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.

In conclusion, it is important to be vigilant to detect electrical faults in circuits and lighting and repair them in time.

What is a CCTV?

CCTV, fully known as Closed Circuit Television, is a security camera used in the interior and exterior parts of homes, offices, public places, etc to monitor the movements of people and things in the facility for security purposes.

It is an efficient means of keeping a place secure through cameras that capture the happenings wherever they are fixed.

CCTV helps to capture live events, which are currently taking place. It also keeps past events in form of video footage which can be referred to for future purposes.

How much is the cost of a CCTV?

In choosing a CCTV for your home, various factors determine the type to be purchased.

Some of these factors include; the location where it would be placed in the building, how the CCTV would be powered, how it would be connected to the internet, how it records etc.

The cost of one home CCTV system, with monitor, DVR recorder, monitor, wiring, and full installation would be around £540 – £660.

However, some CCTV cameras may cost a little more or lesser than that depending on the features they possess.

Hence, it is best to focus on the benefits you wish to derive from the CCTV and purchase one that fulfils that desire.

CCTV and Security System

Now, in keeping your home and office area secure, you have the choice of either using a CCTV or a wholesome security system.

A security system refers to a group of interconnected security devices such as sensors, windows, and other gadgets that are fused and monitored by a central control – usually your phone.

In using a security system, you would have to request a certificate to have it installed. Also, it costs more money since it would be professionally monitored.

However, it helps more with security as you get notifications on your device to alert you of happenings on your property. It also automatically alerts the police in situations of a breach of access.

Now, a CCTV is a DIY security type that you install by yourself in your home. However, you won’t be able to always monitor the activities going on except you are always watching it. And the probability of this happening can be quite low.

Also, when something goes wrong, you have to alert the security agencies yourself.

Nevertheless, CCTV is a very useful instrument in capturing criminals while they carried out their criminal activities.

The video footage from its recording is used as an irrefutable form of evidence to prove a point in situations where there is a lawsuit.

CCTV or Alarm

One dilemma that people find themselves in is choosing between an alarm and a CCTV.

An alarm is a security system that alerts you of intrusion on your property. The alarm helps to warn and wade off intruders when it goes off. It also alerts you as well.

Now, you necessarily do not have to choose between them. You can use both and harness the features available in them to secure your home.

CCTV and Access Control System

Asides from using alarms with your CCTV, or not using it, as you may deem fit, another form of security system that can be integrated alongside a CCTV is called an Access Control.

Access Control is a form of security that restricts the people who have access to a building.

It is used to prevent unauthorised access into a building, thereby, protecting the people and properties from external attacks.

Access Control is usually issued to the legitimate occupants of a facility such as house owners, tenants, workers in an office space, etc, through an access control card. This card is presented to a card reader to grant the holder access.

Therefore, in a situation where there is an intruder, a forced attempt would be made to enter the building. But since no card would be presented in this case, the alarm goes off alerting the owners that there is an intrusion.

And in the situation of an intruder using a stolen or lost card, the access control can be configured in such a way as to detect whether it is the legitimate owner of the card using it or not.

The security of a home is more ensured when CCTV is integrated with access control. This is because one could easily watch the video footage from the CCTV to know what the problem is when the Access Control Alarm goes off.

This provides a two-way security feature that safeguards oneself and one’s property because the access control would alert one of danger. The CCTV would be checked to know who the intruder is. It can as well be used as an undeniable form of evidence in a lawsuit.

CCTV – Wired vs Wireless

There are various kinds of CCTV connections. There is the wired and wireless CCTV and each has its pros and cons.

A wireless CCTV refers to one which is connected to the internet via wifi. Some wireless CCTV can be powered by themselves without being plugged into a power source as they make use of batteries to generate power.

However, in using wireless CCTV, there are still some disadvantages.

One of them is that during the broadcast of the video, the quality of the image is intentionally reduced to make the video stream faster and so as not to lose any important detail in the footage.

However, for a wired CCTV, the video is transmitted with high quality without losing any part.

How to install a CCTV?

So how do you install a CCTV camera in your home, office, or anywhere? It is a pretty easy process and you would be taken through some steps to help you set up your CCTV today!

  • To start with, it is important to choose the right spots from which the video coverage would be fully maximised.
  • Inside the house, the camera should be placed in a corner from which it would capture movements around the entrance and exit of the house. And for the outdoor space, it should be placed in a high position where it would cover activities going on outside the house. These locations include the garage, home entrance, window area, etc.
  • Afterwards, the next step is to fix the camera in the desired area, and drill it into the wall with a screw, to secure it firmly. Then the cable of the camera is plugged into a nearby socket for it to be powered.
  • Next, you have to secure your DRV, which is the location where your CCTV recordings would be stored. It is important to keep this in a secure place to prevent it from being seen by intruders.
  • After this, the wiring connections to connect the camera to the DRV are carried out. This should be done with wire moulding to keep the wires safe.
  • The next thing is to connect the BNC port. This is to ensure that the DRV output port is connected to the screen on which you want the video recording.
  • Finally, power on the camera and DRV to test its functionality. Each camera should also be checked to ensure that it is recording well and at the desired angle.

Security is a core aspect of life and a sense of security results in peace of mind for an individual. Therefore, it is important to put in place the necessary security system to safeguard your family and properties.
