The National Electrical Code (NEC) is an American standards body which defines a set of standards for certain types of cabling and how they should be installed and used.
NEC types are acronyms consisting of a prefix describing cable type (e.g. coax, CATV, fiber optic) and a suffix indicating the type of flame test it has passed and where it can be installed.
Computer cable can also be called “Security” or “Alarm” cable.
Underwriters Laboratories categorises some computer cable as appliance wiring material (AWM). It has become an industry standard. There are 5 different style numbers.
AWM cable is designed for the internal wiring of factory-assembled, “listed” appliances such as computers, whitewear, and industrial equipment.
UL2464 is a loose standard defining some of the properties of computer cable, maintained by Underwriters Laboratories.
