Uncovering the Benefits of Heavy-Duty Extension Cords 

extension cord benefits


Anytime a gadget, appliance, or other electrical device needs power but is located too far from an available outlet, an extension cord is the most popular, quick, and easy solution. These top-rated insulated and flexible devices can be found in any retail establishment selling various goods, including hardware and home supply shops.

Hence, extension cords, consisting of an outlet, plug, and a length of flexible, insulated cabling, are utilized in most households, businesses, and factories, as well as in the construction industry.

However, the standard extension cable has become one of the most overused and neglected pieces of hardware despite its usefulness in bringing power where and when required. They are frequently utilized to supply current under situations beyond their design, making them more prone to failure than fixed wiring because their capacity can often be exceeded.

In a nutshell, heavy-duty extension cords are essential for any organization or household that uses electrical machinery. Once put to good use, they provide several advantages covered in this guide.

Types of Extension Cords


They can be categorized as light-duty, regular-duty, or heavy-duty based on the maximum load intended for the uses of extension cords in each category.

  1. Light-duty Extension Cord Ratings

The 18 AWG, 16 AWG, and 14 AWG gauges are typical for light-duty extension cords. The estimated length of the cord determines the gauge used. The gauge number increases in proportion to the length's decreasing size. When the cord is no longer than 25 feet, select 18 AWG wire. Likewise, 16 AWG is the recommended gauge for cables up to 50 feet long. Finally, the 100-foot length necessitates the use of 14 AWG.

  1. Medium-Duty Extension Cord Ratings


16 AWG to 12 AWG are the sizes that can be used for medium-duty extension cords. Cord lengths supported by the 16 AWG, 14 AWG, and 12 AWG variants are 25, 50, and 100 feet, respectively.

  1. Heavy-duty Extension Cord Ratings

Power tools like space and other heaters require heavy-duty extension cords. These cables can withstand up to 15 Amps of current when properly used. They come in sizes from 14 AWG down to 10 AWG. Wire gauges range from 14 AWG for 25 feet to 12 AWG for 50 feet to 10 AWG for 100 feet.


Light-duty vs. Heavy-duty Extension Cord

Extension cables with a smaller load capacity may cost less than heavier-duty counterparts. They may break under pressure and aren't designed for prolonged usage.

Extension cables with a heavy-duty rating are often intended for use outside. Because the wires in them are thicker than those found in standard extension cords, they are more resilient to prolonged use. Thanks to their robust design, they can withstand heavy machinery's elements and pressure. Having covered the differences between these two, let's take a closer look at how is an extension cord assembled for safe use for the best benefits.

What is a Heavy-duty Extension Cord?

Heavy-duty extension cords are designed to accommodate currents of 10 to 15 amps. You will always find these 10 gauge extension cords to be grounded extensions with three holes on the plug for grounded equipment.

Such extension cords are meant to carry high voltage primarily to heating appliances and tools that require as much as 15amps of power.

Benefits of Heavy-duty Extension Cords

Here are some advantages of heavy-duty extension cords for your home and office electronics.

  1. More Effective

In contrast to standard extension cords, heavy-duty cords feature higher gauges, allowing them to carry more electricity.

Because they are constructed with such high-quality wires, they won't quickly overheat, even after continuous use. They are designed to withstand heavier loads, perfect for high-powered appliances and gadgets.

  1. Durability‍

It is imperative that you give longevity some thought when shopping for a heavy-duty extension cord. Compared to regular extension cords, heavy-duty ones are superior in reliability and durability.

The wires are excellent for any situation because of their thickness, which allows them to endure being run over by trucks or trodden by people.

  1. Capable of Functioning in Any Climate

Outdoor extension cords are heavily insulated. This makes them more reliable in both hot and cold climates. Also, the inside wire can withstand higher voltages than are permitted by conventional circuit breakers, making it suitable for use with a wide variety of electronic devices. It also prevents any damage to your equipment.

When shopping for switch extension cords, one of the most common concerns among customers is the product's ability to withstand wet and snowy conditions, mainly if the cords are used indoors.

You shouldn't worry about heavy-duty extension cables falling short in the rain or any environment because their thicker jackets shield them from damage caused by light, chemicals, scratching, etc.

The letter "W" printed on the jacket of some extra-heavy-duty extension cables indicates that they are weather-proof and safe from electric shock.

The cables are also adaptable, allowing them to be utilized in various environments, structures, or expansive stretching yards without concern for corrosion or changing temperatures. They are resilient enough to handle demanding equipment and applications in varying climates without failing or catching fire. These switch power cords can also be used for business purposes, such as by professional research groups.

  1. Reduces Costs

Extension power strips are affordable and practical. They don't require much upkeep. All you have to do to power them up is use the appropriate appliances. To avoid the headache of installing new power sockets that are not essential, all you need to do is get the cord, and you will no longer have to worry about these issues.

Cost is one of the things that people mostly think about when picking heavy-duty extension cords. A heavy-duty extension cord may be more expensive initially, but it will save you money.

For instance, investing in a high-quality extension cord can save you money in the long run by preventing the need to replace an otherwise functional electrical item.

Second, although it is simpler to replace extension cords regularly, you can get a single heavy-duty extension cord designed to endure long-term use.

  1. Guarantees Safety

Heavy-duty extensions are discreet, preventing the clutter resulting from tangled wires. These extension cords are handy in homes with many people living there, especially those with young children. They make it such that you are less likely to trip over loose wires. For this reason, it is a good idea to purchase.

Plus, using extension cords with a heavy-duty rating for business operations is necessary to prevent potential risks. That's because nothing beats a heavy-duty extension chord regarding electrical safety.

The heavy-duty extension cord's insulated jackets of superior quality prevent fractures and splits that could expose users to electrocution.

In addition, you won't have to worry about the system becoming overloaded because it was explicitly designed for this purpose. It can power numerous equipment without the risk of starting a fire.

  1. Lengthier Cables‍

The capacity of a heavy-duty extension cord to support longer wires sets it apart from other types. When employing extension cords at work, ensure they have adequate length to reach every area of your workspace.

Heavy-duty extension cords are made so that they can be stretched to massive lengths without losing power. Regardless of the length you require, you can always locate a size that meets your needs. You won't have to deal with coiling up an extra rope or struggling to extend the cord to the place, so there's no need for concern regarding the length.

Disadvantages of Extension Board

Things become more complex when using an extension cord for appliances with motors or generating heat. So you’ll need to know the disadvantages of using extension wires at home. Lightweight extension cables shouldn't be utilized with these items because of their significantly higher electrical demand. The length of the extension chord is another factor that makes the situation more complicated.

When extension cords are longer, the resistance of the electrical current increases, increasing the likelihood that the cord will overheat. While a heavy-duty extension cord at most five feet in length may reliably power a table or saw without overheating, a cord fifty feet with the same wire gauge might not be up to the task.

Furthermore, your pet rabbit has a higher probability of chewing through a live heavy-duty extension cord if you have many of them lying around. This is why you may find ‘do not use extension cord warning in some areas.’

How to Detect a Damaged Extension Cord

So, how often should you inspect an extension cord in active use? It depends on what you’re looking for. Below are some:

  • Slacky or Floppy Cords

You might discover that some of your cords are no longer firmly linked to their plugs if you frequently tug the extension cord from the socket rather than withdrawing the plug. If so, you should get new ones and pull them out by the plug instead of the line.

  • Insufficient Cords

If the length of your wire is insufficient, you may join many cords to get them to the desired area. This might lead to your heavy-duty extensions needing to be fixed and overheated. Rather than splicing together multiple cords, buy one of the appropriate length.

  • Cord Feels Hot to Touch

A cord that feels warm to the touch is carrying too much weight. Most extension cords wear out because they get too hot, which is dangerous. Replace cables that get too hot to the touch immediately before they cause an electrical fire.

  • Torn or Broken Insulation

If you notice any cracks, nicks, cuts, or fraying in your cables, you should replace them immediately. In other words, the protective coating must be repaired or replaced if it has been compromised even slightly.

  • Lack of Safety Certification

The long-term consequences of that fantastic extension cord deal you found could be hazardous. Only purchase cords that the UL has approved. Uncertified cords may not contain the required conductors, posing a safety risk.

  • Cords Operating Above Rating

Ensure the cord you're using is rated appropriately for your inserted device. Check with your neighborhood hardware shop if you need help determining which heavy-duty cord to use.

  • Lacks Crucial Safety Components

There is a possibility that the extension cables you've had since the 1980s are no longer safe to use. So make sure that your cables are equipped with the most recent safety measures, like polarized blades (in which one of the prongs is a bit bigger than the other to ensure that the plug can only be inserted into the outlet using one direction) and a broad plug face that conceals the slots in the outlet. If your cables are outdated, they should be replaced.

If you discover that an extension cord has been damaged, you should not attempt to fix it but rather get rid of it.
