Thirty percent of households fire accident is due to the power wiring Four steps to teach you easy wiring

According to the ministry of public security, according to related survey data accumulated in a fire accident in recent 10 years in China, nearly thirty percent of the accident was due to causes such as power sockets, switches, circuit breaker short circuit, the first of all kinds of fire accident. If there is no naked optimism to face the disaster, to know it well household wiring is going on.

1, the switch

Quality first

In the household wiring system, switch socket is the most intuitive terminal access, is the first barrier household electricity safety. When the choose and buy, it is necessary to strictly the quality pass.

Hong Kong fly advice, switch when the choose and buy to see, touch, hear, ask. Look, look at the appearance of the product whether level off, without burr. Touch, with your index finger and thumb on the cover of diagonal, one finger, another you push hard on the finger, if loose covering, subsidence, have quality problem. Listen, toggle switch, switch panel voice more mild, feel more smooth product, the quality is better. , asked if it is made of high quality consulting switch conductive parts of phosphor bronze, silver contacts with composite.

On design, the traditional push button switch by life gradually longer wide plate switch instead. In particular, some with fluorescence of wide plate switch, without any increase in power consumption, on the basis of also avoid the dark night can't find the switch. In addition, with the dimmer knob switch panel has a tendency to application in the bedroom. But beware, dimmer switch cannot be used with energy-saving lamps, can only use ordinary light bulbs.

2, socket,

Pay attention to the function

Should pay attention to when choosing a socket outlet of copper is in line with the antioxidant (decrease caused by corrosion rust resistance and fever), strong toughness (maintain long-term use does not move), copper thickness () to reduce their resistance, less riveting (reduce fever) standard. Quality of the socket reeds should use pure red copper, reed thicker.

The choose and buy of outlet should be based on space varies from one of the function. Kitchen and toilet often have water and oil, had better use waterproof box or plastic board, effectively prevent short circuit caused by oil, water vapor intrusion. Families with children, with optional insurance against the safety of the socket, prevent children get an electric shock. Air conditioning, TV, microwave ovens, washing machines and other long-term electric appliances can use switch, socket, turn off the switch when not in use can reduce the standby power consumption. With the increase of household appliances power, such as electric water heater, electric heater, air conditioning and other electrical appliances don't use the traditional 10 a socket, had better use safer 16 a socket.

3, design circuit

Complete circuit diagram, do you understand?

Hong Kong fly advice, whether it is new, second-hand housing decoration, be sure to ask real estate developers or decorate a company to "complete circuit diagram", understand the home into the door line (into the family line is meters to the connection wire between the indoor distribution box, a few square millimeters, cross-sectional area of the wire is used to calculate the current size), help the household pattern changes in the future. Such as how to buy a air conditioning in the home, the original line is enough? The wall nail, will damage the dark bury trough and so on.

At present most open manufacturers will install 6 m ㎡ - 10 m ㎡ into line, into the line could not less than 6 m ㎡. Before decorating to know how much is currently in line path, house electric appliance total power consumption must be controlled within the range of limit, had better leave allowance, in order to add new electrical appliances product in the future.

Distribution circuit principle is according to the functional allocation: lighting, ordinary power socket, air conditioning outlet, such as kitchen, toilet power socket, should set up a separate circuits. Note that the high-power electrical appliances, such as electric water heater, air conditioning must adopt single loop, to work overtime often is the source of making fire.

4, weak current arrangement

Cable network is given priority to

So-called elv mainly refers to the TV, telephone, Internet and other circuits, dc voltage generally within 32 v. Weak current and high voltage difference: high voltage is used as a kind of power energy, weak current is used for information transfer. First of all, weak current decorate should stay away from the high voltage. Because of the high voltage heavy current, easy to produce electromagnetic interference, with low voltage circuit together affect the weak current signal.

When decorating, had better be in sitting room, bedroom each have telephone port, to prevent the occurrence of failure phone can't use a route. Application network, although the present wireless network has been widely applied, but considering the privacy and online banking transaction security problems, suggest using wired Internet access in the home is given priority to, wireless Internet access is complementary, therefore in the different space should have Internet cable port, convenient for daily use. Digital TV port within a general application in the sitting room, bedroom, advice on TV wall for a network port, convenient after watching IPTV.

The Suggestion

1. The switch fabric?

Switch the location of the average distance from the ground 1.3 m to 1.4 m, children room in 1.2 m to 1.3 m, if two switches and installation, the error between them should not be more than 5 mm. 2. The socket how to meet?

Before to decorate, must consider each space socket layout. General electric power cord length is 1.5 m to 2 m, so every 4 m leave a socket is more convenient. In general, the number of indoor outlet can per 2 ㎡ in 1 set of panels (a switch, a socket) to calculate. If indoor area is 100 ㎡, assemble 50 group panel can basically meet the demand of daily life.

3. The circuit design?

Different circuits and electrical requirements for the path of the circuit is different. According to the regulations of the state, the family is decorated in, lighting, switch, socket with a 2.5 m ㎡ wire, air conditioning to use 4 m ㎡.

Scheme configuration

1.5 m ㎡ lighting (use the 2.5 m ㎡ line more than 800 w)

Ordinary power socket 2.5 m ㎡

Air conditioning socket Wall hung a single loop optional 2.5 m ㎡

Wall more appropriate circuit chooses 4 m ㎡ or above

Floor air conditioning circuit appropriate chooses 4 m ㎡

The kitchen loop 4 m ㎡

   Wiring Q&A

   Q1: copper wire quality is better?

A1: conductor is common material are mainly copper, aluminum, lead, iron, etc. Among them, the copper wire is considered to be the best conductor carrier, the national standard specifications for design of residential GB50096 mandatory, "lead wire" should be adopted. Copper wire, though the price a little expensive, its resistivity is small. In the chemical elements on the periodic table, the conductivity of the copper after mercury, silver, platinum and gold. High conductivity reduces power consumption, to avoid the wire fever caused by short circuit, fire and other hazards.

Q2: how to reasonably select light source?

A2: at present there are: light source is commonly used in household incandescent lamp, fluorescent lamp and energy-saving lamp. Energy-saving lamps is country promotes the use of light source, can effectively save power, but does not apply to the dimmer switch. Fluorescent lamp luminous efficiency is high, service life in 2000-3000 hours. Incandescent lamp luminous efficiency is low, service life in 1000 hours. Most of the space, it is better use light when two exceptions, but the kitchen kitchen use incandescent color rendering index Ra value is higher.

Q3: how to control the same lamp in different places?

A3: through the wiring in advance, to double the switch control function design, can easily implement different place to control the same lamp. For example: the bedroom to the bathroom need to go through the sitting room, can design the bedside switch control sitting room lighting; If the bedroom is not far from the bathroom, bedside switch can be used to control the bedroom lighting.

Q4: which place is suitable for the anchor socket?

A4: anchor socket generally suitable for larger living room or restaurant. For example: sofa without walls, can consider to install on the ground anchor socket; Table below can install the anchor socket, to facilitate the use of appliances such as hot pot.
