Interpower Power Cords and Cord Sets
All electrical equipment needs some way of receiving power and most designers use some type of power cord or cord set. Interpower manufactures and sells power cords, cord sets, jumper cords, and connector power cords.
A power cord consists of cable with a plug (molded or hand wired) on one end and exposed conductor wires, terminated conductors (such as ring terminals or QDs), or blunt/flush cut conductors on the other end. A power cord is used to connect the equipment directly to the power mains.
- A power cord is normally hard-wired in the equipment by the manufacturer, thus ensuring proper use of the equipment. Replacement of a power cord requires access inside the equipment.
Jumper Power Cord (or Accessory Power Cord)
A jumper power cord is made from cable and an IEC 60320 Sheet E or Sheet I plug connector (molded or hand wired) on one end. A jumper power cord is used to connect a secondary piece of equipment (accessory) to a primary piece of equipment which is supplying the power to the peripherals.
- Jumper power cords are used in applications where the power source connection is an IEC 60320 outlet device, found on a primary piece of equipment. The IEC 60320 plug connector can make the connection for power.
- A jumper power cord application would include multiple pieces of equipment working together to accomplish one task. The jumper power cord extends from the power source to the accessory equipment.
Connector Power Cord
A connector power cord has an IEC 60320 or country-specific connector (molded or hand-wired) on one end of the cable with the opposite end being exposed conductor wires, terminated conductors, or blunt/flush conductors.
- Connector power cords are used in specialized applications. They are designed to provide electrical power to peripheral equipment. The unterminated end can be wired into the equipment with the connector providing electrical power to accessory equipment.
A cord set consists of cable with a country-specific plug (molded or hand wired) on one end and an IEC 60320 connector or country-specific connector (molded or hand wired) on the other end. It is meant for connecting equipment directly to the mains supply.
- Cord sets enable OEMs (original equipment manufacturers) to design equipment to be shipped anywhere in the world by changing only the cord set.
- Installation of a cord set takes less labor than installation of a power cord.
- It is easier to replace a damaged cord set than a hard-wired power cord.
Jumper Cord Set (or Accessory Cord Set)
A jumper cord set works like a jumper power cord. The difference is a connection device on both ends of the cable instead of just the plug end. A jumper cord set includes an IEC 60320 plug connector and an IEC 60320 connector and transfers power from a primary piece of equipment to an accessory or peripheral piece of equipment.
- Jumper cord sets are designed for specific applications.
- They are used to “jump” power from unit to unit within one application. These cords are different in that they are able to plug into each other. Examples: computer monitor, computer CPU, computer printer.
Choosing a Power Cord or Cord Set
Selection of the appropriate power cord or cord set for each export market is an important step for equipment designers to ensure the product can be easily used by their North American and international customers. Choosing a cord usually involves four steps:
- Identify the correct plug for the country of export
- Determine the rating of the power cord or cord set
- Choose the correct cable
- Choose the correct connector, if utilizing a cord set
Interpower follows these guidelines when manufacturing power cords and cord sets:
- North American and international standards are followed
- Minimum and maximum lengths are followed per country regulations and/or standards
- Current ratings are based on the lowest rated component
- Voltage ratings are based on the lowest rated component
- For cord set configuration combinations that are allowed—see International Cord Set Configurations chart and North American Cord Set Configurations chart
To determine cord specifications per a specific country or region, see North American Power Cords and Cord Sets and International Power Cords and Cord Sets, along with More Information on Cords. See also more information on the IEC 60320 products.
To determine which plug patterns are used in specific countries, see Guide to Worldwide Plug/Socket Patterns and Power Mains.
If the power system components need to be labeled, packaged, or kitted in a specific way, or a cord needs to be a custom length, there are several options offered by Interpower.
- Labels—Wrap, Flat, Flag, Warning
- Packing—Bundle (standard packaging), Hank, Coil, Bag, Box, Kit
- Custom cord lengths—Standard length (2.5m/8.2’), Custom lengths (begin as short as 1’)
- Outer jacket and insulated conductor custom strip lengths—Standard strip length on outer jacket (50mm), Standard strip length on insulated conductor jacket (10mm); 1-week U.S. manufacturing lead-time for custom strip lengths
- Terminations—Ring terminals, quick disconnects (QD), spade terminals (insulated or un-insulated), ferrules (double or single-action which can be insulated or un-insulated), ultrasonic welding or tinning of individual conductors
Interpower manufactures and sells power cords and cord sets for a number of different countries and regions. Power cords and cord sets manufactured by Interpower are 100% tested.
