When deciding which product will be the best, the features to look for can be tough. Hence, we will guide you through all the specifications required while making the right decision.

What is an Extension Cord?

An extension cord, also known as a power extender or extension lead, is an electrical power extension cable that is longer and is flexible that has a plug on one end and one or more than one socket at the other end. Its main function is to power an electrical appliance that doesn’t reach the outlet. Longer power cords lead to more electrical resistance and transmit comparatively lesser power to devices connected to the outlet. Therefore, it is better to use an extension cord of the appropriate length to decrease the power loss.

How to Fix an Extension Cord?

An Extension Cord can be fixed by following some easy steps.

  1. Make a cut over the outer jacket of the cord by using a utility knife. Make sure that you will not have a deep cut in the cord. This can break the wire itself.
  2. Cut and Strip the wire. The length of the cut should be as per the length mentioned in the strip gauge.
  3. Before screwing the wire into a plug, make sure you twist the wires tight. For the wire concerned, make sure the black wire goes into the golden screw, white into silver and green into the green. Ensure you will not cut the insulation jacket as it will prevent the wire from tearing during the outlet.
  4. For the last step, close the plug and screw it tightly to fix the cord tightly in it.

How to Roll Up an Extension Cord?

An Extension Cord can be rolled up by following these steps:

  1. For the first step, connect the male and female ends of the extension cord.
  2. Now, make an Overhand Knot at the end where you connected the two male and female ends.
  3. Make successive knots following the first one. To make a successive knot, pull your hand through the overhand knot loop and grab the two strands of cord to make a new knot.
  4. When you reach the end of the cord, just tie off the knot by pulling it through the last loop. This will make another overhand knot at the end.

What Gauge Extension Cord Do I Need?

  • The 100-foot-long extension cord should be used if the current draw lies within the range of 10A-20A, provided the voltage drop is at most 5.00%. The minimum wire gauge for this extension cord ranges from 10 gauge – 12 gauge.
  • A 50-foot extension cable is recommended for current draw ranging between 10A-20A, provided voltage drop is at most 4%. The range for minimum wire gauge is 12-14 gauge, whereby 12 gauge is for 20A current draw and rest of current, 14 gauge.

Types of Extension Cords

Two-Prong Cords

Two-prong plugs are not safe as compared to three prongs. The two wires are connected to them, of which one gets connected to the hot and the other to the neutral wire in the extension cord. The biggest disadvantage of two-prong cords is that no connection is attached to the ground wire, and hence, not suitable for high-voltage appliances.

Three-Prong Cords

Three-prong plug extension cords are appropriate for outdoor uses. The third prong is attached to the ground for carrying high-voltage. They are safer and perfect for use with electrical appliances that require high power. Thus, it is better to search for an extension cord with three-prong plugs so that you can use it anywhere without any hassle.

  • Indoor extension cables are available at most 25 feet in length, whereas outdoor extension power cords come in a length of 150 feet at least. The difference in length availability is essential, especially when you need to determine the size of the gauge wire cord.
  • Indoor and outdoor extension cord differs based on plug type too. Most indoor extension power cables have two-prong plugs, whereas outdoor power extension cords are available with three-prong plugs.
  • Indoor cord generally supports lower amperage flow, whereas outdoor extension cord has comparatively higher amperage rating.

  • Check and make sure all the connections are tight and secure before plugging them into a power source.

How to Protect Outdoor Extension Cord from Rain?

Protecting an outdoor extension cord from rain is crucial because moisture can affect its performance and quality. It is better to disconnect the cord before the rain as it is essential for your own safety. The outlet must have a weatherproof coating or cover to remain protected from rain and other odd situations. It has to be done to the other end of the cord as well. You can make use of plastic bags for accomplishing this purpose.

Features to Consider While Buying Extension Cord

It is always preferable to choose a perfect product for your applications. However, in the available market with abundant products, choosing a perfect one is sometimes tough. So to make your shopping easy, here are a few main considerations of an extension cord.


When you are purchasing an extension cord, it is suggested that you go for the cord whose length is a bit longer than your required one, i.e., you should opt for the cord next in length. Plugging into each other, these extra multiple cords increase the resistance between the outlet and you’re intended. Target which you want to power. Not only this, purchasing a longer-length extension cord can prove to be one investment that you can utilize beneficially in your future projects as well.


Aside from the length, thickness inside the extension cord also helps to determine how much power cord can safely carry. Moreover, thick wires transmit more power safely over long distances. Any cord at a big-box store should meet the minimum requirements, enabling them to run low-power gear like lights, battery chargers, or a stereo.

Wire gauge

In the United States, the thickness of the cord is determined through the gauge or what they call AWG, aka American Wire Gauge. AS per AWG charts, the larger the numbers, the smaller the wires are, which will eventually carry power. The cord with a measurement of 14 AWG, which is recommended, is the thinnest, provided lengths of cords are only 25 feet or shorter whereas, the thicker 10 AWG is probably the thickest gauge you’ll ever find in any store selling extension cord.

Ability to handle standard power

it is recommended that you better skip indoor/outdoor extension cords rated ranging between 10 A and 13 A. Instead, you should rather get one rated for at least 15 A., And if your intended cord doesn’t list a maximum amperage, it is suggested that you should skip it entirely. Using the extension cord starting from 15A rated will allow you to plug in any household tool or equipment. They are fit for 15 A breakers or fuses, which are usually found in most residential electrical panels, which cut off the power before the cord is pushed beyond its limits.


Flexible Cords are easier to stretch across the workspaces, easier to coil up and store properly, and less frustrating when fitting them in tight spaces. It’s hard to choose which cord one should use and make the work pretty easy when cords are tightly wrapped in their packaging on a shelf. Without uncoiling them and drawing them off the aisle, the only way to ensure that you get a flexible cord is to search for one made for lower temperatures.

Number of outlet ends

It’s no hidden fact that with an extension cord with few extra outlets fixed on end known as banana tap, people usually look forward to using such extension cords. And if you’re looking for a durable cord to run tools, equipment, work lights, or other power hogs, it is recommended that you avoid them at all costs because they’re affinitive to go overload easily. For anything requiring serious power or even general-purpose cords that you hope to have on hand for several years to come, you need to stick to one outlet per cord and per piece of equipment.
