Causes of light troubleshooting are often associated with cable damage. An electrician is usually invited to search for a cliff, but if there are some experience, it is possible to eliminate the electrical outfunction of the power grid.
Search for Wire Cliff Tester
The device is used to determine the break when the wire is open to access throughout the route. Disconnect the voltage in the distribution box area and on the wire. Cap isolation on the wires near the distribution box. Through the meter, make a second notch. Measure the cable resistance tester on this site. If the device shows a small resistance - there is no cliff on this site. Otherwise, after 1 meter, make the third notch and repeat the measurement on this site.
In the absence of resistance, make notches on a damaged area, performing them after 50 cm, and repeat the measurement of the resistance. Repeat operation until the length of the measured area remains within a few centimeters. Clean the damaged area from insulation, eliminate the malfunction and carefully insulate the wire in the seals. You can measure the resistance to the line of switches and sockets, then the length of suspicious areas is reduced.
Definition of a damaged section by contactless wiring indicator
The device can determine the location of the phase wire, responding to the change in the electromagnetic field. First, make sure that the phase wire is damaged. Take the indicator screwdriver, tap the contact or switch contacts tool. If the indicator glows when the phase wire is touched, it means that the zero wire is damaged, if not - phase. The wire in new homes is laid in the headquarters and plastered, outside the track is not visible. To determine the location of the wire on the wall it is best to use the wiring scheme. If there are no schemes, know that the wires are stacked by certain rules, strictly in the horizontal and vertical plane. Turns are made at an angle of 90 degrees. Find the junction box closest to the outlet or switch and drive the appliance from it along the wall. In place of the wire break, the indicator stops the beep. The device shows a wire break with an accuracy of 10-13 cm.
Elimination of cliff
Disconnect the voltage from the phase wire. With the help of a hammer and chisel, remove the plaster on both sides of the cliff, it is enough to clean 10-15 cm of the stages. Divide the torn ends of the wire to the side. Using a perforator and a special crown, perform a hole in the wall under the tank box. Install the box in the hole and lock the alabaster. Start the wire box. If there is a stock, connect the cut-off wires by colors and insulate the connector. Close the box with a lid. Strong shocktuch - you can feed the voltage on the wires.
Repair of zero wire
Disconnect the circuit circuit breaker. Disconnect the zero wire from the tire and connect the wire with the "phase" to it. Further work is similar to operations with phase wire.
Determination of the location of damage using the generator and the trail
The signal generator connects to the damaged wire. The second part of the device - the receiver - is conducted along the wall above the fine. Above the damaged area, the signal disappears.
The list of devices for determining the cliff of wires in inaccessible wires is quite large. For home use, it is better to purchase a combined device, for example, MS-48NS. He finds a cable in the wall, detects a phase and has other useful qualities.
