5 Features To Look For When Buying The Perfect Extension Cord

As you might already know, extension cords are usually used to extend the electrical circuits of a home or workshop when a lamp, appliance, or tool has a cord that is too short to reach the desired position. Most individuals keep numerous extension cords on hand for just this purpose. What is sometimes overlooked, however, is that these extension cords must be of adequate capacity for the power demand placed on them. 

Read on to discover more about extension cord amps, wattage, and safety precautions when using them.
 

How Do Extension Cords Operate? 

An extension cord connects a short power cord to a power outlet and transfers power from the outlet to the device. They come in various lengths, ranging from 2 to 100 feet. Connecting two extension cords is not recommended since it may result in a decline in amperage. 

An extension cord consists of three parts: the socket (female), the cord, and the plug (male). The socket is where you plug the wire from a device or appliance; the cable conducts the current, and the plug connects to a wall outlet. Moreover, the cord's thickness determines how much electrical current it may safely carry. 

Make sure a three-prong plug connects to a three-prong power outlet. A three-prong outlet can accommodate a two-prong plug. 

That said, let’s review some of the features you must look for before purchasing an ideal extension cord. 

1. Ratings 

Extension cords are rated based on the amperage and wattage they can safely transport, both of which are determined by the wire's gauge. The amperage rating for each extension cord should be indicated on a tag attached to the cord. However, this label may not always be present or visible. 

When selecting an extension cord, it is critical to consider the wattage and amperage required by the item or appliance attached to it. In most circumstances, a standard household extension cord is sufficient for simple items such as lamps, radios, televisions, and other electronics. These basic extension cables typically use 16-gauge wire. 

Things become more complicated when you use an extension cord to power motorized devices or when they generate heat. These items have a much higher electrical load, so lightweight extension cables should not be utilized. 

Longer extension cables have higher electrical current resistance, increasing the risk of overheating. A 5-foot-long heavy-duty extension cord powering a table saw rarely overheats, whereas a 50-foot-long extension cord with the same wire gauge may be undersized for the job. 

2. Matching Extension Cord to Load 

Extension cords should be rated for loads that are at least equivalent to, and ideally larger than, the needs for running a tool efficiently. Besides, extension cord lengths of 50 feet or fewer can be utilized; however, those that run longer than 50 feet should use the next heavier-sized cord to account for voltage drop caused by the wire's inherent resistance. 

Colors do not reflect the amount of power they can transmit. They are primarily employed for aesthetics. In heavy-duty environments such as construction sites, bright yellow or orange cords are often thicker gauges. Black or white wires are typically used in homes to mix with other electrical cords. 

3. Length 

Power extension cables are available in a variety of lengths, from one foot to 100 feet. The extension cord's length may appear arbitrary, yet it plays an important function in supporting effective electrical current flow. Although purchasing a longer extension cord than you require seems a good idea, electric resistance increases with distance from the power source. Reduced power, in turn, can overwork an electric device's motor, resulting in device damage. 

Purchase a short power cord; you may need to connect many to extend the power needed here. However, this is not recommended because it could start an electrical fire. 

As a result, determining the appropriate extension cord length entails striking the right balance. So, opt for an adequate length, but do not purchase an unnecessarily long extension cord. 

4. Outdoor Applications and Weather Resistance  

Not every extension cord is appropriate for outdoor use. Outdoor-rated cords are made of weather-resistant materials such as rubber and vinyl to increase endurance. This is in addition to strengthened insulation and waterproof connectors, which allow them to tolerate sunshine, moisture, and temperature changes. When utilizing electrical tools or appliances outside, always use an extension cord that has been labeled for outside usage. 

In general, spending a few dollars more on an oversized extension cord is preferable to being unprepared. It may be overkill for something as simple as a phone charger, but the increased longevity will come in handy if you need to use it with more demanding equipment in the future. 

An extension cord should not be used to power a gadget that draws a substantial amount of current. However, if you must use an extension cord in an emergency, ensure it is thick, short, and provides a high voltage to avoid motor or part damage and ensure optimal functioning. Even better if it's adaptable enough to work in several environments. By selecting the appropriate extension cable for your needs, you can power your equipment with confidence that its components will not wear out or create a fire. 

5. Product Certification 

How do you protect the safety of property and lives? The answer is product certification. Nema 5-15r connections and matching plugs from reputable manufacturers are either UL-certified or ETL-listed. It further signifies that the cord meets or exceeds the safety criteria established by regulatory agencies such as OSHA. 

Also, only buy from reputable manufacturers. Reading internet reviews to find out what others think about the brand would be wise. Avoid using cheap marketing phrases like "heavy-duty" or "industrial grade." 

In the end! 

Purchasing the correct extension code is the first step in safeguarding your home and workspace from electrical hazards. However, other safety precautions and adequate extension cord maintenance are critical. Finally, even the greatest extension cord cannot replace permanent wiring.
