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.

With the start of the school year and the holiday season approaching, it seems as though the mound of expenses just keep piling up. You’re budgeting for school shopping, lunches, holiday shopping and making sure your lights stay turned on. This season tends to be the most expensive for many home owners.

Luckily, we have a few ideas on how to cut back on utility bills and lower your electric bill. We also provide home inspections for everyone in the Northern Virginia area and look at ways you can utilize the most out of your electrical appliances. You may be heading into a time filled with many expenses but you can pad your pocket with money saved from lowering your utility bill. Check out these tips that will help you with your utility bills and give you peace of mind during this hectic season!

Install Dimmer Switches

When you install dimmer switches, you can use only as much light as you need. With a traditional light switch, the only settings are on and off, meaning you are either using 0% electricity or 100%. With a dimmer, you have an entire spectrum of settings in between. Being able to decrease the amount of light you use inevitably results in lower energy bills. Install dimmers in the rooms you use the most like the kitchen, living room, bathrooms, and bedrooms; this will allow you to take advantage of the greatest savings possible.

Keep Your Fridge and Freezer Full

Everyone always tells you to keep the fridge closed. But did you know that keeping your fridge and freezer full can also save money? Food acts as insulation and lessens the amount of time that the fridge has to run to stay cool. This will be easy to do with all of those lunches your family will have to pack for school and for the Thanksgiving and Christmas holidays.

Install Ceiling Fans

Keep the air circulating in your home, and your air conditioner won’t have to work as hard. Ceiling fans can help lower your electric bill by up to 30 to 40 percent. While a ceiling fan doesn’t actually decrease the temperature of a room, the draft makes the room feel cooler – allowing you to raise the thermostat and be just as comfortable. You can even use your ceiling fans in the winter months! Many people are unaware that ceiling fans can be used to circulate warm air during cooler months of the year. By running the blades clockwise, ceiling fans push warm air down from the ceiling without creating a draft.

Get Rid of “Phantom Loads”

A shocking 75 percent of the energy used by home electronics is consumed when they’re turned off. These “phantom” users include: televisions, videogame consoles, stereos, computers and many kitchen appliances—basically anything that holds a time or other settings. A simple solution? Plug all of these items into power strips; then, get in the habit of turning off the strips between uses.  This will cut back on utility bills and will help combat overloading fuses.

Switch to LEDs

LED light bulbs use 90 percent less energy than incandescent bulbs. Switch out the most widely used bulbs in your home. Then, replace the rest as they burn out. LED lights tend to last much longer than traditional bulbs so you won’t have to replace them as often – saving you money.
