Daisy-chaining or linking multiple extension cords together is not advisable, as it can create safety risks and potential hazards. Here are some reasons why it's not recommended:

1. Overloading the Cords

When you connect multiple extension cords in a series, it increases the overall length of the electrical path. This can lead to voltage drop, especially if the cords are too long or have a lower wire gauge. Voltage drop can reduce the effectiveness of your connected devices and potentially lead to overheating.

2. Overheating and Fire Risks

Connecting too many extension cords in a chain can lead to overloading. Overloading can cause the cords to overheat, potentially creating a fire hazard. Overheating extension cords are a common cause of electrical fires.

3. Increased Tripping Hazards

Daisy-chaining extension cords can create a tangle of cords that pose tripping hazards, both indoors and outdoors. Tripping over extension cords can lead to injuries and accidents, making it an unsafe practice.

4. Difficulty in Monitoring Load

When you link multiple cords, it can become challenging to monitor the load on each cord. Overloading may not be immediately apparent, increasing the risk of overheating and electrical hazards. Using a single cord with the appropriate load capacity is a safer and more manageable solution.

5. Manufacturer Recommendations

Many extension cord manufacturers recommend against daisy-chaining multiple cords. Their guidelines and instructions typically advise users to avoid this practice due to the associated safety risks.

6. Safer Alternatives

Instead of linking extension cords together, consider using a single, longer extension cord that matches your needs. This eliminates the risk of daisy-chaining and helps maintain electrical safety. If you need to power multiple devices, consider using a power strip with surge protection, designed for this purpose.

In summary, it is not advisable to link multiple extension cords together. Daisy-chaining extension cords can lead to overloading, overheating, fire risks, tripping hazards, and difficulties in load monitoring. To use extension cords safely, choose the right cord length and capacity, and avoid unnecessary connections between multiple cords.
