When renovating, hydroelectric retrofit is very important. If the wire specifications are not selected correctly, there may be insufficient number of sockets in the subsequent use process.
In general, there are five types of household wire specifications, which are 1.5 square meters, 2.5 square meters, 4 square meters, 6 square meters and 10 square meters.
I specifically asked the electrician if the wire was as thick as possible. His answer to me was this: "The thicker the wire, the better, but it is enough to choose a 6 square wire at home." "So how to choose the specifications of home improvement wires? Let me tell you!
Is the thicker the wire, the better?
If you ask the master electrician this question, it is estimated that everyone will answer you "Yes, the thicker the wire, the better." ”
Why?
Home improvement wires are generally available in five sizes, 1.5 square meters, 2.5 square meters, 4 square meters, 6 square meters and 10 square meters.
The thicker the wire, the greater the ampacity, the thicker the insulation layer, and the better the flame retardant effect. That said, the thicker the wire, the more wires can drive more wires, and the risk of fire is not so high.
Increases the difficulty of cabling
Obviously, the thicker the wire, the better, why do some people say that if you can use 6 square meters, you don't have to use 10 square meters?
I think it's mainly because the wires are too thick, which makes it harder to route.
The depth and width of the thick wire slots must be increased, not only that, the thicker the wire, the harder it is, and the difficulty of passing through the pipe will be greatly increased.
If subsequent repairs are needed, it is not easy to pull the wire out of the conduit.
There will be an increase in fees
Choosing thick wires, the second obvious disadvantage is that it will increase the cost.
Thick wires will cost two more than thin wires, the first being the cost of wires. The thicker the wire, the more expensive it is, and the unit price of a 10-square-meter wire is definitely more expensive than a 1.5-square-meter wire.
The second cost is the cost of the conduit, for example, 16 pipes can wear 3 4 square wires, but only one 6 square wire.
It doesn't work
Choosing a thick wire may not necessarily achieve the desired effect.
Generally speaking, the switch of the meter box and the distribution box will limit the maximum electricity consumption in the home, even if you install 10 square meters of wires in the whole house, there is no corresponding current, and it cannot reach the effect of 10 square wires.
What specifications to choose for home improvement wires?
Having said all this, what specifications are the most suitable for home improvement wires? I can only say that the wires in different areas are also very different in specification.
It is enough to select 1.5 square meters for the switch wires, and 2.5 square meters for the sockets and lighting wires.
High-power appliances, like water heaters, hoods to choose 4 square wires are completely sufficient.
There is one exception in the appliance, and that is the air conditioner. 220v, 5000w air conditioner is recommended to choose 6 square wire, 380v, 5000w air conditioner choose 2.5 square wire is enough.
Well, around the wire is not thicker the better to make a detailed elaboration, the following I will summarize it:
Home improvement wires should not exceed 6 square meters, because the thicker the wire, the more troublesome it is to install, the higher the price, and the most important thing is that it does not achieve the expected effect.
