Using a Standard Method of Measurement for Cords Depending on the application, cable length in a power cord or cord set is a choice for the designer. Interpower offers standard length power cords and cord sets, as well as specialized lengths. When measuring all power cords and cord sets, Interpower uses a standard method of measurement.

A common practice for cord set manufacturers is the option to be able to change cable suppliers. This can be done as a safety net to limit shutdowns and as a price controlling measure. It also means that with manufacturers having multiple-approved cable suppliers, customers should not expect that all markings found on the cable are included in their company-specific specifications.

A ferrule is an internal component that can be used for better electrical connection in applications where the spread of bare strands could cause a problem.

A switch is an electrical component on a piece of equipment that may be used when incoming power needs to be controlled. From being used on a vacuum cleaner to a life-support machine, the purpose of a switch is to open and close a circuit. Opening a circuit (turns a device OFF) is achieved by breaking a connection in the circuit. This stops current flow. Closing the circuit (turns a device ON) allows the current to flow again.

When designing a new electrical or electronic equipment product, an important factor to determine is circuit protection. The main function is to provide protection to both the equipment and the equipment operator in the event of a circuit overload.
