Electrical Fault Finding Techniques

When it comes to fault finding in electronic circuits, you will need to have some understanding of basic faults and electrical diagrams. If you don’t, then you will need to engage a professional to help you.

Electrical faults cover any issue in your circuits that cause your electrics to surge or trip and can become dangerous if they are not resolved. Understanding electrical diagrams can be a challenge because electrical circuits include components such as:

  • Fuses
  • Switches
  • Lights
  • Breakers
  • Motors
  • Pumps
  • Relay
  • Fans
  • And more

The first thing you will need to do when it comes to understanding a home fault is to check each component is working correctly. The most common issue tends to be when connections have become loose when fuses have blown or when there are faulty connections, relays or sensors. Before you can begin to test house electricals, then you will need to complete a visual check to see if you can locate the source of the problem.

Using Specialised Kit

Using equipment like a DVOM will help you to find your electrical circuit problem quickly as it checks the amps, volts, continuity and resistance as well as being able to test your lights for any specific voltage drops. 

The Wiggle Test

If you find that your fault seems to come and go then the best way to work out the source is to wiggle the wires and see if the fault happens. This can take some time if you don’t first try to work out the source of the problem, so it is sensible to check things thoroughly first. If the fault does occur when you wiggle the wires, then you can be confident that the issue comes down to a broken, dirty or damaged connection that will need to be replaced.

Finding Electrical Faults

Many people find electrical fault finding frustrating because it requires a good level of electrical knowledge and patience. However, to make it slightly easier, you should bear in mind that most electrical issues are caused by one of the following electrical circuit problems:

Open Circuits

An open circuit problem arises when an electrical connection breaks. This means that you will need to know how to test for broken wire issues in order to address the issue. To be about to do this, you will need to implement the continuity test.

Short Circuits

If the electrical flow is changed and diverts to a different path, then you will get a short circuit. These can be dangerous and result in fire or damage to your home. If you want to test house electrical circuits, you will need to check the resistance and difference in the electrical current flow between two points.

Continuity Problems and Continuity Testing

If you need to test your circuit’s continuity, you will need to use a multi-meter that will beep if the path is complete and functional. If the path is faulty and not working, then there will be no beep, and you will have located your issue.

How You Can Solve Electrical Faults With Ease

Completing these tests at home can be dangerous if you do not have the right knowledge or experience. If you are worried about any of your equipment, then it is a good time to call in the expert electricians to help.
