Unfortunately, the places where you need to use electricity and the places where your outlets are installed may not synergize as well as you would hope. Most homeowners solve this issue with the use of extension cords, but this can do more harm than good if you aren't familiar with extension cord safety. Here are four tips you should know before you use extension cords in or around your home.
1. Don't Cover Extension Cords During Use
Overheating is one of the most important things to consider to prevent electrical fires. Extension cords can overheat much faster depending on the environment they are used in. You should always ensure there is plenty of space around an extension cord for the entire length of the cord. In addition to a greater risk of overheating, damage to a covered extension cord can easily go unnoticed for much longer.
If you use an extension cord indoors, you should never run an extension cord through walls or ceilings to deliver power to another room. Similarly, avoid laying extension cords under carpets, rugs, or furniture. When you use an extension cord in these ways, it's not only risky because it traps heat, but people in your household are more likely to walk on covered extension cords. This can break down the wires inside over time.
2. Don't Use Indoor Extension Cords Outside
Outdoor extension cords are insulated with much more resilient materials than those designed to be used indoors. This is necessary to protect the cord from moisture, oil and chemical spills, and other destructive outdoor elements. Most outdoor extension cords are also made with a wire that has a larger gauge since they often need to transfer current over a longer distance.
These key differences illustrate why it is okay to use an outdoor extension cord inside, but that an indoor extension cord should never be used outside. Examine the packaging carefully on any extension cord you buy to find the manufacturer's recommendation for proper use of the cable.
3. Never Chain Extension Cords Together
Chaining extension cords together introduces a host of new problems and should always be avoided. A significant risk of chaining extension cords is that the resistance of the series of cords increases as the length increases, which in turn generates more heat and creates a fire hazard. The total power available to the connected appliance is reduced, and your breaker might not trip if a fault occurs in one of the cords.
When you use extension cords in series it creates several weak points in the connection since the plugs can easily pull apart. Performing any work that requires movement is virtually impossible since it could pull the cords apart at any moment. Worse yet, the extension cords could spark when they have pulled apart and can cause a fire if anything flammable is nearby.
4. Inspect Extension Cords Regularly
Even if you follow every tip to safely use extension cords, there's no substitute for regularly inspecting your extension cords before you use them. To do this, you must be able to spot the signs of a damaged cord.
Check that there is no exposed wiring on either end of the cord near the plugs; this damage can easily occur when extension cords are pulled out of a socket. Next, inspect the length of the cord for any nicks, crimps, or melted sections in the insulation. If the ground prong has been removed from the extension cord, it is no longer safe to use even if the rest of the cord appears to be in good condition.
Extension cords are highly convenient for temporary use in spots where you can't reach an outlet, but they are only safe if they are used correctly. For more safety tips and all of your electrical repair and maintenance needs, count on the team at Express Electrical Services !
