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.

It’s tuesday April 22nd and Earth Day* celebrations are abounding. Eco-friendly lamps, light fixtures and fabulous accessories are here to help you decorate with an eye on preservation and divine design.

The “Smart Home” of the future is truly within reach.  From aroma-therapy air purification systems and vitamin-C infused showers to LED light sources and recycled decorative illumination, energy-saving and eco-friendly options are in full bloom this year.

1.  Look for ENERGY STAR and Energy SMART products.  Revamp your indoor and outdoor light fixtures with new light sources and smarter control systems.

2.  Invest in sustainable lamps and light fixtures.

3.  Buy less, but buy better.  From Organic Minimalism to Restoration Industrialism, the latest designer lamps and light fixtures may be less ornate, but full on fashion with energy-efficient illumination.

Visit 1800lighting.com or a Capitol Lighting showroom for a glimpse into the latest eco-friendly lighting and decorative accessories, including  new lamps and light fixtures from Hubbardton Forge, Varaluz Lighting, Kichler Lighting and Currey and Company.

Now is the time to do your part to make Earth Day 2014 more than just a fantastic idea, make it a reality and light consciously and proficiently with style.

*The EPA (Environmental Protection Agency) was born on December 2, 1970 and the first Earth Day was celebrated on April 22, 1970.  President Nixon’s 1970 State of the Union Address was flooded with concern for clean air, clean water and a concerted effort for the federal government to “transform” the land.

We celebrate Earth Day every year on April 22nd as the government continues to consolidate efforts for a cleaner environment, but it is really up to each individual to transform their own home with energy-efficient and eco-friendly products.
