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.

Do you find energy conservation confusing? You're not alone. According to a recent study, Americans are by-and-large misinformed about what household appliances consume the most electricity. As a result, homeowners who wish to cut down on the energy they use in their home electrical work might find themselves spending time and resources to improve efficiency in areas where they won't see big gains. Read on to learn more about where most of our energy goes and how you can get the biggest payback for your conservation efforts.

The Failings of Cognitive Accessibility

In general, Americans tend to overestimate the amount of power that is devoted to common home devices like computers, television and lighting, while underestimating the amount of energy that is consumed by bigger ticket items like heat, air conditioning and hot water heating. That's because we confuse the amount of time we spend actively using a specific device with how much power it uses.

“Consumers tend to use the frequency with which they think or interact with a given energy source as a proxy for its consumption,” Ohio State University psychology doctoral student Dan Schley, lead author of the study, said to the Washington Post. For example, someone who spends eight hours a day working on a computer might naturally be inclined to think that device is what's driving up the electricity bill.

How to Make Your Actions Count

However, it turns out that the energy consumed by common electronics is dwarfed by what goes into major appliances. According to the U.S. Department of Energy, a whopping 48 percent of energy in the average home goes toward heating and air conditioning. The hot water heater takes the next largest individual chunk, at 17.7 percent. The refrigerator uses 13.7 percent, with all other appliances and electronics accounting for about 21 percent of the total.

The upshot? If you really want to cut back on consumption in your home electrical work, you need to target the biggest guzzlers. That means making interventions like installing smart thermostats, turning down your water heater temperature and beefing up the insulation in your home. The simplest, most effective change that most families can make is to bump the thermostat down a few degrees in the winter and up a few degrees in the summer.

Don't Neglect the Small Stuff

That's not to say you should ignore simple behavioral changes that can save money in other areas of your home electrical work – things like unplugging devices when they aren't in use, installing energy efficient cable boxes, using the power-saving settings on your computer and turning off the lights when you aren't in the room. Just treat these items as the appetizers and desserts of your energy-saving strategy, rather than the main course.

If you need help identifying the largest loads on your home electrical work, arrange for a visit from an expert electrician today.

Electrical jobs should never be turned into a DIY project, unless you have formal training and experience in the field. While electricity is extremely useful and necessary, if it isn’t handled correctly, it can be pretty dangerous too. If you get a novice to handle the job for you that can result in overloaded circuits, poor wiring connections or even faulty grounding, which can be extremely dangerous to you and your family and result in a fire outbreak as well. Here are some common services for which you would need to call in an electrician:

The main electrical panels provide electricity to your entire house. If you have older panels with fuses and older wiring, those may not be able to bear the load of any new appliances you decide to install on your property. The latest electrical appliances tend to add heavy loads on the system and your older wiring installations won’t be able to support those loads. If you are getting new appliances, call in a licensed electrician to test and inspect the wiring and circuit breakers on your property.

If you need any new outlets installed or need existing ones converted to USB ports, you would have to call in an electrician for the job. Oftentimes, electrical codes necessitate that a minimum of 1 outlet in your kitchen and bathroom be a GFCI outlet. These are specifically designed to shut off the power in case there is an imbalance in electricity or if water comes in contact with any of the electrical equipment or fittings; this helps in preventing shock in these areas.

It’s important that there be proper grounding as lack of it can result in power loss or a fire. Aside from this, if you require any additional outlets, your electrician will be able to install those for you as well. Installing additional outlets requires replacing a segment of the wiring and cutting into the walls, and this is something you should never do on your own. Many new electrical gadgets come with USB charging systems and you can get the local electrician to replace some of the standard ones with the USB ports, if required.

There are times when homeowners feel that the outdoor spaces on their property can do with better illumination. If you want new security or ambient lighting installations, you should just call in the electrician. He will extend the wiring to the outdoor spaces and ensure that it has the proper grounding as well. They will provide advice on which electrical fixtures would work best in an outdoor setting.

This may seem like an easy job, but it’s best to get a professional electrician to handle this for you as well. The electrician will check whether the amperage is sufficiently high to support the wattage of the new light fitting. If it is lower than that, the electrician will have to extend an additional wire from the main circuit breaker.

Aside from this, even things like fitting powerpoint covers and replacing light switches is something that only a certified and licensed electrician should handle. They will take all the necessary precautions while doing any kind of electrical work on your property.

Although any light will help alleviate the strain on your eyes while looking at a screen, there is a right and wrong type and location for the light to have the best effect. As mentioned earlier, bias lighting is placed behind your screen to establish a brighter field of view so that your eyes aren’t constantly trying to find a balance between light and dark. Bias lighting illuminates a room without creating glare or reflections on your screen, shining directly in your eyes, or affecting how you see contrast and colors. Other sources of light, such as ceiling lights or lamps, can do all of the above.

If light is shining onto your screen, there’s going to be a noticeable difference in how the picture appears. Colors won’t be as vivid, and the screen might be hazy. In an attempt to remedy the situation, you could adjust the brightness and contrast. However, these adjustments will decrease the life span of the bulb or LEDs in your screen. The adjustments will also result in increased energy consumption along with a higher electric bill.

Adding light behind your screen instead of in front of it will eliminate any color or contrast issues. Dark scenes or colors will look richer against a white illuminated background. The picture below demonstrates how dark colors are lost against a dark background.

howtogeek.com, “. . .  you want a bulb temperature that is as close as possible (if not identical) to the reference point used in the industry that both manufactures the screens you’re looking at as well as creates content for said screens and that’s 6500K.” He goes on to say that, “The bulbs (be they CFL or LED) inside your HDTV or monitor are calibrated to 6500K, the film and digital video shot is color corrected to have a 6500K white reference point, and the editing suites where content is edited and worked on have 6500K bias light.”

So what exactly does 6500K mean? Correlated color temperature (CRI). CRI refers to how accurately a light source reveals the true colors of objects, people, and surroundings and involves a distinct testing method with comparisons to incandescent light or daylight. A light source with a CRI close to 100 shows colors very similarly to how daylight or incandescent light shows those same colors. To get the best picture, you’ll want bias lighting with a CRI as close as possible to 100.

We carry LED strip lights that are great TV backlighting options and will help you achieve the best picture on your screen.

Our variable color temperature controller and remote. The strip also has a CRI of 91, which will show screen colors accurately. This strip can be purchased in 3.28- or 16.4-foot lengths that can be cut and connected where needed with strip light connectors.

Another great option is our 6500K LED strip with LC2 connector. It has a CRI of 79 and is available in 1.64-, 3.28-, and 16.4-foot lengths. The peel-and-stick strip can be cut and connected where needed with compatible strip light connectors.

A kit in cool white is also available and is a convenient bias lighting solution. It has a 6500K color temperature, 79 CRI, and includes everything needed for installation—power supply, dimmer, remote, connectors, etc.

The strip lights listed above have peel-and-stick adhesive backings and can be cut or ordered in lengths to fit every screen size; strips are marked with designated cut lines. If you don’t order a kit, you will need a power supply and can purchase a controller with remote for dimming.

An easy installation method is to use a continuous length of strip around the back of your screen. For a cleaner look, you can cut the strips at all four corners of your screen. If you plan on cutting your LED strip lights, you will need 4 connectors (already included with the kit). All compatible installation supplies will be listed under the accessories tab on each product page. The following instructions explain how to install LED strip lights by cutting them into sections. Note that installation methods will differ depending on the strip you choose.

1. Cut your LED strip lights into lengths that fit the back of your screen. Because we offer different lengths, you might be able to order separate strips that will fit all four sides of your screen.
