Proper positioning of the power cord plug is critical to your safety. If you're not sure which direction to face, you can refer to the jack or the product case. If you choose the latter, be sure to secure the plug under the hook on the case. The plug can be secured with a lock cord or twist lock feature. Power cords may also have accessories such as fuses and leakage detectors for overcurrent protection.

There are several types of plugs. Some plugs are polarized and some are not. A polarized plug has a wider neutral pin than a fire pin. This enables the plug to fit into a polarized outlet. Non-polarized plugs, on the other hand, have equal-width prongs. Some sockets do not have tabs or pins that you can push in.

The International Electrotechnical Commission (IEC) has put together a guide to plugs. However, the guidance does not take into account all possible changes. These plugs may have different names, sizes and functions. For example, a CEE 7/7 power socket, while technically not a plug, has a fancy name and is intended for use in Europe. While the most powerful outlet in the world may be the Type N power cord, it may not work in the US. However, you will be able to use most Japanese plugs in North America.

The plug may have some additional features, such as a fuse, a ground pin, or a ground sleeve. For example, a plug with a grounded sleeve helps prevent water damage to the device. Lights to indicate voltage may be included with the power cord set. Likewise, power cords rated over 10A may have insulating sleeves. Some of these characteristics may also be seen on power lines rated at 15A.

The plug and socket can also be combined into one, either fixed or detachable. A single cord can be anywhere from 6.6 feet to 32.8 feet in length, but can be as short as two feet. Some plugs feature locking cords or twist locks to prevent tension from being transferred to the plug. These features are also found on power cord sets for sensitive electronics. Power cord plugs may also have fluorescent lights to indicate voltage, leakage detectors, and other features designed for safety.

The most important thing about plugs is that the best plug is the one that fits your outlet. To find the right one, read the manufacturer's instructions carefully. The plug may also have an insulating or grounding sleeve that helps prevent water from entering the circuit. The sleeve is particularly useful in situations where a liquid contact device may be placed in a receptacle. It also prevents accidental contact of the pins when the plug is partially inserted into the socket.
