Can I Plug My Electric Heater Into An Extension Cord? Here’S The Shocking Truth

Electric heaters provide warmth and comfort during chilly seasons, but their high power consumption raises concerns about electrical safety. One common question that arises is whether it’s safe to plug an electric heater into an extension cord. This blog post aims to delve into this topic, exploring the potential risks and providing safe alternatives.

Electrical Hazards and Extension Cords

Extension cords are designed to extend the reach of electrical outlets, but they can pose risks if not used properly. Overloading an extension cord can lead to excessive heat buildup, potentially causing a fire. Electric heaters draw significant power, which can exceed the capacity of most household extension cords.

Power Consumption and Cord Ratings

The power consumption of an electric heater is measured in watts (W). Extension cords are rated for a specific amperage (A), which corresponds to the maximum current they can handle. To determine if an extension cord can safely power an electric heater, you need to calculate the amperage draw of the heater using the following formula:

“`
Amperage (A) = Power (W) / Voltage (V)
“`

For example, a 1500W heater operating on a 120V circuit would draw 12.5A.

Choosing the Right Extension Cord

If you do decide to use an extension cord with an electric heater, it’s crucial to select one that is rated for the heater’s amperage draw. Look for extension cords with a gauge size of 14 AWG or 12 AWG, which can handle higher currents.

Alternative Heating Options

In some cases, using an extension cord with an electric heater may not be feasible or safe. Consider these alternative heating options:

• Gas heaters: Gas heaters provide warmth without relying on electricity, making them a safer option in areas where extension cords are not recommended.
• Central heating: If your home has central heating, you can use it to heat the entire space evenly, eliminating the need for portable heaters.
• Space heaters: Space heaters are designed to heat specific areas of a room and consume less power than electric heaters, reducing the risk of overloading extension cords.

Safety Precautions

If you choose to use an extension cord with an electric heater, follow these safety precautions:

• Inspect the extension cord: Before each use, check the cord for any damage, fraying, or loose connections.
• Keep cords away from heat: Avoid placing extension cords near heat sources, such as electric heaters or stoves.
• Unplug when not in use: When not in use, unplug the electric heater and extension cord from the outlet.
• Use a surge protector: A surge protector can help protect your heater and other electronics from power surges.
• Never overload the cord: Do not plug multiple appliances or devices into a single extension cord, as this can overload the circuit.

Frequently Asked Questions

Q: What is the maximum amperage an extension cord can handle?
A: Extension cords are typically rated for 15A or 20A. Check the packaging for the specific amperage rating.

Q: Can I use a 16 AWG extension cord with a 1200W heater?
A: No, a 16 AWG extension cord is not rated for the amperage draw of a 1200W heater. Use a 14 AWG or 12 AWG cord instead.

Q: How often should I inspect extension cords?
A: Inspect extension cords before each use and discard any damaged cords immediately.

Q: Can I plug a space heater into a power strip?
A: Yes, as long as the power strip is rated for the amperage draw of the space heater. However, it’s best to avoid plugging multiple high-power appliances into the same power strip.

Q: Is it safe to use an extension cord with a built-in circuit breaker?
A: Yes, extension cords with built-in circuit breakers can provide additional safety by automatically tripping if the circuit is overloaded.
