However, sometimes people choose the wrong cords for their requirements and jeopardize their safety. Moreover, “extension cords are considered to be one of the dangerous electrical devices found in our homes because of improper cord sizing,”- according to the U.S Consumer Product Safety and Commission.

Key Factors to Consider for Selecting the Appropriate Extension Cord
-
1. Types of Extension Cords
Indoor and outdoor extensioncords arehelpful tools. However, indoor cords lack the material that worksasprotective insulation tosafeguardagainst moisture andvarying temperature. Outdoor extensioncords are madeof athicker and more durablelayer of protective insulation, allowing them to withstand a long period in varying temperatures easily.
Along extension cord can hold larger gauges, enabling more current flow through. When it comes to the Indoor extension cords, they cannot accommodate over 25 feet whereas, outdoor cords are available in amuch longer length,over 150 feet.
In addition to this, some appliances need more amperage than others. An outdoor extension cord typically has a higher amperage than an indoor extension cord.
Outdoor extension cords are divided into three categories:
-
Occasional User Cords,also called light-duty extension cords,arelightweight and ideal forindoor applications like running portable fans, electric hedge trimmers,or even holiday lightsthat draw up between (1-13 Amps) power.
-
Frequent Use Cords,also known as medium-duty cords,are designed to handle more extensive toolsand equipmentlikerunning televisions, computers, and other devices that draw between(14-15 Amps) power.
-
Rugged Cords,also called heavy-duty extension cords,are designed for continuous use on job sites,evenin extreme weather. Also, they are appropriate forhigh amperage tools like running chain saws, power drills, or shop vacsdrawing up between (16-20Amps) power.

2. Length of the Cord
Extension cables are available in numerous lengths from10 feet to 100 feet. However,it's ideal to opt for longer cords as they enable the user to makeadjustments without sacrificing the actual length of the cord.
It's always great to choose longer cords over shorter ones that don’tdeliverelectricity to unreachable areas. Except this, long extensioncords are also safer because of less resistance.Usually, there will be a higher electric resistance while connecting multiple cables to get the appropriate place. Such a process reduces the effectiveness andsaves you from more significant problems.

3. Extension Cord Ratings
While choosing an extension cord, ensure to determine the amount of the wattage and amperage drawn by the tool or appliance connected to the extension cord.Small home appliances like television, lamps,or phone battery charger can workwith a standard cord. On the other hand, working with high-power gadgets like electric saws, drills, or dry and wet vacs, requires an appropriate extensioncordsupporting power.
Also, you can research on the internet about recommended wire gauges for the tools and appliances or inquire from the experts to see what works for you.

4. Designation Lettering
Extension cords generally hold a sequence of letters on their insulation or jacket. Consider the following letter while selecting:
-
An "S" cord indicates a flexiblecord and is meant for general use.
-
A "W" shows the cord is designed for outdoor use.
-
An "FT2" cord stands for fire retardant.
-
An "O" cordindicatesthat it’s oil-resistant.
-
A "T" cord jacket is comprised of vinyl thermoplastic.
-
An "E" cord jacket comprises thermoplastic elastomer rubber (TPE).
5.ItemsnotMeantforExtensionCord
Using light or medium-weight extension cords for high power consumption tools and appliances is always dangerous. Following are the things you should never plug into an extension cord:
-
Coffee pots and Irons are considered heat-producing appliancesand draw at least 10-12 amps of current, beyond the limit of most indoor extension cords.
-
Portable heaters are unsafe whenusedwith extension cords as they are portable and requiremovements.
-
Treadmills manufacturers mostly discourage the use of cords with their products. However, if it's not possible to move the treadmillcloser to the outlet, choose a cord that is designed for treadmills.
-
6. Ground Fault Circuit Interrupter (GFCI)
Most extension cords are designed witha built-in ground fault circuitinterrupteror GFCI. The GFCI addsan extra layer of safety sinceit's intended to automatically cut the power of the cords incasea ground fault occurs.
Conclusion
Always ensure to choose a high-qualityextension cord incorporated with GFCI. However, the most important thing to consider is the thickness and length of the cords. Kindly note that extension cords need to get used as temporary electric solutions, so make sure to unplug them when not in use.
