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.

We’re excited to announce that we now offer Printed LED Panel Lights for custom backlit signs, trade show and exhibition displays, product advertisements and branding, mobile displays, logos, and so much more! Our user-friendly panel building tool lets you configure a panel in four easy steps. Simply choose your ideal panel size, upload or select an image, edit your image, and choose a frame. You’ll be able to see your panel as a finished product with all chosen options. Compatible accessories will be listed before you reach the checkout page.

There are many aspects of our Printed LED Panel Lights that make them unique. Check out the information below to see why they’re so special.

We offer three types of panels: wall-mount, stand-alone, and 12-volt. These LED panel lights are available in a variety of sizes and are designed specifically for their intended applications.

Stand-alone panels come with a plug and a wire enclosure box. They can be used almost anywhere for any purpose from backlit signs for product showcasing and branding to window signage and custom logo displays on desks and shelves. These panels are available in 2′ x 2′, 2′ x 4′, and 1′ x 4′ sizes.

It is a cold October evening and you are preparing dinner. You are in full motion with all your appliances working overtime to get the meal done as soon as possible – and the power shuts off. Not only are you frustrated because you are set behind schedule but now you have to try to fix the problem. This happens to people on a daily basis and is a nuisance that can be avoided with the right electrical usage and correct setup. Lets walk where you should go from here.

As we have discussed in the past, the electrical panel (or breaker) is an integral part of the home’s electrical system. It regulates all incoming electricity and manages it throughout your house. When a breaker shuts a circuit off, or it “trips”, it is protecting you and your home from a potentially dangerous situation. The breaker will shut off that circuit because it has detected high voltage, high temperature, or another internal problem. If the breaker does not trip the circuit that is affected can overload and create an electrical shock or electrical fire.

To get your electrical breaker back on, identify the circuit that is in the off position and flip in back to the on position. With a properly labeled electrical panel it can be easy to quickly identify the affected circuit. If the breaker feels hot the touch or the circuit immediately trips again, do not attempt to turn it back on and call an expert electrician. Sometimes a circuit could trip due to a high amount of usage and may only be a minor problem with no repercussions. But if the breaker immediately trips when turned backed on or it trips regularly, there is a larger cause and the problem should be addressed as soon as possible.

There are a number of reasons why breakers could trip. The circuit that is being turned off could potentially have too much load and being overloaded. There could also be a problem in the wiring itself that is causing electrical surges and shorts that the breaker is detecting. It could also be a problem with the breaker itself. The panel may be old and reaching the end of its functionality. It may be time for the panel to be replaced.

It is not a good idea to keep turning on your breaker if it continuously trips. If you cannot identify a pattern in your routine that is causing the trip you should contact an Expert Electrician. They will be able to tell you if the problem is originating from the wiring or within the panel and even fix the problem for good.

Don’t put up with tripping breakers, it will become more than just an inconvenience. Get the right help and have peace of mind that your home is safe and dinner will get finished on time.
