16/3 Extension 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.
What are the lengths of extension cords?
Recommended wire gauge for extension cords Cord length What thickness you need 25 feet 14/3 (14 AWG) 50 feet 12/3 (12 AWG) 100 feet 10/3 (10 AWG).
How short do extension cords come?
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.
Does length of extension cord matter?
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.
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 is the difference between 12 gauge and 14 gauge extension cords?
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.
What is the minimum size of the electrical extension?
A #14 gauge extension cord is minimum and #12 gauge is preferred.
What is an 18 gauge extension cord?
Gauge is a numerical rating of copper wire diameter and is identified by an American Wire Gauge (AWG) number. For this reason, long extension cords have a lower capacity than shorter cords of the same AWG size. For example, an 18 AWG cord may only be rated for 5 to 7 amperes (amps) of load at a length of up to 25 feet.
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.
What is a 14-gauge extension cord good for?
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.
What is AWG in wire size?
AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors. The American Wire Gauge chart is based on the number of dies originally required to draw the copper down to the required dimensional size. It means the higher the AWG number is, the smaller the wire diameter is.
What is a 16-gauge extension cord good for?
Sixteen-gauge cords are low wattage and are intended for use with small appliances such as portable fans, alarm clocks, table lamps, or floor lamps (note: an electronic device such as a TV or computer should be connected to a surge protector).
What happens if cable is too small?
Too-Small Wire Can Get Hot Your circuit breaker should trip and stop the flow of electricity through the circuit. The breaker disrupts electrical flow to protect the affected wire.
How long can a 12 gauge extension cord be?
The essential extension cord A 12 gauge extension cord rated at 20 amps is a versatile extension for both indoor and outdoor use. Over 100-feet, it can safely handle 16 amps. It lets you run a single high-wattage power tool or two to three smaller tools or appliances.
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 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.
What’s the longest extension cord?
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.
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.
