One of the most popular tools in any home is the extension cord.  For a long time, rooms would be built with only one or two outlets, creating the need for additional power strips and extension cords as we moved into a more digital world.  As more devices found their way into our homes, the NEC updated standards for home construction to require additional outlets and electrical accessibility in each room.  Unfortunately, most homes still lack the proper number of outlets, and when a cable can’t reach, most of us will reach for an extension cord.

Most of the time, this isn’t a problem.  Extension cords function exactly as their designed to.  When you need a longer cord to place a fan or give a little extra reach to your vacuum cleaner, there’s nothing dangerous going on.  Where extension cords become risky is in their overuse.  Many people buy the longest, cheapest cord they can find and this is where danger sets in.

Electricity and metal have a very interesting relationship.  As current, the flow of electricity over a conductor, increases in a wire, the temperature increases.  Current is also adjusted as resistance increases to keep power at the same level.  When you add wiring to a circuit, the resistance of the wire itself stacks with the rest of the components on that circuit.  While one electrical cord doesn’t add much in the way of resistance, multiple cords will continue to increase the amount of power being used in the system.  As the current increases to keep up with the new demand, the temperature in the wiring also increases.

This relationship is used to great effect in your circuit breaker, where the difference in heat forces a breaker trip that protects your system.  In an extension cord that isn’t designed to handle the load being placed on it, insulation melts and fires can start.

Keep in mind that extension cords are always temporary.  Never use an extension cord for anything permanent.  They are designed to help you reach electricity for a task and nothing more.  When in doubt (or if you hear buzzing coming from the wiring, socket, or circuit breaker) switch to a higher amperage circuit and a lower gage wire for your extension cord (the lower the gage, the thicker the wire and the more current it will be able to handle).

According to the Electrical Safety Foundation International, Guidelines for using an extension cord are as follows:

Remember that the more power you need, the more current you’ll be using.  Any device that includes a motor or heating element will either need an industrial-grade extension cord (power tools) or should not be used with an extension cord at all.

One of the greenest home improvement projects that you can undertake is to install solar panels. As more research is conducted, it is becoming more and more clear that our reliance on fossil fuels is one of the main contributors to not only our planets overall health, but the health of everyone who lives here. As a homeowner, working with solar panel installers to reduce your dependence on less renewable sources of energy can not only give you more energy freedom, but also help the environment at the same time. Plus, you could save a significant amount of money in the process.

Cost of Solar Panels

As a result of technological advancements, increased demand and the variety of payment options for solar panels, the cost is more affordable than ever. Although purchasing panels and the systems that go with them up front can be very expensive and cost prohibitive, many solar installers are offering alternative to this process. One of the most popular options is the solar lease. Rather than buying panels up front or financing their purchase, you can actually lease solar panels from a solar leasing company. This gives you both the solar power that you desire and the financial flexibility that you need.

Solar Leasing

Solar leasing is by far one of the largest growing trends in the solar power industry. The way it works is simple. You work together with a solar installer who will install the panels on your home for you. You then pay them a monthly leasing fee for the use of the panel. All of the electricity that you generate belongs to you and any excess can be sold back to the power company. As a result, you will typically start saving money in your first month.

At Solar Panel Info, we have compiled extensive information on the benefits of solar panel and solar leasing.

In an effort to recognize the ever-increasing impact television has on people living all over the world, the United Nations General Assembly created World Television Day on November 21 back in 1996.

Ever since the very first televised images were produced in the 1800s, TV has obviously advanced by leaps and bounds, especially in recent years. Mr. Electric invites you to take a moment to appreciate the many services and capabilities having a television provides, particularly in a time of multi-screening, and all the advanced features available from today’s hottest technological offerings.

Education: Public broadcasting and other educational channels serve to educate the young and old alike. Television is an excellent resource for learning how the world works and getting people interested in math, science and other important fields.

Information: Whether you’re hoping to learn more about political candidates, receive updates on wars, learn what’s happening in your local community, or stay on top of breaking news around the world, TV is an excellent source of information. It’s faster than printed news because the latest stories can be broadcasted immediately.

Entertainment: There’s nothing like winding down after a long day in front of the television. Endless categories of entertainment are available, from comedies and dramas to horror and thrillers. Don’t forget the way TV has changed the way we watch sports. Football wouldn’t be what it is today with television.

Relationships: People can bond with one another based on what’s on TV. Whether it’s watching a favorite show together, tuning in to a political debate to spark conversation or watching your team make it to the Super Bowl, TV brings people together.

Inspiration: Just as people can be inspired by what they see walking down the street, television can also spark inspiration. This leads to new fashion designs, inventions and technological advancements.

Cultural influences: TV is a huge contributor to pop culture. Trendy shows become the talk of the town. People become excited about what happens to the characters in a particular TV show and an entire generation is impacted by it.

TVs are becoming more advanced and high-tech than ever before. These advancements help you get more out of your television.

“Smart” functionality: A smart TV has Internet features, making it an example of today’s popular convergence of computers and televisions. This functionality opens up an entirely new way to watch TV, allowing for on-demand video streaming, home networking access and social media interaction, in addition to the basic broadcasting media available on standard TVs.

Multi-screening: An increasing number of people have Smartphones today. This encourages multi-screening, when television viewers weigh in on what’s happening live on social media, particularly Twitter. This connects people who have never met and lets them discuss and debate topics they’re both interested in.

4K resolution: Also known as ultra high definition, 4K resolution is a relatively new technology that has yet to become the standard because compatible content is still quite limited. 4K televisions are equivalent to 2160p, as compared to 1080p for standard high definition. As this technology becomes more ubiquitous, the television-watching experience will become closer to real life than ever before.

Curved TVs: This new innovation attempts to mimic the way you perceive the real world. The result is a more immersive, realistic experience that gives the illusion of watching content in a wider field of view.

Celebrate World Television Day in style with a new media room in your home. If you’re interested in adding one, please contact Mr. Electric® for a professional installation. We’re here to power your home's tomorrow.
