Power cords can be called a variety of things, from mains cables to extension cords. They connect appliances to the main electrical system by plugging one end into a wall socket, extension board, or appliance receptacle. Power cords can be used to power appliances that require an outlet, as well as to recharge battery-powered equipment. They carry either direct current or alternating current. Power cords can vary in length and voltage, so it’s important to select the right one for the type of equipment you’re using.
A power cord is made of three parts: the connector, the wire used for grounding, and the insulation. The two types of cords are used for different applications, including information technology equipment, consumer products, and outdoor use. The connectors used in a cord are typically marked with a code standard (called “C”) and have different standards and regulations. The most common connectors used worldwide are C13, C14, and C19.
The plug and receptacle of a power cord must meet UL 498 and CAN/CSA C22.2 no 42. The conductor size of a cord is rated in AWG (American wire gauge) and millimeters. In North America, power cords for ITE are rated by UL or CSA. They also carry an NRTL (National Electrical Manufacturers Association) certification mark. In addition to the international standard, the U.S. standard UL 817 is also used in the U.S.
NEMA standards are generally accepted in most countries in North America. The most common power cords in the U.S. are l1430 NEMA 5-15P to NEMA 5-15R, but there are also different types. The NEMA 5-15P to C13 and C15 are two common types. These are the most common power cords. You may find an extension cord for a plug from an NEMA 5-15P to C15 power cord.
The wire that makes up a power cord is a conductive wire called copper. Insulative material used in cord sets includes silicone or vinyl thermoplastic. FT2 and “O” cords are flame-retardant. PVC-coated cords are heavy-duty and resistant to heat and withstand various temperature conditions. And they come in many different sizes and insulations. If you need a cord for a particular appliance, you should consult your manufacturer for the appropriate cord.
Plug patterns vary from country to country. For help determining the correct plug pattern, consult Interpower’s Guide to Worldwide Plug Patterns. Japanese and North American Class I cords have similar appearances, but the latter do not bear the Japanese approval symbol. Hence, you should check the cords before you buy them. They may not come with a safety warning label, so you should always check for this. You can also contact Interpower for free technical support.
A standard power cord set comprises a flexible cord with male and female connectors on either end. The male connector connects to a wall outlet, while the female plug attaches to electrical equipment. These couplers are designed to prevent accidental connection. They can also detach from the power supply and connect the equipment. They have a male and female plug and are attached to one another. If you’re using multiple devices, you’ll need multiple cords to plug everything into one outlet.
