(1) Install the line as required. The installation of electrical wiring must be in strict accordance with the electrical installation regulations, and a dedicated electrician should be required to lay the line. The electrician must be certified to work.
(2) Select the correct electrical circuit. According to the actual needs in the work and life, the load may be selected to the appropriate size of the electrical circuit, not to use thin or inferior wires for the sake of greed.
When selecting the wire, pay attention to check if it is a qualified product.
(3) Safe use of electrical circuits. The installed electrical circuit can not be pulled, connected, or used indiscriminately, increasing the power load of the entire line. Pay attention to the maximum load of the circuit used, and do not exceed this limit during use, otherwise it will cause accidents.
(4) Always check electrical wiring. It is necessary to insist on regular inspections. At regular intervals, please ask a special electrician to help inspect the electrical circuit and find that the insulation layer is damaged and repair it in time. The service life of the wire is generally 10 to 20 years, and it is necessary to replace it in time.
(5) Select a safe electrical switch. To use an air switch with a high safety factor, try not to use the knife switch. The knife switch generates an electric spark when it is switched, which is dangerous. The use of an air switch can cut off the power protection. When using a fuse, choose a suitable fuse to avoid malfunction. When the current increases, the current can be cut off in time.
