If you don't pay attention to the specifications of the wire, the wire is indeed thicker than the thinner, because the thicker the wire, the greater the continuous current carrying capacity, the better the insulation of the wire, and the safer it is to use.
However, if the usage of the place of use is included, it is not enough to pay attention to the current carrying capacity of the wire. For example, what we are talking about now, "home-made wires", in addition to considering wires, we also need to factor in all aspects. In the decoration environment, the thickness of the wire changes, which will cause the following two drawbacks:
Increased renovation costs
Calculated alone, 6 square copper wires do not seem to be much more expensive than 4 square copper wires. However, the number of wires used increases, which will also cause a series of increases in decoration costs.
The wire has been increased from the original side, and the corresponding threading pipe must also become thicker; the depth of the wire groove must be increased; the depth of the landfill must be increased; the size of the pipe clamp must be increased; and the construction period must also be extended. Plus-and this is just a matter of cost, as well as other incidental losses.
Reduced operability
The thicker the wire, the greater the difficulty of construction-in addition to the difficulty of threading the trough and backfilling the trough, there are also difficulties in construction, installation and maintenance. And the wire becomes thicker at the same time the hardness also increases, threading takes time and effort, and it is easy to appear dead.
In fact, which one is suitable for the home improvement wire is just like buying shoes for yourself-it is not good to be too big or too small, and the best is the best!
In the decoration design that is more in line with the current household electricity demand, there are clear provisions: 60 square meters (inclusive) or less construction area, 6 square copper wires are used for household wires in home improvement wires; 1.5 square copper wires are used for household lighting; ordinary electrical outlets Use 2.5 square copper wires; use 4 square copper wires for high-power sockets such as air conditioners and ovens.
For a 60 square meter residence, use 10 square copper wires on the household line; 2.5 square copper wires are used for ordinary household lighting and general electrical outlets; 4 square copper wires are used for high-power outlets such as water heaters and air conditioners.
