Those covers make it harder for an inquisitive child or clumsy adult to stick something in the outlet and shock themselves, making the Cordinate option considerably safer.
A power cord or appliance coupler may have a retaining clamp, a mechanical device that prevents it from inadvertently being pulled or shaken loose. Typical application areas with stricter safety requirements include medical technology , stage and lighting technology, and computing equipment. For specialty equipment such as construction machinery, sound and lighting equipment, emergency medical defibrillators and electrical power tools, used in locations without a convenient power source, extension cords are used to carry the electric current up to hundreds of feet away from an outlet.
In North America, the National Electrical Manufacturers Association develops standards for electrical plugs and receptacles and cables. International power cords and plug adapters are used in conjunction with electrical appliances in countries different from those in which they were designed to operate. Besides a cord with one end compatible to receptacles or a device from one country and the other end compatible with receptacles or devices from another country, a voltage converter is usually necessary, as well, to protect travelers' electronic devices, such as laptops, from the differing voltages between the United States and places like Europe or Africa.
North American lamp cords have two single-insulated conductors designed for low-current applications. The insulator covering one of the conductors is ribbed parallel to wire for the entire length of the cord, while the other conductor's insulator is smooth. The smooth one is hot and the ribbed one is neutral. IEC power cables come in normal and high-temperature variants, as well as various rated currents. The connectors have slightly different shapes to ensure that it is not possible to substitute a cable with a lower temperature or current rating, but that it is possible to use an overrated cable.
Cords also have different types of exterior jackets available to accommodate environmental variables such as moisture, temperature, oils, sunlight, flexibility, and heavy wear. For example, a heating appliance may come with a cord designed to withstand accidental contact with heated surfaces. Worldwide, more than a dozen different types of AC power plugs and sockets are used for fixed building wiring. Products sold in many different markets can use a standardized IEC connector and then use a detachable power cord to match the local electrical outlets.
After our top pick, it was the second-most-flexible gauge cord we tried. The outlet on the end takes a firm grasp of any power cords you plug into it, reducing accidental disconnections. Unlike many inexpensive, indoor cords, this one has a third prong for grounding, which provides extra protection against electrical shorts and shocks.
All of the picks in this guide are available primarily from online retailers; the best extension cords are rarely available on the shelf at big-box hardware stores. But if you need a cord right now, we do have tips for choosing the best extension cord at your local hardware store. In addition to heavy-duty and outdoor cords, we also considered indoor extension cords for all the other light-duty uses that come up in everyday life. Just like with their beefier siblings, these cords may seem similar on the shelf, but small differences can make for a safer cord that looks better when you need it to charge your phone on your power-starved nightstand or plug in a lamp on the wall without an outlet in your living room.
That rating matches most residential breakers and many older fuses which are designed to cut power if you try to draw more than 15 A and will prevent someone from accidentally overloading household wiring or extension cords. How much power a cord can carry is related to how thick the wires are inside and the length of the cord. The longer an extension cord, the thicker the conductive copper wires inside need to be. Wire gauges are often marked in AWG, where smaller numbers signify thicker wires.
If you use cords that are too thin for the length and power you that you need, you can run into two problems. The most common problem is voltage dropping from the outlet to the far end of the cord. In the US, residential power is nominally volts, but this sags by the time you get to the end of a too-long, too-thin cord.
Pulling too much power through an undersized cord will cause it to heat up, eventually melting the jacket of the cord and exposing the bare wiring underneath. Even if all three of those things were plugged in, they would be unlikely to use more than 7 A. The more flexible the better. We could highlight the safety advantage of flexible cords—models that lay flat when stretched out are less likely to snag or trip someone walking over them.
But the real reason we think that the most flexible cords are the best is because they reduce frustration. Plus, more flexible cords are easier to coil and store correctly, which should extend their useful life.
All of the cords we tried were reasonably flexible at room temperatures, so we decided to test them in more challenging conditions. Facilities manager Frank Plant arranged for us to store six of the most promising foot cords in one of the coldest corners of the facility for two days.
Small differences in the outlet on an extension cord can set the best ones apart from the mediocre. The longer the strain relief—the little plastic turtleneck that runs up the cord—the better the wires will resist pulling out the back of the receptacle from repeated bending at tight angles. We plugged multiple power cords into each outlet to see how smoothly and firmly they connected, and noted which ones felt like they could hold up to repeated use.
We also compared the strain relief on each cord, and bent the necks at back and forth to make sure the cord stayed put. We like extension cords that have a see-through outlet and include a small LED light to let you know when the cord is plugged in and powered.
For indoor cords, we recommend flatter plugs that sit flush to the outlet. That helps prevent the plug from getting pulled out—or worse, partially pulled out—when you move a chair or a pet bumps into it. If you buy only one extension cord, get the U. It has thick gauge wires inside that can handle up to 15 A of electricity, but was still by far the most flexible cord of any we tried.
Like all of the cords we tested, the U. Extreme All-Weather Extension Cord can handle 15 A, making it hardy enough to handle any tools or equipment powered by a standard household plug. The gauge wire inside is thick enough to deliver the proper voltage from end to end, and the coating on the entire length of the cord a jacket made of a rubbery elastomer instead of a plasticky vinyl is not only weather resistant, but also oil resistant.
