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.

Maintenance Factor

Illumination Systems are designed to fulfill the required lighting level at the end of an operation term and not at day one of the new installation. The luminous flux of the system is going down over lifetime. This is a normal process, no product is lasting forever but the required illuminance levels should not be depreciated at any time. If a lighting system is setup, the maintenance plan has to be fixed too. So the facility managers know how often to clean the room, the luminaries and how frequently to change lamps. A reasonable time needs to be found between maintenance and operating hours, as maintenance cycles are connected to costs. The longer the operation time without maintenance, the more luminaries need to be installed to guarantee the required illumination level at the end of the term. The more frequent the maintenance cycles, the higher the maintenance factor, but also the related costs for the facility service.

Which Points are influencing the Maintenance Factor? Different factors influence the decrease in lighting level like the soiling of the room surfaces, the soiling of the luminaries, depreciation of luminous flux by the light sources or lamps failure.

Room Surface Maintenance Factor: The room surface maintenance factor is the ratio of the room surfaces reflectance before and after cleaning. It is the reduction of the lighting level according to soiling of the room. Luminaire Maintenance Factor: The luminarie maintenance factor is the ration of the luminaries luminous flux before and after cleaning. It depends on the luminarie construction and design (open housing or closed one) as well as on environmental conditions (dirty or clean). Lamp Lumen Maintenance Factor: The lamp lumen maintenance factor is the ration of luminous flux at a specific time compared to a new lamp. It is describing the aging of the lamp or the reduction of light intensity over time. Manufacturers offer comprehensive tables about their lamps luminous flux behavior. Lamp Survival Factor: The lamp survival factor depends on the service lifetime of a lamp. Some lamp lifetimes are reduced by frequent switching. The lamp manufacturers provide tables indicating the lamp survival factor. If a lamp is not working any more, the decision for immediate replacement or group replacement needs to be taken. If the lamp is replaced immediately (mostly in areas where the luminaire is easily reachable) the LSF can be set 1. On the other hand, the decision could be to replace lamps in special terms or group-wise. This could be the case in huge halls, where machines need to be stopped to reach the luminaires.

A maintenance factor of 0.8 shows, that the new lighting system needs to be over driven by 25% not to undercut the minimum required illumination level after 10 years. LED lighting systems are flexible and easy to connect to control systems. The installed load will provide efficient luminous flux at the end of the operation time but the energy that is “over” in the beginning can be saved. The new installation would illuminate an area with required 300lx by about 450lx. The energy can be saved by lighting management systems that are regulating the power concerning the luminous flux depreciation. HID lamps are not easy to control. The energy load that is “over” in the beginning is wasted. No change to save it.

Conclusion: Think carefully when setting up a lighting installations maintenance plan. This starts already with the choice for the light source. LED Modules are efficient, likely not failing and offer long lifetimes between 50,000h and 100,000h. The control possibilities are comprehensive. The luminaries overload, that needs to be installed to guarantee the end of lifetime illuminance levels, can be saved by light management systems. Regarding all the mentioned points, LED is the competing light source. The features are dominant over traditional light sources. Take the chance and install or renew your lighting system by  energy efficient LED light sources and luminaries.

We’ve begun installing chargers for electric cars in Los Angeles – thus my new interest in electric cars. Interest in electric cars (electric vehicles or EVs) is picking up because the Nissan Leaf just began deliveries in L.A. in December and the Chevy Volt is supposed to start deliveries early this year. Los Angeles buyers are starting to install electric chargers for these vehicles, and I’m starting to learn a lot more about EVs.

Of course, as someone who installs chargers for electric cars, I’m interested in how many will be sold in Los Angeles. Sorry folks, no one really knows. Forecasts are all over the board. Pike Research, a transportation analysis firm, just projected in early 2011 that in the next six years, between 2011 and 2017, over 96,000 electric vehicles will be sold in Los Angeles. It projects that Los Angeles purchases will be second highest in the country, trailing only New York City. Its overall projection is 366,000 EVs  sold nationwide by 2017.

Another study in 2009 by the University of California, Berkeley (Center for Entrepreneurship and Technology) projected that the U.S. will hit 1,000,000 EVs sold by 2017. This is still far lower than President Obama’s call for 1,000,000 by 2015, which many analysts consider realistic.

Why are the projections so different? The U.C. study explains. It mostly depends on the price of gasoline. For example, if gas prices continue at about $3.50 a gallon, U.C. forecasts only 18% of new car sales will be electric in 2020. But if gas prices rise to about $5.50 a gallon, the forecast rises to 45% of new car sales in 2020. Of course, experience tells us that gas prices move up and down very quickly and unexpectedly, often depending on events in the volatile Middle East.

The safest statement one can make about electric cars sales in Los Angeles is that they’re starting in a big way now and will continue to increase over the coming years. Another safe statement – buying an electric car and installing a charger is going to protect you from the wild ups and downs of gas prices, something no one can predict.
