1.1 These requirements cover single and multipole connectors, intended for factory assembly to copper or copper alloy conductors or printed wiring boards, for use in data, signal, control and power applications within and between electrical equipment.<\/p>\n<\/p>\n

\n

1.2 These requirements apply to devices categorized as follows (See ). Type designations used in this Standard only serve as a guide to determine appropriate requirements, and do not represent an assigned rating. A device without an assigned current rating is considered to be either a Type 0 or Type 1A or Type 5 depending upon the assigned voltage rating.<\/p>\n
