If improperly installed, aluminum wiring can raise the risk of a house fires! From 1960’s up to the mid 1970’s aluminum wiring was sometimes used for branch circuit wiring instead of copper wiring.  During this time period copper prices were very high and aluminum wiring became a cost effect alternative to copper wiring.  Was aluminum wiring found to be as good as copper wiring?  Not even close!  Aluminum wiring quickly became a fire risk if not installed properly.  At the time aluminum wiring methods were exactly the same for copper.  Over time it was found that improper installation methods and electrical devices not designed to accept aluminum conductors could lead to fires.

If was quickly found out that aluminum wiring could cause flickering lights, hot electrical connections and even burned or melted insulation on the wiring.  There was a severe problem with overheating which can lead to fires.

1.  A Softer Metal.  Aluminum is a much softer metal when compared to copper.  During the stripping process from aluminum it can be easy to nick.  These nicks can cause hot spots in the conductor causing overheating and the potential risk of fire.  Electricians had to develop different methods of stripping the insulation off of the aluminum wiring to avoid damaging the conductor.

2.  Aluminum Expands.  When an appliance demands electricity on the circuit the conductor heats up.  While this process takes place with copper conductors too aluminum expands at a much greater rate than copper.  This expansion and contraction of the aluminum wiring  caused the the conductor to creep out from under the terminal screws on breakers and electrical devices such as plugs and switches.  This creeping of the wiring resulted in a loose connection which lead to sparking and potential fire.

3.  Corrosion or Rust.   When steel rust it becomes red, on copper rust is green, and on aluminum it is white.  When copper wiring rust it’s not as big as problem when compared to aluminum, copper rust is actually electrically conductive.  This rust on copper still allows the electricity to flow and doesn’t create as much resistance of the electricity or simplify put it doesn’t interfere as much.  However, when aluminum rust it forms a white oxide which is not a good conductor of electricity.  This creates resistance or reduces the flow of electricity.  This resistance interferes with he flow of electricity, and can cause overheating leading to fires.

There are several options for you if you have aluminum wiring in your home.  We can evaluate your homes wiring and come up with several effective methods and affordable price ranges.  It’s important to have your homes wiring thoroughly evaluated so you can know the truth about its condition so you can make the proper decision.

Solution 1.  Rewire the entire house with copper wiring.  This would be the safest long term solution for aluminum wiring.  This method would require reduced maintenance and reduced inspections needed when compared to aluminum wiring.  Rewiring the home is the safest long term solution to aluminum wiring when compared to other methods.  This solution can be expensive when compared to other solutions.  However, we have a variety of financing options and payment plans available for almost every budget.

Solution 2.  Check all connections in home and repair as needed.  Then re device the entire home with aluminum rated devices.  This short this method entails replacing all the homes plugs and switches with ones that are designed to accept aluminum conductors.  It’s important to note aluminum rated devices can be hard to find at the big box stores.  When these devices were first introduced they simply had a larger screw or terminal for the aluminum conductor to fit under.  Unfortunately, these CU/AL devices failed to work good enough and was not an effective solution.  New devices CO/ALR are created out of a similar metal which shares a similar expansion and contraction rate as aluminum which reduces the creeping of the conductor.

Solution 3.  Pigtailing.  Pigtailing simply means taking the aluminum wire connections that go to the device and splice on or pigtail on a copper conductor to go to the device such as a plug or a switch.  It is important to note that it does take a specially designed wire nut or twist-on wire connectors to to perform this method.  While this method is the cheapest it is important to make sure that routine safety checks and inspections are performed on your homes wiring to reduce the chances of future problems.

Even with all the disadvantages, aluminum wiring still has its advantages under certain applications.  It’s important to note even with these advantages you should not use aluminum wiring in your home for standard 15 or 20 amp branch circuits.

1.  It’s Light Weight.  Aluminum is lightweight in nature.  Being lightweight is an advantage when conductors are used over long distances.  This lightweight property is most beneficial for aerial applications were the aluminum wiring is suspended between poles.  This wiring method is most commonly seen in utility company applications and telecommunication lines.  Being light weight also makes the aluminum wiring easier for the installer to work with.  This makes the cable less physically demanding to install.

2.  Aluminum Wiring is Cheaper.  Aluminum wiring can be half the cost of copper wiring.  When a large amount of wiring is needed saving half the cost can be a huge benefit over copper wiring.  This method is mainly seen in feeder circuit applications in commercial buildings as well as sub panels and 220 circuits in residential applications.  It’s important to note this practice of using aluminum wiring for sub panels, services, and 220 circuits in residential applications has been deemed acceptable when properly installed and connected.

As part of our series on pop culture from 15 years ago – a continuing celebration of our 15th anniversary as Pegasus Lighting – here are 15 moments from March 1999 you may remember. Monica Lewinsky’s book on her affair with Bill Clinton goes on sale; the Dow Jones average beats 1000 for the first time; and The Matrix is released. Ah, the sweet 90s. Where were you?

1. Jar Jar Annoys Basically Everyone

At the Golden Raspberry Awards, better known as the Razzies, the award for Worst Supporting Actor went to Ahmed Best, who voiced the character Jar Jar Binks in STAR WARS: EPISODE 1, THE PHANTOM MENACE. Poor Jar Jar, you-sa not much appreciated by STAR WARS fans.

2. The Worst Picture of the Year

The Roth 401(k) combined elements of the Roth IRA and the traditional 401(k). In a traditional 401(k), you contribute income without paying taxes on it. You then pay taxes on the funds when you withdraw them during retirement. With the Roth 401(k), however, you pay the taxes upfront so that you can withdrawal funds tax-free during retirement.

 5. The Melissa Worm Attacks the Internet

At the end of March 1999, the Dow Jones Industrial Average closed above the 10,000 mark at 10,006.78. This was unprecedented! People made “DOW 10,000” hats and celebrated. In hindsight, people wonder whether that day represented the peak of our economy’s health up to that point or the peak of market excess that was responsible for the economic instability of the 2000s.

7. You Are the One, Neo

Legendary film director Steven Spielberg was once again named Best Director at the Academy Awards for SAVING PRIVATE RYAN. In fact, the director of early 80s movies like E.T. was on a real tear, just coming off of the JURASSIC PARK series and SCHINDLER’S LIST. He continues to direct great movies today.

9. Roberto Begnigni Is Exuberant 

Roberto Benigni won Best Actor for his role in LIFE IS BEAUTIFUL at the 1999 Academy Awards. His reaction immediately became more popular that the movie itself. I’ll have a glass of whatever he’s drinking!

10. Gwyneth Wins Best Actress

SHAKESPEARE IN LOVE was the most awarded film of the night of the Academy Awards. Perhaps the most touching award acceptance, though, was Gwyneth Paltrow’s. Try to watch her acceptance speech without getting teary. I dare you.

11. Lewinsky Tells All

In March, 1999, The Supreme Court of the United States upheld the murder convictions of Timothy McVeigh for the Oklahoma City bombing, which left too many dead and wounded to even go into detail here. It was a tragic and totally unnecessary crime, and the Supreme Court decision echoed the feelings of many Americans.

14. Stanley Leaves Us

On the day after we lost Stanley Kubrick, we lost another beloved American hero, the legendary baseball player Joe DiMaggio. His death was caused by lung cancer. He was 84 and sure saw America from an interesting point of view. The loss of this former star was felt all over the nation.

It’s fun to think back to these moments in the popular culture of 1999, even though not everything that happened was happy. Most of us lived through all these events and remember them well. Come back next month to see what we resurrect next.

It is estimated that thousands of electric shock accidents take place each year, of which some are fatal ones. Aside from this, there are incidents of electrical fires caused by poorly-installed or ill-maintained wiring. It’s important to understand that most of these fires and accidents are avoidable. There are some simple things you can do to prevent an electrical fire from erupting on your property, including:

Never try to force plugs into the outlets and don’t remove the third prong which is the grounding pin, to fit it a plug into an outlet with 2 prongs. Do not plug in too many appliances into a multi-plug outlet.

Check whether there are any loose-fitting plugs as these can be a fire/shock hazard. If you notice that any of the wall plates are broken/missing, replace them without delay. So that the components and wiring aren’t exposed. If you have very young kids in your home, make sure that you cover all used outlets.

Check the cords for fraying or cracks. Pay special attention to ones that are placed in any high traffic areas or under rugs and carpets.

Make sure that the wattage of the bulbs is compatible with the fixture requirements. If you find any bulbs with a higher-than-recommended wattage rating, replace them immediately. It’s also important to ensure they don’t overheat and that they are screwed-in securely.

These should never be used on a permanent basis. Use ones that have safety enclosures to protect kids from burn injuries and shock.

There should be GFCIs installed in the kitchen, bathrooms, garage, basement and various other indoor and outdoor outlets in your home. Test these on a monthly basis to ensure they are working as required.

Only older properties have fuse boxes and these don’t have the capacity to withstand the heavy electrical loads required by modern-day equipment and appliances. It’s far better to get these older systems evaluated by a skilled electrician and replace them with modern circuit breakers.

Faulty or old wiring is one of the commonest causes of residential electrical fires in Australia. Get these checked periodically for loose connections, loose wall fixtures or wall receptacles. If you hear any hissing, sizzling or popping sounds behind walls or from sockets, call in your local electrician without delay to get these installations inspected and replaced. If you find that any switches or electrical fixtures are hot to the touch, get those checked as well. Flickering light bulbs are another indication of problems in the electrical wiring as well and it’s best to get a thorough check conducted.

If you find that a specific circuit breaker trips repeatedly, or you experience shock when you touch it, you should unplug it immediately and get it replaced or repaired. Check for damage or cracks in the connectors and wiring and install surge protectors to protect all your expensive electronics.

When you upgrade your home, make additions or add extensions like extra rooms or an extra storey etc., or even add a large number of new equipment or electrical appliances to your home, that can overburden the existing electrical installations. At this point you would have to increase the service capacity of your home’s electrical system.
