Finally, I began to prepare to put into practice my long-planned plan to upgrade the household outlet (in fact, I threatened it).
Generally, the old houses in Taiwan Province Province are not equipped with grounding wires, because they follow the Japanese architectural thinking.
In addition, many poor-quality sockets will not only provide poor-quality current after years of wear.
It will also lead to the socket heating and easy to fall off, and may even become the main cause of power accidents.
So I took advantage of the gap between the Chinese New Year to make a major renovation of all the sockets in the living room.
The materials used are the products of American socket manufacturers.
Cooper. AH5262W pure copper backplane industrial socket
What are the specifications? 125V 15A, suitable for Taiwan Province province 1 10V.
Cooper's unique patented five-claw structure makes the plug contact closely and not easy to loosen.
The male plug is not easy to be damaged, with longer service life and better contact area.
This can reduce unnecessary power consumption and extra resistance.
When using electrical appliances with high power consumption, such as vacuum cleaner or hair dryer, the socket is not easy to heat up.
The back plate is made of pure brass.
Other more advanced versions will have other special treatment, but this group in the demonstration is not so advanced.
The screws used to fix wires are covered with insulating plastic covers to prevent short circuit or electric shock.
The allowable wire diameter is 10- 14AWG (5.3mm square).
Screws for fixing the ground wire.
Cooper's sockets are grounded independently or not.
Buildings without independent grounding wires can be connected by pulling a copper wire around them and directly grounding the steel bars of the buildings.
Stamps that have passed the electrical inspection
Building supplies
First, prepare the necessary materials.
Besides the socket and screwdriver, the most important thing is the test pen.
Next, remove the socket trim panel.
Remove the screw
Then use the test pen to find the correct line of fire.
I'm not criticizing the bad plumbers in Taiwan Province Province, but I've met too many cases where the fire line and waterline are pulled indiscriminately.
According to the standard construction method, ~ ~ white is the ground wire and most of the live wires are red ... but this socket in the picture is not like this.
Therefore, it is strongly recommended that you test before construction. If the wire end in front of the socket is disconnected and then connected, you should try to change back to the correct color.
In order to let everyone know the color difference of wires, relevant information is specially posted.
Wiring color (meaning of special wire color)
1.？ Color line: used for equipment, electrical appliances or wiring system lines? What is the wire connected to the grounding electrode (ground wire)? Colored lines.
2. White wire: The grounding wire (neutral wire) used in single-phase three-wire power supply system is white wire, which is generally used for system grounding. In the three-phase three-wire or four-wire power supply system, the white line is set to S-phase, and the grounding line (neutral line) in the three-phase four-wire power supply system is also a white line. 3. Black wire: It is set as the first phase ungrounded wire (live wire) in the single-phase three-wire power supply system. In a three-phase, three-wire or four-wire power supply system, the black line is set to T-phase. In C.T. (than? ) wiring electricity? In, the conductor is a black line. 4. Red line: It is set as the second phase ungrounded conductor (live wire) in the single-phase three-wire power supply system. In a three-phase, three-wire or four-wire power supply system, the red line is set to R-phase. Power wiring? In, the conductor is red. 5.？ Color line: In three-phase, three-line or four-line power supply system, the black line T phase can also be replaced by blue line. 6. yellow line: in industrial wiring and handover? Control electricity? Yellow lines are generally used. 7. Other colors: except? The above colors are beyond the specific scope of use. Are wires of other colors in the same tube? In a multi-line environment, there are more? Distinguish control electricity? And increase the number of workers? Make love. Fire line l (oad): = > n(eutral):= line n (eutral) of general red and black wiring: = > general white wiring ground line g (circle): = >; It should be a green line.
Then go to the switchboard and turn off the switch. If you don't know which one it is, turn it all off.
In order to avoid electric shock (although it was open during construction, it took two pliers to get it all done)
The sockets in general houses in Taiwan Province Province are all long.
Pull out the wire with a screwdriver.
It is suggested that the oxidized part can be cut off before installing a new socket.
In addition, this installation art of plumbers in Taiwan Province Province is also very common = =
The place where the tap should be used is directly entangled with it.
?
Although I don't study electricity, I don't know if this connection has any influence or shortcomings.
But ... this will really look a little uncomfortable. ....
Because the new socket also has the function of faucet, it is all connected.
Then put the installed socket back.
Then lock the plaque and you're done.
Another reminder, Cooper's cover plate is divided into many versions.
This is the cheapest nylon sleeve. If you have a budget, you can also consider buying a metal cover.
It is said that it can isolate the interference of electromagnetic waves.
Here's a little discussion with you.
There must be many people who think that grounding must be done independently.
It's just that at present, most buildings with a little room age in Taiwan Province Province generally don't exist, but maybe buildings with relatively new room age will.
This product shared today is a non-independent grounding version, which can be used by ordinary families.
Because the iron boxes of sockets are mostly tied with steel bars.
In other words, the grounding of this socket can be directly connected to the socket iron box, and the steel bar can be regarded as grounding.
Although some people will say that this is not good.
But as long as you live in a house instead of a building, generally speaking, there will be no problem of being struck by lightning (the probability of being struck by lightning is lower than the probability of winning the lottery)
It should be more than enough to use.
At least after grounding, it will never be electrocuted by the computer host again! !
Is the socket in everyone's home prone to fever, looseness and poor contact?
Or are first-class enthusiasts already trying to transform power accessories?
It should be a good choice to spend a little money to upgrade the socket.
