What Are The Steps To Fault Finding?

If your electrical appliance is malfunctioning, you can detect it straight away. But, detecting a fault in your central electric line is a different story altogether.


Maintenance is the topmost priority for your electrical system because no one wants to spend hundreds of dollars on repairing electrical damage. Timely detection of an electrical fault can help you save hours of work and tons of money.


But it’s easier said than done. Even well-experienced electricians might struggle to locate the exact fault in your electrical lines at times without a proper action plan.


We’re here to discuss a detailed approach to detecting any electrical fault that’ll help you take immediate action. This guide highlights six key steps to fault finding that focus on locating and analyzing the root cause of an electrical fault to rectify it.




1. Collect Evidence 

The first and foremost step to electrical fault finding is to collect all the relevant evidence that’s available at hand. If you are not sure whether the evidence is relevant or not, the best course of action is to include it. After a more thorough examination, you can always eliminate it if it’s not needed.


Remember, the quantity of information you collect is not important as long as you examine its relevance. Closely check all the electrical systems that are running by adhering to safety protocols and applying your senses. Try to determine a burning smell or use your hearing to check for any unexplained vibration of your electrical appliances.


Also, touch the appliances to check their temperature and watch out for electrical sparks. It’s always best to have some relevant documentation that you can refer to while collecting the evidence.


2. Analyse The Evidence

Once you’ve collected all the evidence, it’s time to analyze them to narrow down the electrical fault diagnosis. This is the step where you can reject any evidence if you think it is not relevant to the case after a thorough analysis.


Use relevant documents as your reference and apply your logical thinking while analyzing the collected evidence. In that way, you can determine the region or area of the electrical fault.


3. Locate The Electrical Fault 

Locating the electrical fault is essentially the extension of the analysis step where you systematically reduce the size of the area to pinpoint the exact location of the fault. You can do this by considering all available evidence and studying them carefully.


For instance, if your food mixer isn’t working properly, you’ll first check the appliance by plugging it into a different power outlet. If the mixer is working perfectly in other power outlets, the machine is fine, but the problem lies with the electric line of the wall socket in your kitchen.


In any case, you have to locate the exact area of the electrical fault by following a logical process of elimination. This way you can determine whether you have a faulty electrical line or the electrical appliance is simply acting out.


4. Determine The Cause And Remove It 

Whenever you’ve detected an electrical fault, you need to determine the root cause of the problem. If you can’t identify the primary cause, the fault will continuously recur, even after you rectify it.


Say you’re suffering from fever; you can take some medications to treat it and get better. But, if you can’t identify the cause of the fever, no matter how many medicines you take, it will keep on coming back.


Similarly, once you determine the cause behind the electrical fault, like old electrical wires or sudden power surges, and remove it, you can permanently rectify the fault. It’s best to hire professional electricians who can apply their knowledge and expertise to determine the cause and fix it correctly.


5. Rectify The Fault 

Depending on the intensity of your electrical fault, the complexity of rectifying it will vary. If you have a small electrical fault in the doorbell featuring a busted power socket, you can just replace it with a new one. You might not even need to hire any professional for small electrical faults and take care of them all by yourself.


But if you face major electrical faults due to old electrical wirings, you need to contact professional electricians as soon as possible. They use their advanced equipment to change the worn-out wires and rectify the fault to avoid any long-term electrical damage. Also, never try to change old electrical wires by yourself.


6. Check The System 

Once the electrical fault has been resolved, you should always check whether the entire system is working properly or not. Check your electrical appliances and the power outlets to make sure that they are running smoothly. And be careful about sudden power surges to avoid any future electrical faults.


If you hire professional electricians, they can use their expertise to fine-tune the system. They can also determine whether the electrical fault has been rectified properly or needs more work.




We come to the end of our informative guide on how to detect and resolve electrical faults. When it comes to electrical fault finding, it’s always best to follow a systematic approach based on collecting evidence, analysis, and logical thinking.


After going through our article, we hope you have a better understanding of the six-stepped logical approach to fault finding. Simply follow the methods we’ve mentioned above, and you can maintain all the electrical systems in good condition for years to come. And if you hire professional electricians, they’ll take care of everything for you without any hassle.


Most importantly, don’t forget to conduct regular maintenance rather than waiting for a problem to occur before calling a certified electrician. You should never take your family’s safety for granted, so stay vigilant.


It’s time for us to say goodbye. Until next time!
