How Industry Experts Choose the Right Electric Cord for Their Needs 


For an amateur, any extension cord may be good for all home uses and needs.  

However, for experts, there is a need to be specific about an extension cord designated for a particular use. This is due to the risk of not selecting the right for the job.  

Now that you know that not all cords are perfect for all uses, how do you choose the right one?  

Remember, with the right extension cord, your deceives are safe from short-circuiting, and the safety hazards are minimized.  

Before you go to the store to get one, how about you decide on the specific uses and needs? With this in mind, you should stay strong to get one.  

Alternatively, the store operators can help you select one that matches your needs. Still, you need expert knowledge to choose the ideal extension cord.  

So, let’s get into how experts select the best extension cord for indoor and outdoor needs.  

The Suitability For Indoor And Outdoor Uses 

The first consideration when buying an extension cord is whether to use it for outdoor and indoor needs.  

Remember, the extension cord used indoors can never be used outdoors and vice versa; hence, there is a need to consider the most suitable one for every need. Even if the extension cord is suitable for the outdoors, there is a need to select the perfect one for the role, i.e., heating, welding, grinding, etc.  

Whether you buy in-store or online, you can get different types of electric cord; therefore, you must decide on the most suitable one.  

When selecting a suitable one, consider the number of prongs, insulation, labels, energy ratings, etc. Indoor extension cords supply a limited amount of energy, hence making them unsuitable for outdoor needs.  

The Plug Configuration 

The extension cord plug configurations simply mean the number of prongs on the plugs. These prongs have a significant role in energy regulation and safety; hence, you should pay attention.  

An indoor extension cord can have double prongs or sometimes three prongs. However, the extension cord must have three prongs for outdoor needs due to the need for extra safety. 

The devices you want to use will also determine your needed plug configuration. If the device requires a three-prong plug, then that is what you get because such devices would need the ground wire. Failure to do so will lead to short-circuiting and, over time, can damage the device.  

You can use a two- or three-pug extension if a device requires a two-prong plug. Finally, stick to the three-prong plug extension for outdoor uses due to the energy requirements for outdoor equipment to function.  

Power Requirements 

Every device plugged into the extension will require the extension to provide the needed energy. Once you understand the amount of energy your devices need, you can decide the best extension based on the energy ratings.  

If you are still determining this, here is a guideline: normally, indoor power extension cords that supply about 25 amps and above should be on. Consider an extension cord of about 5 to 16 amps for outdoor use.  

Despite the general category, it takes time to determine the specific wattage needs, especially for outdoor equipment, which can significantly vary in energy needs. A 25-amp extension cord can serve all indoor devices without risks or accidents.  

They are also suitable for connecting multiple devices due to their low energy consumption and needs.  

Also, one of the ways to know the key differences is the length. Normally, the outdoor cords seem to have a longer extension cord to boost flexibility and supply the needed energy. The indoor ones tend to be shorter, with the longest being about 25 feet.  Article Source: https://99math.net

Extra Safety Features 

You have heard of how extension cords can be the biggest safety hazard around the home or indoors. Therefore, when selecting one, pay attention to the safety features embedded within the cord.

The outdoors faces significant risks from friction, heat, cold, and other environmental conditions. The indoor area faces risks like water spillage, overloading, and children inserting objects into the cords. To use the outdoors safely, pay attention to the labels on the cords.  

These labels should be T, E, O, and W. W and O mean that the cord is whether and oil resistant, respectively. This means you can use them in any environment without being affected by external conditions. The Os are perfect for garages, factories, warehouses, and outdoor repairs involving oils and asphalt. 

T means the cord has a thermoplastic cover, while E means an Elastomer or Thermoplastic Elastomer Rubber insulation layer. They are ideal for protecting them from extreme heat and friction and securing the inner cable from abrasion.  

For safety, outdoor cords should have at least two or three labels. Insulation can also protect you from voltage loss even for longer distances or affect energy fluctuations, leading to sudden fires. 

The indoor cables should be labeled S and J. J means they are suitable for junior services, and S means that they are flexible for general services, i.e., powering all indoor gadgets. For indoor ones, also pay attention to extra features like the GFCI, which acts as a circuit greater in the event of sudden power surges, which can destroy all your household equipment.  


Before you decide on the perfect extension cord, consider why you need it, i.e., indoors or outdoors.  

Next, focus on the ratings and labels to ensure they are perfect for other needs and supply the energy needed.  

Finally, you can focus on other features like length, safety, features, and number of prongs.
