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.
Do you lose power with long extension cords?
Long extension cords can cause significant drops in voltage to appliances. Anything that resists the flow of electricity causes voltage to drop.Whether an extension cord causes a noticeable or significant voltage drop depends on the length and gauge of the wire and the appliance plugged into it.
Does a long extension cord use more electricity?
There are two factors: cord length and thickness. The thicker the copper wire, the more electricity it can carry. However, because transmitted power diminishes over distance, longer extension cords require heavier wire to deliver the full current rating required by an appliance.
Does length of extension cord matter?
Extension cord length is an incredibly important factor. The longer the extension cord is, the more resistance. 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.
Is it bad to use a long extension cord?
With continuous use over time, an extension cord can rapidly deteriorate, creating a potentially dangerous electric shock or fire hazard.Do not overload extension cords or allow them to run through water or snow on the ground. Do not substitute extension cords for permanent wiring.
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.
What should not be plugged into an extension cord?
Rule two: never plug high power capacity appliances, like space heaters, refrigerators, or microwave and toaster ovens into power strips or extension cords. These appliances have higher power capacity and need to be plugged into a wall outlet directly.
How much electricity does a extension cord use?
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.
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.
Whats the longest extension cord you can use?
Yard Master 9940010 120-Foot Outdoor Garden Extension Cord, Lime Green. 120-foot outdoor extension cord is super flexible and light weight, for less tangles when using. A 16/2 cord means the wire thickness is 16-gauge, and each plug has 2-prongs.
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. On the other hand, a copper wire of the same AWG has a rating of 25 at 140°F, 25 at 167°F, and 30 at 194°F.
How much power can a 12 gauge extension cord handle?
14-15 Amps
12 Gauge for 14-15 Amps.
How far can you run 12 gauge wire on a 20 amp circuit?
Originally Answered: How far can you run 12 gauge wire on a 20 amp circuit? About 400 feet. After that voltage drop is a factor and the gauge will have to be increased or the voltage increased.
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.
Can you plug in an extension cord into a power strip?
DON’T daisy chain power strips and extension cordsjust don’t.Only plug in an extension cord into a power strip if the power strip has been hard-wired into the electrical system. Otherwise, avoid plugging an extension cord into a power strip. Only plug power strips directly into a wall outlet.
Can you use an extension cord with a power recliner?
Do not use an extension cord, adapter, or surge protector. The power feature is operated by a power switch, located on the side of the recliner. Before moving the recliner, disconnect the electrical plug from the wall outlet and secure the mechanism to prevent unexpected opening.
What are the disadvantages of extension wires?
Extension cords can overheat and cause fires when used improperly. Overheating is usually caused by overloading or connecting appliances that consume more watts than the cord can handle. Damaged extension cords can also cause fires. Extension cords should only be used temporarily.
What gauge extension cord do I need for power tools?
14-Gauge Cords: Any 14-gauge cord between 0 and 50 feet long will adequately handle loads between 10 and 15 amps. 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.
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.
Is a 13 amp extension cord enough?
Look for cords that can handle 15 amps
We recommend skipping indoor/outdoor extension cords rated for 10 A or 13 A. Instead, get one rated for at least 15 A. (If the cord doesn’t list a maximum amperage, you should skip it entirely.)
Is a 200 foot extension cord safe?
Power cord ratings are determined by length. If you plug two identical cords into each other, that reduces their current capacity in half and can possibly result in voltage drop and overheating. In general, extension cords should not exceed 100 feet in length.
