How To Tell What Gauge An Extension Cord Is

Gauge is typically listed along with the number of conducting wires in the cord. For example, a 14/3 cord contains 14-gauge wire and has three conductions inside. Extension cord lengths determine the cord’s power capacity. Every extra foot of cord increases the electrical resistance.

Which is better 12 gauge or 14 gauge extension cord?

For 100 feet, the 14 gauge cord works for 11-13 Amps, while the 12 gauge cord is best suited for 14-15 amps. If your cord is 150 feet long, the 14 gauge is best suited for 1-7 Amps, whereas the 12 gauge will support 8-10 Amps. This shows that the extension cord’s length also plays a part in the power it helps safely.

Which is better 10 gauge or 12 gauge extension cord?

Round down = 10 Gauge. Most devices will do fine with 12 gauge extension cords. Power hungry devices such as lawnmowers, heavy machines, require a lower gauge such as 10AWG. Keep in mind, the lower the gauge means the thicker the cord.

What gauge is a 3 prong extension cord?

Houseables’ 3-prong 10-gauge/3-conductor heavy-duty extension cord measures 25-feet in length. It gives you an all-weather power cord that is both flexible and able to run for an extended period without overheating or shorting out.

Can a 12 gauge extension cord handle 20 amps?

14 Gauge for 11-13 Amps. 12 Gauge for 14-15 Amps. 10 Gauge for 16-20 Amps.

How far can you run 12 gauge extension cord?

12-Gauge Cords: If your tool load is between 10 and 15 amps and the length of the cord is 50 to 100 feet, you need a 12-gauge cord to safely power any tool. This is a great extension cord for many purposes.

Can 12 gauge wire handle 30 amps?

You should not use a 30-amp circuit breaker on a 12-gauge wire. The circuit breaker installed on a circuit is of a specific size to protect a certain wire gauge. This higher current can damage the thinner wire, melt the insulation, cause short circuits, fire, and even lethal shock.

What does 12 AWG mean on an extension cord?

12 gauge=heavy duty. 10 gauge=very heavy duty. The longer the extension cord, the bigger the drop in amps. It’s important to use a cord which is a heavy enough gauge for the tool or appliance.

What is the most heavy duty extension cord?

Best overall: Coleman 14 Gauge 100 Ft. Extension Cord. Best with a power strip: Anker Power Strip Extension Cord. Best heavy-duty extension cord: Watt’s Wire 14-Gauge Extension Cord.

Is a 14-gauge extension cord heavy duty?

Frequent use cords. A 14-gauge cord is for medium or frequent duty applications (lawnmowers, power drills, table saws, television sets, etc.). These cords are also great for things like power tools, electric chainsaws, leaf or snow blowers, etc. They can handle larger tools and equipment and heavier use.

Which is better 12 or 16-gauge extension cord?

Within 50 feet of your outlet, use a 16-gauge light-duty cord for blowers. For a higher Amp or a greater distance from the outlet, go with a 14-gauge medium-duty cord. Look for a “W” on the jacket if the cord is rated for outdoor use.

How can I tell if an extension cord is for outdoor use?

Letter Designation On the extension cord packaging or on the cord itself, the letter “W” indicates that the cord is designed for use outside. Outdoor extension cords have a heavy-duty appearance and tend to have tough, bright orange covers that are made from rubber, vinyl or plastic.

Can you connect a 14 gauge extension cord to a 12 gauge extension cord?

A 14 ga cord has more resistance than 12 ga so putting them together increases the resistance to about 2.5X so that’s bad. THere’s no way you can make the resistance per foot lower by chaining cords together. No.

How far can you run 12 gauge wire on a 20 amp circuit?

You can run a 12 gauge wire up to 70 feet on a 15 amp circuit. That number drops to 50 feet if you run 12 gauge wire on a 20 amp circuit.

How much wattage can a 12 gauge extension cord handle?

Matching Extension Cord to Load Extension Cord Wire Gauges, Amperage Rating, and Wattage #18 5 Amps 600 Watts #16 7 Amps 840 Watts #14 12 Amps 1,440 Watts #12 16 Amps 1,920 Watts.

Is a 200 foot extension cord safe?

Another important and easy to spot violation to look for is when users plug one extension cord into another one. This is a violation of the OSHA standards because it can potentially lead to a fire, equipment failure, or electrocution. In general, extension cords should not exceed 100 feet in length.

What is the difference between 14 gauge and 16 gauge extension cord?

Within 50 feet of your outlet, use a 16-gauge light-duty cord for blowers. For a higher Amp or a greater distance from the outlet, go with a 14-gauge medium-duty cord. Look for a “W” on the jacket if the cord is rated for outdoor use.

How many amps can a 100 foot extension cord handle?

We also allowed for up to a 5% voltage drop—which some people might consider too high. With that being the case, only one of our recommendations hit that level, the 100-foot 12-gauge extension cord with a full 15A draw.

Can wire gauge be too big?

If a wire gauge is “too big” then it is a lot more expensive and is harder to bend, as well as more difficult to attach with wire nuts or to switches. Other than that, not much of anything.

What gauge wire is 12 3?

The designation 12/2 indicates AWG 12 wire with two conductors (AC hot and AC neutral), 12/3 indicates AWG 12 wire with three conductors (two AC hot and AC neutral). Both designations also typically include a smaller bare copper earth ground conductor.

What do the different gauges of extension cords mean?

The lower the number, the bigger the gauge and the greater the amperage and wattage is. In addition, a cord with a larger gauge will carry power a greater distance without dropping as much voltage compared to a cord with a smaller gauge. Voltage drops over distance, so to offset this, choose a cord with a larger gauge.
