finding home wiring fault

finding home wiring fault – How to repair electrical wiring in a house , an apartment , find damage etc.

With an electric shock, do not joke , so use these tips only when the situation is urgent , especially if you ” electrician ” beginner. But in any case , knowledge is almost never are not redundant (if this knowledge themselves right ) and a few of these simple tips will help you to quickly rectify the situation when a call a professional electrician is not possible for any reason .

To own my own hands to find and fix the fault in the wiring , you need to keep calm and act consistently .

Consider the most typical cases .

If damage is visible wiring
Place damage wiring installed : puffed appliance , appliances , in sockets, switches, junction box ( RK) was a flash , detected the smell of burning insulation.

What, where, how?

The first de-energize the entire apartment (if this does not happen automatically when blown fuse or tripped input automata ) – Remove the plug or turn off the machines .

A damaged appliance simply unplug the power , then turn it on again machines ( replace fuses in the fuse-link ) .

Victim outlet ( switch) unpack and inspect . Faults they appear mostly due to poor contact in the joints – on load occurs excessive heat , melt the insulation and eventually circuit or wire breakage .

If the short circuit is not damaged internal “organs ” of the device , it is truncated ( stripping ) charred end of the wire , its performance can be restored.

which are usually located under the ceiling flush with outlets or switches may be two : bad contact or a small section of the wires.

After removing the cover , straighten the wire , pulling them over a pair of pliers .

The box will be a few twists . Two very thick (at three-wire cable of three ) are the main – this phase and neutral . Stranding with fewer wires – more , they go to the lighting. Usually burn wires , suitable for main -twisting.

Carefully inspect the wires melted . If the damage is only isolation , knife carefully separate the wires in the cable apart and insulate each individually .

If both or some wire bad , add a piece of the desired length using a twisting or pads ( terminals) .

If the place where the burnt wires are not visible

The fault location is unknown: burnt cork or worked machines, but apparently not as a result of overloading.

Case is less dangerous but more troublesome , because added to the problem of finding fault .

What, where, how?

Pulling out of the socket , turn off all the equipment from the mains and turn off the light .

Turn machines or change the plugs ( with no backup can be done “bugs” out of thin wires that are woven into a household cords ) .

Embossed cork disabled Automatic will mean that faulty wiring, and not some of the appliances or lighting.

Wiring should be checked with the endpoints , ie with sockets: disassemble , inspect , shorted wires , etc.

If there is damage repair them , and then turn the power back .

If the protection is still activated , open the RK – short circuit appears as a melting or blackening isolation.

iron Rules

Use indicator to check the voltage .
Use only insulated ‘supplies .
Do not repair in the dark with a flashlight .
Note:

99% wiring faults occur at joints and connections , so do not rush to break open the wall or plaster.
In 9 cases of damage to the cable 10 directly to the wall occurs as a result of drilling, hammering nails , etc.
