn. What does it mean? There are too many wires, and such turns at right angles are all dead ends. When something is wrong, you can’t even pump it. Who doesn’t cheat?
Some electricians do opposite, make a curved fabric. Out of curiosity, I asked decorator, who told me that this was a professional way to distribute water and electricity. The so-called "horizontal, flat, and vertical" in traditional wiring is only for aesthetics, but is completely impractical. This is a waste of materials and time. This can only be done by inexperienced or irresponsible master decorators.
The "horizontal, flat, and vertical" method has a large budget, so when laying wires, you need to look beyond appearance. you can't see anything. Be practical anyway.
The longer wire is drawn, higher labor, so many pay attention to "shortest distance between two points and one line" in mathematics when installing wires, so that wiring is neat and beautiful, which saves money.
We talked about ground wiring above, now let's talk about wall wiring, here are two places to pay attention to:
Bearing walls. For load-bearing walls, slots and wiring in wall must run vertically, and horizontal slots cannot be opened. You should be aware that horizontal slots will affect load. load-bearing capacity of a load-bearing wall.
But if you do that, you can't bury cassette, but little worker said that there is a solution. All you need to do is put a template on cassette, and then a foam panel on it. Don't expect this to be possible. If your family is also facing this situation, you should ask handyman to do it, otherwise building will be destroyed in minutes.
Meeting a good plumber is biggest success in decorating. My house is really well established. The workers seem to be very experienced.
Light wall: For light walls, horizontal grooves can be opened, but they must not exceed 50 cm, and length of inner insulating wall must not exceed 100 cm.
PVC pipe threading
The last simple point that is easy to fool is most common in finishing, that is: a PVC pipe with only one wire inside, then your money will continue to grow.
It is recommended that you look at figure above to understand thickness of wire tube, and then reasonably arrange number of wires. Anyway, master electrician recommends using 20 wire tubes, no more than 4 wires.
During construction, it is necessary to determine whether it will be installed open or hidden. Concealed installation does not affect appearance, but surface installation is convenient for later maintenance and replacement. During construction, pipe should be installed before threading. The number of lines in same pipe should not be too large to prevent replacement. It is impossible to pull old lines when. When hiding, pay attention to wall so that box body is 30 cm from ground.
The really accurate way would be to save time and waste building materials, and have a clear general layout drawing before starting construction. Never make temporary changes or solutions and keep line distance as short as possible. , save time and money with more peace of mind.
