Why I Always Use a 2 Prong 3 Prong Extension Cord

As someone who has moved around a lot and lived in different types of housing, I have come to appreciate the necessity of having a 2 prong 3 prong extension cord. This type of extension cord has two regular prongs and one additional round prong, which is commonly known as the ground pin. Here are a few reasons why I believe this type of extension cord is necessary.

Firstly, safety is the most important reason for using a 2 prong 3 prong extension cord. The additional ground pin provides an extra layer of protection against electrical shocks. This is especially important in older buildings where the wiring may not be up to code or may be faulty. By using this type of extension cord, I feel more secure knowing that my appliances and electronics are grounded properly.

Another reason why I always use this type of extension cord is versatility. Most modern appliances and electronics come with three-prong plugs that require an outlet with a ground pin. However, in older buildings or in outdoor settings, it is not uncommon to find outlets with only two slots for prongs. In these situations, having a 2 prong 3 prong extension

My Buying Guide on ‘2 Prong 3 Prong Extension Cord’

Extension cords are a must-have in any household or workspace. They provide convenience and flexibility when it comes to powering your devices and appliances. However, not all extension cords are created equal. Some have two prongs, while others have three. In this buying guide, I will walk you through everything you need to know about 2 prong and 3 prong extension cords so that you can make an informed decision when purchasing one.

What is a 2 Prong 3 Prong Extension Cord?

A 2 prong extension cord, also known as a non-grounded or ungrounded extension cord, has two flat blades on the plug and outlet ends. It is designed for use with two-pronged appliances and devices that do not require grounding. On the other hand, a 3 prong extension cord has an additional round or U-shaped pin for grounding purposes. This type of extension cord is suitable for three-pronged appliances and devices that require grounding for safety reasons.

Consider the Length and Gauge

The length of the extension cord is an essential factor to consider when purchasing one. You need to ensure that it is long enough to reach your desired power source without stretching or pulling on the cord excessively. Additionally, pay attention to the gauge of the cord. The lower the gauge number, the thicker the wire and higher its capacity to handle more electrical current.

Check for Safety Features

Safety should be your top priority when buying an extension cord. Look for safety features such as polarized plugs, which have one prong wider than the other to prevent improper insertion into outlets; childproof sockets, which have built-in shutters to prevent children from inserting objects into them; and surge protection, which protects your devices from power surges.

Determine Your Power Needs

Before purchasing an extension cord, consider how much power you will be using through it. If you plan on connecting high-powered appliances such as refrigerators or air conditioners, opt for a heavy-duty extension cord with a higher gauge number to handle more electrical current safely.

Tip: It is recommended not to exceed 80% of an extension cord’s maximum wattage capacity.

Look for Outdoor Use Cords

If you plan on using your extension cord outdoors, make sure it is specifically designed for outdoor use. Outdoor extension cords are made with more durable materials that can withstand harsh weather conditions such as rain and extreme temperatures.

Tip: Never use indoor extension cords outdoors; they are not built to withstand outdoor conditions and can pose a safety hazard.

Consider Your Budget

The price of an extension cord can vary depending on its length, gauge, safety features, and brand. Before making a purchase, decide how much you are willing to spend based on your specific needs and budget constraints.

Tip: Avoid purchasing cheap or low-quality extension cords as they may not meet safety standards and can cause damage or accidents.

Conclusion

In conclusion, when shopping for a 2 prong or 3 prong extension cord, it is essential to consider factors such as length and gauge, safety features, power needs, outdoor use capabilities, and budget constraints. By keeping these factors in mind and making an informed decision based on your specific needs, you can ensure that you purchase a safe and reliable extension cord that will meet all your power needs effectively.
