How do you find a cut wire?
Make sure the leads are connected to metal in order for the multimeter to work properly. If the resistance is zero, you’ve found the break. If the resistance isn’t zero, continue searching along the cord until you get a zero reading. The zero reading is the indicator of a broken wire.
How do you make a broken wire detector?
Take a short length wire as antenna and connect it to the base terminal of Q1 transistor, this Q1 transistor biased through 100KΩ Resistor and emitter terminal connected to Base of Q2 transistor this is biased through 10KΩ Resistor then emitter terminal of Q2 is connected to the base of Q3 transistor, Buzzer and LED …
What to do if you cut through an electric cable?
If you suspect that an electric cable has been hit, it is absolutely necessary to repair it. You should immediately ensure that the power is switched off before touching anything. In the worst case, if the protective earth conductor has been damaged you otherwise run the risk of a fatal electric shock.
How does a broken wire detector work?
It detects the broken wire by detecting the presence of AC voltage in the wire. When there will be AC voltage present near it, then it will start beeping and LED will go high while when there will be no AC voltage or if there will be a broken wire, then the buzzer will remain quiet and the LED will go low.

How do you remove insulation from electrical cable?
Use a wire stripper to remove about 1/2 inch of this insulation from each wire. The stripper tool has slots to match various wire gauges; use the slot that matches the wires in your cable. Check the wiring on both cables for any sign of damage, such as cut, chewed, or burned insulation or nicked wiring.
How big should the sheathing be on a circuit box?
The cable sheathing should extend past the clamp into the box by 1/4 to 1/2 inch. Tighten the screws on the clamp until the cable is securely gripped.
