Can Extension Cords Get Wet?

Extension cords should not be exposed to water or moisture, as this can pose significant safety risks and damage the cords. Here's what you need to know:

1. Electrical Hazards

Water and electricity do not mix well. When extension cords come into contact with water or moisture, they can become a conductor of electricity. This increases the risk of electric shock and fire hazards, particularly if the cord's insulation is compromised or if it has exposed wires. It's essential to be aware that water, even in small amounts, can compromise the safety of extension cords. This is why it's crucial to take precautions and avoid exposing them to moisture.

2. Damage to the Cord

Water can damage the extension cord's insulation, rendering it unsafe for use. Moisture can corrode the internal wires and connectors, leading to a loss of conductivity and creating a hazard. If the cord becomes wet, it should be thoroughly dried before use. Damaged extension cords are not only dangerous but also inefficient. Once the insulation is compromised, the cord may no longer be fit for use, and it may need to be replaced. This can be an additional cost and inconvenience, emphasizing the importance of preventing exposure to water.

3. Safety Precautions

To ensure safety when using extension cords outdoors or in potentially damp environments, consider the following precautions:

• Use outdoor-rated extension cords designed to withstand exposure to the elements. They have additional insulation and protection to reduce the risk of moisture damage. Outdoor-rated extension cords are specifically designed to resist moisture and other environmental factors. They are more durable and better equipped to handle the challenges of outdoor use. When using extension cords outdoors, especially during the holiday season for lighting displays or yard equipment, outdoor-rated cords are a must to ensure safety.
• Keep extension cords elevated to prevent them from sitting in puddles or wet areas. Use cord clips, stakes, or suspension systems to secure cords off the ground. This practice ensures that the cords remain dry and untouched by any water that may accumulate on the ground. Elevating extension cords also minimizes tripping hazards and prevents them from being damaged by water or debris on the ground.
• Use weatherproof covers for outdoor outlets to protect the connection points from moisture. Ensure that connections are secure and covered adequately. Weatherproof covers for outdoor outlets are a crucial component of safety when using extension cords outdoors. These covers shield the outlets and the connected plugs from rain, snow, and other sources of moisture. They help keep the electrical connections dry and safe, preventing potential hazards and electrical malfunctions.
• If using extension cords outdoors, protect them with a conduit or cord cover to shield them from rain, snow, or other sources of moisture. Conduits or cord covers provide an added layer of protection for extension cords in outdoor environments. They create a barrier between the cords and the elements, ensuring that they remain dry and free from moisture-related issues. These protective measures help maintain the integrity of the extension cords and keep them safe for use.
• Always unplug extension cords when they are not in use. This prevents electrical current from flowing through them and reduces the risk of accidents or damage. Unplugging extension cords when not in use is a simple yet effective safety practice. It not only conserves energy but also reduces the risk of electrical hazards. When extension cords are left plugged in, they are still connected to a power source and pose potential risks, especially if they are exposed to moisture or other adverse conditions.

4. GFCI Protection

Consider using ground fault circuit interrupter (GFCI) outlets or extension cords with built-in GFCI protection, especially in areas where water exposure is more likely. GFCIs can quickly detect electrical imbalances and cut off the power supply, reducing the risk of electrical shock. Ground fault circuit interrupter (GFCI) outlets and extension cords provide an added layer of protection against electrical shock. These devices are designed to quickly detect any imbalances in electrical currents, such as those that occur when there is a short circuit or a ground fault. When a GFCI senses such an imbalance, it automatically cuts off the power supply, minimizing the risk of electric shock. GFCIs are especially important in areas where water exposure is more likely, such as kitchens, bathrooms, and outdoor settings where extension cords may be used for lighting and equipment.

In summary, extension cords should be kept away from water and moisture to ensure safety. Using outdoor-rated cords, elevating cords off the ground, protecting outdoor outlets, using cord covers, and employing GFCI protection can help reduce the risks associated with using extension cords near water-prone areas. These precautions not only enhance safety but also prolong the lifespan of extension cords, saving you money and ensuring reliable performance.
