What to Look for in Safest Extension Cords

Important criteria

  • Appropriate length
  • Sufficient wire gauge
  • Durability
  • Certified by recognized safety standards (e.g., UL, ETL)
  • Heaviness of insulation
  • Three-pronged plug

1.) Check the Cord's Rating

Before purchasing an extension cord, it's essential to ensure it is suitable for its intended use. Check the amperage rating of the cord and verify that it can handle the electrical load of the devices you plan to plug into it. For outdoor use, make sure the cord is rated for exterior applications. Choosing a cord with the proper rating reduces the risk of electrical hazards.

2.) Inspect the Quality and Features

The construction of the extension cord should be sturdy and durable to withstand regular use. Look for cords that come with a built-in surge protector or circuit breaker for additional safety. High-quality cords are often equipped with heavy-duty plugs and sockets that resist breaking. A cord with a power indicator light can also be beneficial to easily confirm that power is flowing through the cord.

3.) Consider Cord Length and Flexibility

Select the right length for your needs to avoid daisy-chaining extension cords, which can be dangerous. Longer cords can have a power drop, so choose the shortest length necessary. Additionally, a flexible cord at varying temperatures is advantageous, especially for outdoor or heavy-duty use, as it will be less prone to cracking or breaking.

Questions You Might Ask

The length of an extension cord is critical for safety and efficiency. Choose a cord that is long enough to reach your device without being too long, to avoid voltage drop and potential tripping hazards. It's generally better to use the shortest length necessary for your needs.
The gauge or thickness of the wire indicates its capacity to carry current. The smaller the gauge number, the thicker the wire and the more current it can carry. For most household appliances, a 16-gauge cord is sufficient, but for power-hungry tools or devices, a 14 or even 12-gauge may be necessary. Check the device's power requirements and the cord's rating to determine the appropriate gauge.
No, you should not use an indoor extension cord outdoors. Outdoor extension cords are specifically designed to withstand weather elements like moisture, temperature changes, and UV exposure. They also have a heavier jacket material for better insulation and protection.
A two-prong extension cord has two conductors and lacks a ground wire, making it suitable for basic appliances and electronics without grounding requirements. A three-prong cord includes a ground wire for added safety, reducing the risk of electric shock or fire, and should be used with devices that have a third prong on their plug.
Always inspect cords for damage before use, avoid daisy-chaining cords together, don't run cords under carpets or furniture, and ensure they are completely uncoiled to prevent overheating. Also, make sure they are not a tripping hazard and are rated for the load they will carry. Always follow manufacturer instructions and local electrical codes.

How to Choose the Safest Extension Cord

Navigating the world of extension cords can be tricky, but your safety is paramount. When dealing with electricity, the right choice is crucial to prevent hazards. This guide will walk you through the essential features and safety standards to consider, ensuring you select the safest extension cord for your needs.

Understanding Cord Ratings

Before you dive into purchasing an extension cord, it's important to understand the ratings. Extension cords are categorized by gauge, length, and power handling capacity. The gauge refers to the wire thickness; the smaller the number, the thicker the wire, which correlates to higher capacity to carry current.
Always check the wattage rating of the device you intend to plug into the cord, and ensure it matches the extension cord's rating. Using a cord that's not rated for high power appliances can result in overheating and potential fire hazards. For outdoor use, make sure the cord is labeled for outdoor use, with a 'W' in the rating code.

Material and Build Quality

A robust extension cord has a well-insulated, durable exterior that resists abrasion, moisture, and sunlight. Rubber, vinyl, or plastic are common materials, with rubber often proving to be the most durable and flexible option. A quality cord should feel sturdy in your hands and should not kink or twist easily.
Additionally, look for cords with reinforced ends as they prevent the wires from detaching from the plugs. Cords with a lower gauge are typically higher quality because they have thicker wires and can handle more amperage, reducing the risk of overheating.

Safety Features

Safety should be your number one priority when choosing an extension cord. Features such as a built-in circuit breaker can prevent overloads, and surge protection can protect your devices from voltage spikes. Ensure the plug has a grounding pin (the third prong) if you're using it with devices that require grounding.
One often overlooked feature is a tamper-resistant cover which is especially important in households with children. They help prevent foreign objects from being inserted into the cord's outlets. Also, cords with glowing ends can offer the convenience of finding them in the dark while indicating they are powered and should be handled with care.

Certifications and Compliance

Reputable extension cords will have certifications from independent testing organizations like UL (Underwriters Laboratories), ETL (Intertek), or CSA (Canadian Standards Association). These certifications mean the cord has been tested and meets certain safety standards.
Double-checking for these certifications gives you peace of mind that the extension cord adheres to strict safety requirements. Avoid cords without any visible certifications or those that claim to be 'just as good'. It's a small detail that can make a significant difference in safety.

Additional Considerations

Consider the length of the extension cord you actually need. While it might be tempting to buy a longer cord 'just in case', longer cords can result in voltage drop and power loss, especially if they're not needed. Plan your power source and devices carefully to purchase an appropriately sized cord.
If you're using the cord for power tools or machinery, opt for cords with a twist-lock feature which prevents accidental disconnections. Remember, you're investing in safety just as much as convenience, so choosing the right extension cord matters.
