Whilst extension cords might seem as a supplementary item in contrast to the electrical appliances there is an immense need of choosing these wisely, depending on the power requirements alongside confirmation of safety standards should be heavily considered while purchasing an Extension cord. Here we have jolted down few points which could help you find the best extension wires for your appliances.

How to Select a Good Extension Cord wire? What aspects to consider while buying?

Choosing the appropriate Design

An extension cord regardless of their usage always features a jacket, which is basically treated as a safety mechanism protecting the cord wires from overheating or melting eventually. Jackets are either Round or flat faced.

Flat faced extension cords facilitate low power appliances or mundane indoor home appliances. The jackets are usually made of plastic like cover for regular usage within home setting

Extension cords secured with Round shaped jackets are basically made to resist heavy duty appliances and the heat generated in result of powering heavy duty appliances. This could include outdoor machinery or any other electrical appliances for specialized jobs.

Focus on the length.

Always be considerate of the fact that not all guesses need to hit the bull’s eye neither a very neck to neck comparison always bears a fruit. Practicality is another aspect of importance while choosing an Extension Cord’s Length. Always choose a cord with that of an extended length than you actually thought you would be needing, since few extra inches are not likely to disrupt the functioning of the cord where as on the contrary excessive pressure on a straightened or short cable could induce chances of breakage.

Choosing the Right Size

Also this has to be considered that shorter cable wires are much likely to conduct a larger amount of current with effectiveness as compared to longer cords.

Consider Flexibility

Cords that are usually of moldable nature are way more easier to preserve and also confining them to lesser spaces is much more feasible than that of a stiff one. The flexible cords are less likely to bear any significant harm when positioned in smaller spaces.

Maintaining a feasible environment

An extension cord acts as medium between the electronic infrastructure and the electric gadgets. First and foremost Extension cords that are meant for indoor setting use bear a lighter threshold to voltage requirements, Hence only low gear gadgets such as cell phones, laptop chargers, lamps or bulbs should be attached with Extension cords of such types. Also focusing on safety is not an internal process solely required by the manufacturers. It is also crucial for the consumers to maintain safety. Over heating is a highly prevalent issue when it comes to Extension cords. Over covering or purposely concealing them while abstaining heat to pass through the relevant channels could result in overheating of wires and a possible electrocution.

Identifying the correct Denomination

Mostly extension Cord manufacturers dedicate a series of Letters to segregate the features and manufacturing style of the cords. This helps maintain their utilization in the best possible settings I.e., Indoor and Outdoor with difference suited appliances.

The categorization is as follows

J- Cord featuring standard resistance and insulation.

O- This classification of cord is determined to be oil impenetrable.

S- Cords for generalized use relevant in almost all common settings and compatible with most mundane electronic devices.

W- this certain classification of cords is generally given a go ahead for outdoor use indicating these are compatible with most appliances of outdoor usability.

Understanding the Science of Gauge Numbers

Extension Cords are also differentiated on the basis of AWG “American Wire Gauge” numbers allocated to them. For instance, a cord with lower gauge number is much likely to be secure for use since lower the Gauge number thicker becomes the wire quality. Thicker wire promotes a much efficient insulation than thin gauge wires.

Focus on Prong Outlets

Number of Prong Outlets are detrimental in choosing the right Extension cords in terms of Usage. Usually available in Three Prong outlets and two prong outlets version, the former is well suited for powering up home appliances whereas the latter is well suited for powering up small device chargers.

Evaluating Ampere Rating.

Extension cords usually bear an adequate Ampere rating establishing the amount of power the cord could actually absorb. A cord claiming a higher ampere rating consequentially means it could handle heavy duty appliances. In general, a majority of extension products are manufactured with an ampere rating of 13 amps.


Q. What are the best possible ways to elongate the functioning life of an extension Cord?

A cord could be best maintained if its supposedly kept in a dry and clean environment as excessive moisture or dirt could bring pollutants to enter inside the wires. Secondly the longevity of such products is also tempered with if the load management is not done accurately.

Q. What are surge protectors and how Are these relevant?

These protectors are minute devices installed in cord wires in order to eradicate the possibility of overheating and also provide security in environments of extreme voltage fluctuation or power breakdowns.

Q. What are usual price points of Good Extension Cord Wires?

Pricing basically starts from 8$ to anywhere up to 90$. The price point is basically determined owing to factors such as cord length, safety protocols and brand’s pricing strategy mainly. Cords that are targeted to achieve outdoor usage purposes are most likely to be priced slightly higher than that of indoor ones since they require strict safety control and more investment of resources by the manufactures. . Outdoor cords are usually expensive due to their nature of their output.

Q. What is the difference between a Three-Pronged Outlet and Two Pronged one?

The basic differentiation lies in the nature of their usage. Two pronged models could well accommodate small scale devices such a Phone charger, laptop chargers or any run of the mill product that does not require a lot of electrical power. However, the three-pronged plug is mostly utilized where the power requirements are usually higher than that of two-pronged cords.
