Sydney is the oldest and largest city in Australia, and also called the Harbour City. It gets more than 300 days of sunshine every year, and about 100 days of clear skies. This large city in Oceania is home to 5 million people. It also has the reputation to be an ethnically and culturally diverse city due to its long-term immigration. Suburbs surround the city centre of Sydney, forming a vast metropolitan area. In it are many old and beautiful houses, sprawling together.
If you are one of those people residing in an old house in Sydney, it is essential to have a professional check the wiring for deterioration or damage. Know that age is not the only factor that would indicate the wiring is unsafe, or in need of replacement. An experienced electrician Sydney can assess the condition of your wiring properly and determine its electrical load. Here are some other things you can inspect to give you any indication of the status of your electrical system.
Can You Continue Using Old Wiring?
Even though they are considered outdated, you can still use knob and tube wiring in your home. If you want, you may add extensions to any existing knob and tubes, but make sure you use proper techniques and materials. Usually, old houses have special legal permission to restore their knob and tube systems.
In case the knob and tube wiring in your home needs some work, you may connect a new non-metallic cable to the old wiring. Use junction boxes to give protection to the electrical connections. Keep in mind that the work you do on your wiring, including the knob and tube system, must abide by the local code regulations.
Common Electrical Issues to Look for
Old wiring can become a high risk when the insulation has suffered from tear and wear. If the alteration or installation is incorrect, the wiring may overheat and cause a fire. The following are common problems to watch out with old wiring and signs that you need to replace them:
- Fuses with more than 15amps. Somehow, the older wiring does not fit the large appliances today. Modern appliances usually need 30, 40, or 50amps. Therefore, a knob and tube system that uses 30amp will likely cause an over-fused circuit. For safety purposes, fuse the circuits of your old wiring not higher than 15amps.
- Wire insulation that is missing, cracked, or damaged, which exposes the metal part of the electrical wiring. It is a common problem with old wiring systems. It is better to leave this concern to a professional electrician of Sydney.
- Building insulation surrounds the wiring. When insulating, particularly the attic, double-check if you are surrounding all the knob and tube wiring that has loose batt and fill insulation.
- There are some exposed splices that are covered with plastic electrical tape. Those exposed splices outside an electrical box often indicate that the wiring is not soldered. Make sure they are soldered.
The information above helps you to be proactive and responsible in handling the status of your electrical system. With old houses, there is a high possibility that problems with the wiring are lurking. If you are not familiar with electricity, it would be best to consult with a trained and licensed electrician.
