Leakage current is an important concept to understand when dealing with electrical systems. It refers to the small amount of electric current that flows unintentionally through a conductor or insulation, which is supposed to be non-conductive. In other words, it is the current that “leaks” from its intended path and finds an alternative route to flow. Leakage current can pose various risks, such as electric shock and potential damage to the equipment or devices connected to the electrical network.
It is crucial to regularly check for leakage current in your home to ensure the safety and functionality of your electrical system. This introductory guide will explain what leakage current is, provide an overview of how to check for leaky current, and offer some methods to fix it at home. By the end of this article, you will have a better understanding of this phenomenon and be equipped with the knowledge to address any leakage current issues that may arise.
Many families use electricity but still do not understand about leakage current or how to handle leakage current? To be safe in the process of using electricity, let’s learn the concept of leakage current, how to check and fix leaky current at home below!
What is leakage current?
Leakage current is a physical phenomenon that often occurs in electrical equipment. It wastes and excesses electrical energy, then transfers this energy outside the device housing and causes unexpected accidents and problems.
The main cause of power leakage
The electrical equipment you are using is too old
This will easily happen when you use too old equipment. An electrical device, when used for a long time, will lead to the state of the internal circuits and microchips being corroded, giving off high heat, creating conditions for leakage currents to appear.
Electrical equipment you put too close to the wall, near a wet place
The surrounding environment is also the main cause of leakage currents. If you place the device in a humid place, it will create conditions for high temperature as well as air humidity, making the device’s electrical cord degraded and many days will lead to more severe leakage.
Incorrect installation technique
During electrical use and repair, disassembly of equipment, parts and components will upset their positions, resulting in incorrect installation of electrical circuits. This renders electrical equipment inoperable and leads to leakage currents.
Due to external factors
Some external factors also cause leakage currents to appear, such as components being bitten by insects or rats. Since it occurs inside electrical equipment, it is very difficult to test and detect leakage currents.
How to check leakage current at home
Electric leakage pen
Electric leakage pen is considered the fastest and simplest way to check. You just need to use this pen to probe on the surfaces with underground current, if the light of the pen glows red somewhere, there will be a leakage current and need to be repaired immediately.
Check for electrical leakage with a multimeter
To be able to do this, you must make sure you understand the parameters and what they mean on the meter. Currently, there are many different types of multimeters, you should choose which type of meter is capable of testing leakage current to be able to use it.
Use clamp amps
Currently, the tool most used by electricians is the clamp meter. With a compact, convenient structure, it is easy to carry but produces results with high accuracy. You only need a little understanding of the parameters on the device to be able to use it to check leakage current.
How to fix electric leakage problem
Troubleshooting electrical leakage will be simple if you understand the process, but it is also very dangerous if you do not ensure protection problems. You need to wear shoes and sandals to avoid the grounding current and causing danger to you. You can perform the test by following these steps:
Step 1: Determine the location of the leakage by disconnecting the main circuit breaker, then zoning the range of leakage currents by seeing at that range, whether the electricity meter rotates or not, if not, it means the area that leaked.
Step 2: Unplug all electrical equipment (washing machine, refrigerator, …) in the area of leakage and conduct timely inspection and repair.
Step 3: Turn the power meter back on and check if the devices are working properly again.

In conclusion, leakage current refers to the unintentional flow of electric current from a conductor to the ground or another conductor, resulting in potential safety hazards and energy wastage. It can occur due to various reasons such as insulation breakdown, faulty appliances, or improper wiring.
To check for leakage current at home, you can use a device called a leakage current tester or a multimeter set to measure AC current. By following the manufacturer’s instructions, you can identify and measure the leakage current in your electrical system.
Fixing leaky current at home depends on the cause of the leakage. If it is due to faulty appliances, it is best to replace or repair them. For insulation breakdown, hiring a professional electrician is recommended as they can locate and repair the faulty connections or replace damaged insulation.
Some preventive measures to reduce leakage current include ensuring proper installation of electrical appliances, using surge protectors, regularly maintaining and checking electrical systems, and avoiding overloading circuits. It is vital to prioritize safety and address leakage current promptly to minimize risks of electrical shocks, fires, or damage to electrical equipment. If in doubt, it is always advisable to consult a professional electrician for assistance.
