How to detect short circuit in home circuit, it is very simple to detect electrical short circuit with multimeter
When there is a short circuit in the home line, as long as the electrical appliance is running, it will trip. Unless the short-circuit point is found and the fault is eliminated, the line will be normal. Here is a simple method for a multimeter to detect electrical short-circuit.
Multimeter to check whether the electrical appliance is open circuit
1. Multimeter detects short circuit
Use the resistance gear of the multimeter to measure the resistance value between the lines, disconnect the power supply, disconnect all loads in the circuit, including light bulbs, TVs, washing machines, refrigerators, etc., use the resistance gear of the multimeter to measure the live wire and the zero wire, if the needle goes to the scale More than 1/3, it means that there is a short circuit.
2. Decompose the circuit in turn
Disassemble the wiring first, and then use a multimeter to check whether there is a short circuit in the home circuit.
Detection method: in the middle of the line at home, untie the wire, measure the first half of the circuit and the second half of the circuit separately, to make a division of the possible location of the short circuit, see if the short circuit is in the front or the rear, and then untie it in turn Part of the circuit, check step by step until the fault location of the short circuit is found.

3. Simple way to detect short circuit
Hit the multimeter to the place where there is one less line in the sign like "month", when the buzzer makes a beep, it means a short circuit, if there is no sound, it means the line is normal.
In addition, you can also put the meter on the resistance gear. When the resistance value jumps out, it means that there is a short circuit in the line. If the displayed value is 1, it means that there is no short circuit.
The above is the method of using a multimeter to detect whether the home circuit is short-circuited. I hope it will be helpful to everyone.
