Misunderstanding 1: The socket location is too low. Many households feel that they are too tall and unsightly when installing sockets, and they will be installed in lower hidden places. This makes it easy to splash water into the socket when the floor is mopped, resulting in electrical leakage. The industry stipulates that it is better to have a wall-mounted socket not less than 1.5 meters from the ground, and a concealed socket no less than 0.3 meters from the ground. The socket of the kitchen and toilet should be more than 1 meter above the ground, and the outlet of the air conditioning hook should be at least 2 meters.
Misunderstanding 2: The outlet wires are installed arbitrarily. Power conductors must use a copper cross-section. If you live in an old house, you must replace the original aluminum wire with a copper wire. Because the aluminum wire is easily oxidized, it is easy to light the joint. There have been investigations showing that the incidence of electrical fires in residential buildings using aluminum wires is several dozen times that of copper wires. In addition, many families will adopt slotted embedding and dark pipe laying for aesthetic reasons. I reminded that when wiring, we must follow the principle of “into the fire line, zero line into the lamp†principle, but also set leakage protection in the strong box Device.
Misunderstanding 3: The outlet lacks protective measures. Water and soot are often found in kitchens and bathrooms. Therefore, it is best to install splash-proof boxes or plastic baffles on the socket panel, which can effectively prevent short circuits caused by oil and water vapor intrusion. For families with children, to prevent children from touching with their fingers or metal objects, use a safety socket with a safety flap.
In addition, some decoration companies often make ground wires void when installing three-hole sockets, and even directly connect the ground wires to gas pipelines. These practices are very dangerous. The ground wire is connected to the housing of the appliance. Once the appliance is leaking, it will cause people to get an electric shock.
Misunderstanding 4: Multiple appliances share the same socket. This will overload the appliance and cause a fire. Air-conditioning, washing machines, range hoods and other high-power appliances are best to use a separate outlet. In general, it is best to install a set of sockets in the bedroom, a group in the living room, and a kitchen.
Myth 5: There is only one loop. There is only one circuit in the old house. Once any circuit is short-circuited, the electricity in the entire room will be paralysed. In general, the socket can choose 3`~~4 loops, and the kitchen and toilet can all go all the way. The air conditioning uses 3~~4 loops.

A typical version of an overhead garage door used in the past would have been built as a one-piece panel.The panel was mounted on each side with unequal parallelogram style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers. The door is balanced by either a torsion spring system or a pair of extension springs.A remote controlled motorized mechanism for opening garage doors adds convenience, safety, and security
• Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductivematerial.
• Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
• Steel doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).
• Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.
