tend to pull the wires

Add a new home appliances, tend to pull the wires , so that the current can follow the wires into the electrical safety . Guide wire is electricity . However, the choice inappropriately wire , electrical safety operations can not . Family usually by using wire as copper or aluminum core , wrapped in a layer or layers of the surface of the insulating sheath , called the insulated wire . With this layer "coat" , even if the lamp is lit , hand to touch the wire , it will not shock . According to the hardness of the wire core is not the same , the wire was divided into hard lines and soft  lines, soft plastic wire is made ​​from a plurality of thin copper wire foreskin for frequently mobile electrical devices, such as hanging lamp lamp cord and for iron, electric rice cookers power lines. However, in moist Mini HDMI cable  places, such as walls, use insulated wire to maintain the ceiling inside the insulated wire in general , the sets of steel or plastic casing to prevent rot and leak !
Wire laying methods and addresses are not the same, the choice is not the same as the thickness of the wire . In the kitchen room and high ambient temperature corresponding to the local selection of thicker wire , installed in the pipe to maintain them . Buy a new appliance , such as a lamp , microwave ovens , etc. , all with power from a cord and plug , you might want to pull a wire when exercising in a convenient local install a patch panel , if still use thin wires generally lamps on unsafe. If power 1000 watt microwave oven , washing machine 500 watts, 300 watts iron , with the  RAC CABLE use of these appliances , then add a few times current , time use a long, thin wire resistance, poor circulation currents will result in heat and burn the wire plastic "coat ." I usually see some wire charred black plastic sheath , which is the cause of excessive current .
Thus , the increase in home appliances, should check the wiring board had entered the house power wires and line thickness . Plastic wire "coat" is used to maintain the wire , to avoid leakage use, do not use wire , lead wire hanging wires , lights, or the wire wrapped around the handles of the lead wire . Because of this the easiest to wear the wire sheath formed leakage .
