What are the misconceptions in installing household electrical wires?
Water and electricity engineering is the most worrisome aspect of renovating a new house, especially electrical wiring. Nowadays, there are many household appliances with high power. If there are any problems with the quality or installation of electrical wiring, a small piece of electrical wiring can instantly become a killer of family safety. So, let me tell you what are the misconceptions in installing electrical wiring for household appliances!
Mistake 1: Strong and weak current co management
AC power is commonly used in Chinese households. Some construction teams, for the convenience of construction, directly store all electrical wires together, such as power cables, network cables, telephone cables, etc. This can cause interference between lines, leading to unstable signals. It can also become a hidden danger in home fires. Strong and weak currents should be routed separately, and it is strictly prohibited for strong and weak currents to share a single tube or bottom box.
Myth 2: Repeated wiring
Some construction workers use a pipeline for each wire to make the pipeline look clearer, which results in many pipes buried inside the wall. When repairing in the future, it is difficult to locate the location of the problem pipeline, or most of the structure between the wall and ground must be damaged in order to find the problem point. Generally speaking, the line should be made into a "live line", and wires in the same direction should be placed in a single pipe without exceeding 40% of the pipeline capacity. This is both economical and avoids the trouble of future maintenance.
Mistake 3: Directly burying wires without casing
Some irresponsible construction companies bury wires directly into the wall during construction, but the wires are not properly insulated and the wire joints are exposed, which can easily cause safety hazards and is a typical phenomenon of cutting corners. In future life, wires lack protection and are prone to being bitten by mice or external damage, leading to short circuits in the wires. The laying standards for wires are clear, and there must be insulation sleeves outside the wires for protection, and the joints cannot be exposed. Therefore, everyone must pay attention during the construction process.
Myth 4: Arbitrary installation of socket wires
The power wire must use a copper wire cross-section. If you live in an old house, you must replace the original aluminum wire with copper wire. Because aluminum wires are prone to oxidation, the joints are prone to sparking. In addition, many families adopt the method of slotting, burying wires, and laying concealed pipes for the sake of aesthetics. When wiring, it is necessary to follow the principle of "live wire enters the switch, zero wire enters the lamp head", and leakage protection devices should be installed on the sockets.
