DOMESTIC ELECTRICAL FAULT FINDING
Electrical faults at home can expose you and your family to great danger. And in some extreme cases, it may lead to a fire breakout if not controlled on time.
Hence, domestic fault finding in electrical circuits is an important aspect of maintaining electrical connections in the house. It is used to nip whatever fault there is in the bud before it becomes a full-blown issue.
Fault finding has to do with examining electrical connections to identify any fault it may have, isolate it and fix it. Whenever there is an electrical fault, the electrical circuit should be examined.
CAUSES OF ELECTRICAL FAULTS
Many things can cause an electrical fault in the home, office or anywhere electricity is in use. There are two major causes, which are; open circuit and short circuit.
Open circuit refers to a situation when there is a break in connection in electrical flow. It has to do with putting off a connection.
When you switch on the light, there is a closed circuit that allows electricity to flow, hence, powering the light on. However, the reverse is the case for an open circuit. When the light switch is put off and there is no electrical supply to power it on, then we have an open circuit.
A short circuit, on the other hand, has to do with when electric current flows in the wrong path. This then leads to the flow of excess current in a circuit. Cases like this must be taken care of to avoid electrical complications.
Some other common causes of electric faults in electrical circuits include loose connections, faulty connections, blown fuse, excess loads on electrical wires, etc.
TYPES/FORMS OF ELECTRICAL FAULTS
Some of the common forms/ types of electrical faults that occur in the home will be discussed in this section.
To begin with, we have electrical surges. These occur as a result of lighting, bad appliances, faulty wiring, etc.
Electrical surges occur briefly and do not last even up to two seconds. However, it is very important to know the specific cause and nip it in the bud. This is because electrical surges affect your electrical connections and weaken the life expectancy rate of your home appliances.
Another form of an electrical fault that must be found comes in the form of electrical shocks. This is usually caused by faulty wiring or by the appliance being plugged in.
To know where the problem stems from, you could plug another device into the switch that gives the electric shock. By so doing, you will know whether the fault is from the electrical wiring or the appliance plugged in.
However, you have to be very careful as this could be dangerous. You risk being shocked again. It is, therefore, best advisable that you get the help of a professional.
Circuit breaker tripping is also another form of electrical fault. This occurs when high wattage appliances are used on a single circuit. Hence, when a circuit breaker trips, it is signalling to you to check the appliances you are using on that particular circuit.
Circuit overload also occurs when multiple plugs are on a single socket and this would lead to electrical faults. The best way to handle this is to unplug devices that are not in use so as to reduce the workload on the circuit.
Other forms of electrical faults include light bulbs flickering, plug-in appliances not working, etc.
FINDING A FAULT IN AN ELECTRICAL CIRCUIT
Having examined some of the forms of electrical faults, it is important to state some tips and tricks that would help you detect electrical faults in your electric circuits and find a solution to them.
Getting the services of a professional would be of great help in many situations since an expert’s eyes and hands would do more thorough work than if you opt for a DIY. However, some tricks can still be applied to help you figure out the fault before professional work is done.
To start with, basic knowledge about electrical connections as well as having a wiring diagram would make the process of finding fault in an electrical circuit easy. This is because the diagram would show you the use of particular wiring and let you know what to do as you work on the electrical circuit in a bid to find out the issue.
Observation is also very important in the process of checking for electrical faults in electrical circuits. Physical evidence like loose wiring, blown fuse, the smell of wires burning, etc, should also signal where the problem might be from.
A Digital Volt-Ohm Meter (DVOM) would also be really helpful, in finding out faults in an electrical circuit.
REPAIRING FAULTY CIRCUIT BREAKERS
To start with, you need to put off the circuit breakers and the main switch for safety purposes. This is to make sure that the circuit breakers are isolated so as to prevent electrical accidents whilst working. Afterward, the main switch is put on and this helps to restore electricity into the house.
However, the sockets, individual appliances, and devices in the house are not yet powered since the individual circuit breakers are still off.
After this, the individual circuit breaker should be put on one after the other to detect which of them has the fault. You would discover the faulty circuit breaker when it trips off after being turned on.
Now, in a situation where all the circuit breakers trip off, it should be noted that this fault stems from the fuse box or earth source of electricity. This is a rare occurrence though; however, it is noteworthy.
Next, put off all the circuit breakers and start putting them on again except for the faulty circuit breaker. Then use this discovery to know the circuit breaker to repair when you call an electrician.
It is also important to check for the cause of the fault so as to prevent a re-occurrence of the situation in the future. The causes may vary including some of the causes we highlighted above.
