UL 1977 BULLETIN-2008 UL Standard for Safety for Component Connectors for Use in Data@ Signal@ Control and Power Applications (COMMENTS DUE: February 8@ 2008)
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.These requirements apply to devices categorized as follows (See Figure 1.1 ):a) Type 0 rated less than 8.3 A and less than 30 V rms (42 V peak);b) Type 1A rated less than 8.3 A and from 30 V up to and including 600 V ac or dc@ or both;c) Type 1B rated from 8.3 A up to and including 200 A@ and less than 30 V rms (42 V peak);d) Type 2 rated from 8.3 A to less than 31 A and from 30 V up to and including 600 V ac or dc or both;e) Type 3 rated from 31 A up to and including 200 A and from 30 V up to and including 600 V ac or dc@ or both.f) Type 4 rated from greater than 200 A up to and including 1000 A@ and up to and including 600 V ac or dc.Type designations used in this Standard only serve as a guide to determine appropriate requirements@ and do not represent an assigned rating. A device not assigned a current rating is considered either to be Type 0 or Type 1A depending upon the assigned voltage rating.This standard does not directly apply to the following but may supplement other applicable standards:a) Devices produced integrally with flexible cord or cable that are covered by the Standard for Cord Sets and Power-Supply Cords@ UL 817;b) Devices intended for connection to the branch circuit@ such as attachment plugs@ cord connectors@ receptacles@ inlets@ and outlets@ that are covered by the Standard for Attachment Plugs and Receptacles@ UL 498;c) Devices solely intended for direct connection to the branch circuit in accordance with the National Electrical Code@ NFPA 70@ and that are provided with contacts of the pin and sleeve type@ covered by the requirements for plugs@ receptacles@ and cable connectors of the pin and sleeve type@ UL 1682;d) Devices consisting of wiring terminals and supporting blocks intended for the connection of wiring that are covered by the Standard for Terminal Blocks@ UL 1059;e) Devices intended for use with telecommunications networks@ that are covered by the Standard for Telephone Equipment@ UL 1459@ or the Standard for Communications Circuit Accessories@ UL 1863;f) Devices such as wire connectors and soldering lugs that are covered by the Standards for Wire Connectors ?C For Use With Copper Conductors@ UL 486A; Splicing Wire Connectors@ UL 486C; or Equipment Wiring Terminals@ UL 486E;g) Devices such as quick-connect terminals that are covered by the Standard for Quick Connect Terminals@ UL 310.
