What is light-duty vs heavy-duty cord?
When choosing an extension cord, understanding whether you need a light-duty or heavy-duty one is essential. Each type has its specific purpose, and selecting the wrong one can lead to inefficiency or even safety hazards.
A light-duty cord is designed for small appliances and low power needs, while a heavy-duty cord is built for high-powered tools and demanding applications.
Knowing the differences can help you make the right choice. Let’s explore both types and their applications.
What is the best gauge for a heavy-duty extension cord?
Gauge size determines the power capacity of an extension cord. What gauge is best for heavy-duty applications?
The best gauge for a heavy-duty extension cord is 10 or 12, as these can handle high currents and minimize voltage drop.
Lower gauge numbers indicate thicker wires, which are better for heavy-duty tasks.

Gauge Comparison
| Gauge | Maximum Amps | Typical Use |
|---|---|---|
| 16-Gauge | Up to 13 amps | Light-duty, small appliances |
| 14-Gauge | Up to 15 amps | Moderate-duty, indoor tools |
| 12-Gauge | Up to 20 amps | Heavy-duty, power tools |
| 10-Gauge | Up to 30 amps | Extra heavy-duty, industrial uses |
Factors to Consider
- Device Power Requirements: Match the cord’s gauge to the amperage of the device.
- Cord Length: Longer cords require lower gauge to prevent voltage drop.
- Environment: Outdoor or rugged use may require additional durability features.
Example Use Case
For powering a 15-amp circular saw, a 12-gauge extension cord is ideal. If the cord exceeds 50 feet, a 10-gauge is recommended.
Can I plug my AC into a heavy-duty extension cord?
Air conditioners are high-power devices. Is it safe to use a heavy-duty extension cord for them?
Yes, you can plug an AC into a heavy-duty extension cord, but the cord must be rated for the AC’s power requirements.
Using the wrong cord can lead to overheating or insufficient power delivery.

Requirements for AC-Compatible Extension Cords
- Gauge: A 12-gauge or thicker cord is recommended.
- Amperage Rating: Ensure the cord supports at least 15 amps.
- Length: Keep the cord as short as possible to prevent voltage drops.
Risks of Using Inappropriate Cords
- Overheating: Thin cords can overheat and pose a fire hazard.
- Device Damage: Insufficient power can harm the AC’s motor.
- Energy Loss: Thin or long cords can reduce efficiency.
Recommended Heavy-Duty Cords for ACs
| Brand | Gauge | Length | Special Features |
|---|---|---|---|
| Southwire | 12 | 25 ft | Flexible and abrasion-resistant |
| Iron Forge | 10 | 50 ft | Rugged and weatherproof |
| AmazonBasics | 12 | 15 ft | Compact and easy to store |
Which is better, a 16 or 14 gauge extension cord?
The choice between 16- and 14-gauge cords depends on the application. Which one is better?
A 14-gauge extension cord is better for moderate power needs, while a 16-gauge cord is suitable for light-duty applications.
The thicker 14-gauge wire can handle higher currents safely.

Key Differences
- Wire Thickness: 14-gauge wires are thicker, supporting more current.
- Power Capacity: 14-gauge cords can handle up to 15 amps, while 16-gauge is limited to 13 amps.
- Application: 16-gauge is for indoor use, while 14-gauge can handle outdoor tools.
Example Applications
| Application | Recommended Gauge |
|---|---|
| Table Lamp | 16-Gauge |
| Electric Fan | 16-Gauge |
| Leaf Blower (small) | 14-Gauge |
| Circular Saw | 14-Gauge |
Safety Tip
Always choose a cord with a gauge rating that exceeds the power demand of your device for added safety and durability.
How many amps can a 25-foot 12-gauge extension cord handle?
Extension cord length affects its capacity. So, how many amps can a 25-foot 12-gauge extension cord handle?
A 25-foot 12-gauge extension cord can handle up to 20 amps safely.
Shorter lengths minimize voltage drops, allowing the cord to carry more current efficiently.

Relationship Between Gauge, Length, and Amperage
- 12-Gauge Cord at 25 ft: Supports 20 amps, ideal for most heavy-duty tools.
- Longer Cords: For 50-100 feet, the capacity decreases due to resistance.
- Voltage Drop: Keep the cord as short as possible for high-power devices.
Example Scenarios
| Device | Amps Required | Suitable Cord |
|---|---|---|
| Power Drill | 8-10 amps | 12-gauge, 25 feet |
| Portable Heater | 15 amps | 12-gauge, 25 feet |
| Large Air Compressor | 18-20 amps | 12-gauge, 25 feet or less |
Voltage Drop and Efficiency
For a 12-gauge cord:
- A 25-foot cord has minimal voltage drop, maintaining efficiency.
- At 50 feet or more, consider a 10-gauge cord for similar performance.
Conclusion
Understanding the differences between light-duty and heavy-duty cords is crucial for safe and efficient power delivery. By selecting the correct gauge, length, and cord type for your devices, you can ensure reliability and avoid potential hazards.
