Yard Master Outdoor Extension Cord Measuring 120 feet, it’s the longest cord on this list and can stretch pretty much wherever you need. The 16-gauge wire carries plenty of power—125 volts, to be exact—while the durable weatherproof jacket protects against moisture and sunlight.
What is the maximum length of an extension cord?
In general, extension cords should not exceed 100 feet in length. However, by plugging one extension cord into another, the maximum cord length can be easily exceeded. If the job requires more than a 100-foot distance, a temporary power distribution box is required.
What lengths do extension cords come in?
Extension cords come in various lengths, from a few feet to 100 feet. Although copper wire is a very good conductor, it does have an amount of resistance that generates heat. This heat can potentially damage the extension cord as well as the devices and appliances that are connected to it.
What is the longest heavy duty extension cord you can buy?
Medium-duty cords can range from 25 to 150 feet, with a 14 to 15 amp power rating and 14-gauge wire. They are useful for powering lawn mowers and power drills. Heavy-duty cords can range from 25 to 150 feet, with a 16 to 20 amp power rating and 10- or 12-gauge wire.
Does the length of an extension cord affect the power?
As the cord gets longer, the current carrying capacity of the cord gets lower. For example, a 16 gauge extension cord less than 50 feet in length can power a 1625 watt (W) appliance. A 16 gauge cord that is longer than 50 feet in length can only power an appliance up to 1250W.
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 a 12 gauge extension cord handle 20 amps?
12-Gauge. A 12-gauge aluminum extension cord has a rating of 20 amps at 167°F and 25 at 194°F. A copper wire of the same AWG has a rating of 25 at 140°F, 25 at 167°F, and 30 at 194°F.
What happens if an extension cord is too long?
An improperly sized extension cord can cause a tool or appliance motor to burn out if allowed to run for too long. It can also cause a dangerous situation if it overheats. There are two factors: cord length and thickness. The thicker the copper wire, the more electricity it can carry.
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.
Is a shorter extension cord better?
Every extra foot of cord increases the electrical resistance. This decreases the power the cord can deliver to connected devices. For best results, use the shortest extension cord possible. Tip: If you’re replacing an old cord, look for the AWG number printed on the jacket to select a new cord with the same gauge.
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.
How do I make a 20 amp extension cord?
Cut three equal lengths of wire. Strip 1/2 inch of insulation from each wire end. Attach one end of the first wire to the “hot” plug connector on the male plug, and solder the connection. Attach the other end of the first wire to the “hot” plug connector on the female plug, then solder that connection.
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.
What gauge extension cord is best?
Larger numbers mean smaller wires, which in turn means it can carry less power. A cord measuring 14 AWG is the thinnest we recommend—and at lengths of only 25 feet or shorter—and the much thicker 10 AWG is likely the thickest gauge you’ll find in an extension cord.
Which is better 14 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 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 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.
