Power cords are essential for powering appliances and devices. Various types of power cords exist to suit a variety of applications. The cords themselves are classified by their gauge ratings. The AWG (American Wire Gauge) rating refers to the thickness of the wires. The lower the number, the thicker the wires are. Typically, the longer a power cord is, the greater the voltage drop and capacity of the device. A shorter cable, on the other hand, maintains the same power level from the outlet to the other end.
A power cord has three components: an electrical connector, a ground wire, and a plug. It acts as a universal conduit to transmit electricity from a power outlet to a device or appliance. Power cords are subject to numerous international standards, regulations, and markings. To prevent any electrical hazards, power cords must meet a certain voltage and wire gauge. These are all important factors to consider when choosing a power cord.
Most computer desktops utilize a c13 power cord. The IEC 60320 standard specifies the electrical requirements for this type of power cord. It also specifies the different types of plugs used by different countries. In addition to the voltage and current of different types of cords, the connectors also differ in shape and size. The following are some common types of power cords:
An extension cord (also known as a power extender) is used Streamer Lights to provide power to equipment in remote or unreliable locations. Its ideally long cable features a power plug at one end and a socket on the other. Extension cords are compatible with multiple power outlets and are a great solution for small workspaces. They also allow for the use of different appliances. To avoid electrical hazards, choose an extension cord that meets these standards.
While many types of power cords are suitable for use in temperature-controlled and dry indoor environments, a few special types are recommended for wet environments. For example, power cords for medical equipment need to be waterproof. These types should feature a plug with a sealed socket to keep water out. Additionally, brightly colored power cords reduce the risk of tripping hazard. Some cords even include a surge protector.
A power cord can be detachable from an appliance. If it is detachable, it is recommended to use a plug cover to keep children from sticking objects into the socket. The cord may have twist-lock features and other attachments. Cord sets often contain accessories such as fuses for overcurrent protection, pilot lamps to indicate voltage, a leakage current detector, and more. Further, the power cord should meet the safety and electrical standards for the particular appliance.
In addition to the plug, a power cord can also be labelled by its country of origin. In North America, the plug and receptacle are regulated by the UL 62/CSA C22-2 No 49-14 standard. The cordage, meanwhile, should meet the requirements for the IEC 60779 connector standard. Some countries have specific plug and socket patterns, so it is important to check the certification of the cord.
