How To Know If Your Home Wiring Needs Repair

Your home wiring can be considered as the power highway through which electrical impulses are fed to various electrical appliances in your home. However, home wiring is not a one-time thing. You must keep checking for faults and defects to make sure that there are no potential hazards that might damage your appliances or cause short-circuit.

If you think that electrical wiring deteriorates with age, you might be off the mark. Old wiring is not the only reason why it becomes possibly unsafe. If you have old electrical wiring at your home that does not automatically mean they have to be replaced. Unless there is a performance of safety issue, you can continue with the existing system. Which brings us to the question – How to know if a house needs new wiring?

The best way is to call in an electrical expert. They will be able to do a physical and technical assessment of your home and give you an opinion. However, you too can do some basic checks to determine when to go for rewiring of your home. Look for these tell-tale signs of bad wiring and call a professional electrician proactively before any disaster strikes.

Before you start, consider a few things.

Never tinker with the wiring in your home. Hire the services of a licensed electrical professional to do the work. A trained eye has the ability to locate faults that you might not be able to detect.

Frequent Tripping of Circuit Breakers

Sleek, advanced circuit breakers can be seen in almost all modern homes. These stylish switches have replaced the archaic fuse box. When there is a problem with the electrical circuit, the circuit breaker will trip to turn off current supply automatically. The supply can be restored by flicking the switch back. If your circuit breaker is tripping frequently, it could probably indicate a problem with the wiring. Do not ignore this sign as this may lead to a bigger mishap if left unresolved.

Flickering Lights

Does your household light flicker or dim frequently. This is a problem faced by many homes that use heavy appliances that draw a considerable amount of power. If your wiring is not up to the desired standards, you might experience flickering and dimming. A qualified electrician should be called in to run a check before the problem escalates. The electrician will be able to decide if your home needs rewiring.

Abnormal Functioning of Appliances

All modern electrical appliances including light fixtures are designed to work smoothly. If any of your appliances behave abnormally, it could be because of two reasons – either there is a defect in the appliance or the wiring is bad. A vibration, buzz or a slight shock on turning on an appliance is a clear sign of a serious electrical problem. Your electrician is the right person to find out is there is a problem with your appliance or if the wiring needs an overhaul.

Marks Around Outlets

Do you have any electrical outlets that overheat or have marks around them? Do any of them make a buzzing sound? A sound electrical wiring system will never give rise to such conditions. Heated outlet is a signal that the wiring around that outlet is suspect. Dead outlet is also a sign of bad or defective wiring. It might seem to be a minor issue but the problem could easily flare up.

Damages or Cuts in Wires and Cables

With time, even the best of electrical wires and cables can develop faults. Splices in cables, damaged and frayed wires and exposed insulations can create risky conditions within your electrical system and put lives in great danger. Many times, such problems go unnoticed because the wires are cables are generally concealed. It is prudent to get your electrical system including wiring and cables checked by a qualified professional and the fault, if any, rectified.

Aluminum Wiring

Do you have aluminum wiring in your home electrical system? Your home could be at a greater risk of electrical mishaps than that of your neighbors having copper electrical wiring. Aluminum wiring is susceptible to even seasonal temperature changes which can lead to loose connections and potential short circuits. The concept of Aluminum wire can also be a fire hazard. If your home wiring is still made of aluminum, change to more stable and efficient copper wiring. It could cost you money but it will make your home safer.

Create a checklist and find out if your home has any of these issues and upgrade your electrical system accordingly. The main benefit of doing this is that your home will be well protected and the risks associated with a faulty wiring or electrical system will be hugely mitigated. You can feel reassured that your home, family, and expensive appliances are well protected. Updating your electrical system also can also help increase the value of your home.

Why Copper Is So Commonly Used In Making Electrical Wires

Copper is metal with high ductility and also exhibits one of the best heat and electrical conductivity properties among metals. It is used in a number of applications but one of the key uses of copper is in the electrical industry for manufacturing electrical wires. That’s because copper offers a number of features that are needed to make good quality electrical wires.

Copper is an excellent conductor of electricity and is also one of the strongest metals available today. It sets the benchmark for conductivity with its exceptional capacity to carry and transmit electric current. The conductivity capacity of annealed copper is the international standard to which all other electrical conductors are compared.

Copper wires need a lower level of insulation and smaller conduits when compared to aluminum as the latter is manufactured in a larger diameter size and hence needs a larger conduit to be suitably accommodated. Another major advantage of using copper in electrical wires is that copper oxide also conducts electricity thus preventing the connections and terminations from any overheat situations. Other metals may need oxide inhibition through additives. As copper provides better thermal connectivity, it works better than aluminum, especially where connections and terminations are involved.

Copper Resists Stress

Copper is capable of resisting stress which can cause gradual deformation of metal over time. Stress is a problem that occurs frequently with aluminum, especially at points where there is a pressure on the wiring system. This can result in a loose connection and oxidation. Copper is strong enough to deal with stress and related adversities. That’s why engineers insist on copper wires as it comes with the assurance of durability and performance.

Copper Is Ductile

Copper is regarded as ideal for wiring systems as it offers high ductility. Copper does not conform to the general logic that a stronger metal is usually less pliable. Copper is durable and ductile which provide engineers a couple of more reasons for using this metal in electrical wires. Copper wires do not pose any problem at junction boxes and terminations as it can be bent, twisted and pulled hard without the risk of damage or breaking.

Copper Is Easy To Handle and Install

The inherent properties of copper - strength, durability, ductility, and hardness, make it very easy to work with. When you pull it through a conduit without any stretching and can also be twisted or bent as needed at various points in its installation. Copper wire does not suffer nicks as easily as aluminum. In copper wires, you get a product that delivers high reliability and ease of handling and installation.

Copper Has Immense Strength

The exceptional strength of copper helps the metal resist stretching, breaks and nicks which lesser metals and alloys such as aluminum suffer when pulled through cable trays and conduits. Such damages can affect the current carrying capacity of the wire resulting in wastage of energy and enhanced risk of overheating. The superior tensile strength of copper wires helps avoid such undesirable situations.

Copper Does Not Corrode

Copper is a noble metal that can ensure high reliability and longevity for your electrical wiring system. Copper, in its purest form, does not suffer any galvanic corrosion when connected to other metals and alloys. Copper wiring is also known for its ability to resist corrosion caused by moisture, humidity, industrial pollution, and other atmospheric influences. It can offer a truly trouble-free performance for the life of your system.

Copper Is a Cost-Effective Option

When you buy something that guarantees good performance and can last long, your investment can be termed a something of real value. Aluminum might be cheaper than copper when it comes to electrical wire manufacturing but if you look at other vital factors such as installation and operational convenience along with long term performance, then copper is the clear and indisputable winner. Consider these features of copper:

  •        Has better current carrying capacity through narrow conduits
  •        It is easy to install as no special connectors or tools are needed
  •        Offers high resistance to stretching, nicks, breaks, and corrosion
  •        Relatively maintenance free

Copper Complies With All Codes

Copper has been the mainstay of the electrical industry for many years now and that’s why copper wiring is accepted as the industry’s standard wiring material. Another reason for universal acceptance of copper as the best electrical wiring material is that it complies with all the codes, regulations and ordinances for electrical conductors in the US and most countries of the world. The superior and consistent performance that copper wires deliver in various types of diverse installations has made copper the most favored metal for use in electrical wiring.  
Copper wires can be used for light domestic and residential wiring as well as for heavy duty commercial and industrial wiring. It is easily available which makes copper a great choice as you won’t face any issues during future rewiring.
