In our family life, Guangdong household wires are often used. Although it is very inconspicuous, the responsibility is significant. If the wire used by the residents is unreasonable or inferior, there is a risk of fire. Therefore, special attention should be paid to the selection and use. Next, I will share with you the experience of how to purchase wires, I hope to help you.
Wire specification
The specification of the wire is the line side - the cross-sectional area of ​​the wire, in square millimeters, referred to as square or square - this sentence has been reduced to two words "line".
The arrangement of the lines is leaping and there is no rule to follow. For example, there are 1 square wire, 1.5 square wire, but no 2 square wire; there are 2.5 square wires, but there are no 3 square and 3.5 square wires.
Fortunately, the line of household wires does not exceed 10 square meters, and there are only five kinds of wires within 10 square meters, so it is not difficult to remember: 1 square, 1.5 square, 2.5 square, 4 square, 6 square.
The thicker the line, the higher the current carrying capacity of the wire - the current carrying capacity of the wire determines the amount of current that can be passed through the circuit, so the key to our choice of wire is the current carrying capacity. When counting the current carrying capacity, you should not only focus on one socket, but should consider the operating current of all the sockets in the same circuit
