Frequently asked questions — Extension cords
What is the difference between an indoor and outdoor extension cord?
Outdoor extension cords, like the DEWENWILS 25 ft. 14AWG SJTW ($29.99) or Monster 12/3 SJTW ($139.99), are designed with more durable insulation (e.g., SJTW) to withstand moisture, temperature changes, and UV exposure. Indoor cords, such as the HDX 6 ft. 16/2 Light Duty ($2.87), are lighter duty and not suited for outdoor elements, posing a safety risk if used improperly outside.
What wire gauge (AWG) do I need for my tools?
For light-duty applications like lamps or small electronics, a 16 AWG cord (e.g., HDX 6 ft. 16/2 at $2.87) is typically sufficient. For medium to heavy-duty tools like lawnmowers or power saws, you'll need a thicker 14 AWG or 12 AWG cord (e.g., DEWENWILS 25 ft. 14AWG at $29.99 or Monster 12/3 SJTW at $139.99) to prevent overheating and voltage drop, which can damage tools and pose fire hazards.
How many outlets should my extension cord have?
The number of outlets depends on how many devices you need to power. Many basic cords, like the Hyper Tough 16AWG 2 Prong ($2.97), have a single outlet. For multiple devices, consider options like the DEWENWILS 25 ft. 14AWG SJTW with 6 outlets ($29.99) or the Vebreda 50 ft. 14/3 Outdoor Power Stake with 6 Outlets ($65.99). Ensure the total wattage of all connected devices does not exceed the cord's capacity.
Are grounded (3-prong) extension cords safer?
Yes, grounded (3-prong) extension cords are generally safer for appliances and tools that require a ground connection. Products like the GE 1-Outlet Indoor/Outdoor Grounded Workshop Extension Cord ($12.99) or the Project Source 100-ft 16 / 3 Light Duty 3 Prong ($19.48) offer an extra safety measure by providing a path for excess electricity to dissipate, preventing electric shock in case of a fault.
What is the best extension cord for heavy-duty outdoor use?
For heavy-duty outdoor tasks, the Monster Extension Cord Just Power It Up Outdoor Yellow 12/3 SJTW ($139.99) or the Ace Outdoor Extension Cord 12/3 SJTW ($79.99) are top choices. Their 12-gauge wire is suitable for high-power tools, and the SJTW rating indicates superior durability and weather resistance for construction sites or demanding landscaping projects.
How long of an extension cord do I need?
Measure the distance from your power outlet to where you'll be using the device, then add a little extra for flexibility. For short distances, a 6 ft cord like the HDX 6 ft. 16/2 ($2.87) is adequate. For larger areas, consider 25 ft options like the DEWENWILS 25 ft. 14AWG SJTW ($29.99) or even 100 ft cords like the Project Source 100-ft 16 / 3 Light Duty ($19.48).
