Frequently Asked Questions on 12/3 Extension Cord 100 Ft
How many amps can a 100 ft 12 gauge extension cord handle?
A 100 ft 12 gauge extension cord is rated for 15 amps maximum load at 125 volts. This rating accounts for voltage drop over the 100-foot length while maintaining safe operating temperatures.
For optimal performance and tool operation, it's recommended to stay within 80% of the maximum rating, or about 12 amps for continuous use.
Can a 12 3 extension cord handle 20 amps?
While 12 gauge wire can technically handle 20 amps at very short distances, it's not recommended for 100-foot lengths due to significant voltage drop.
At 100 feet, a 12/3 extension cord should be limited to 15 amps to ensure safe and efficient power delivery. If you need to pull 20 amps over long distances, you should upgrade to a 10 gauge or larger cord.
How far can you run 12 gauge extension cord?
A 12 gauge extension cord can be safely run up to 100 feet while maintaining its full 15-amp rating and ensuring proper voltage at the equipment end. For distances beyond 100 feet, voltage drop becomes a significant concern that can affect tool performance and safety.
To maintain optimal power delivery over longer distances, either step up to a larger gauge or reduce the amperage load on the circuit.
What gauge should a 100 ft extension cord be?
For a 100 ft extension cord, 12 gauge is the standard recommendation for most power tools and equipment drawing up to 15 amps. This gauge provides the optimal balance between power handling capability and cord flexibility for everyday use.
If you're regularly powering multiple tools or equipment near the maximum rating, a 10 gauge cord offers additional capacity and better voltage maintenance over the distance.
