UL 310:2001 pdf download Electrical Quick-Connect Terminals
Scope
1.1 These requirements apply to 0.110-, 0.125-, 0.187, 0.205-, and 0.250-inch (2.8-, 3.2-, 4.8-, 5.2, and6.3-mm) wide electrical quick-connect wiring terminations, both connectors and tabs, for use in electricaequipment that comply with the requirements for such equipment.
1.2 These requirements apply to terminals intended for use with one or two Nos, 22 – 10 AWG (0.32 -5.3 mm%) copper conductors for internal wiring connections in electrical equipment and for the fieldtermination of conductors to electrical equipment.
1.3 These requirements do not apply to terminals for use with aluminum conductors.
1.4 These requirements do not apply to multi-pole terminals. Multi-pole terminals are covered by theStandard for Attachmment Plugs and Receptacles, UL 498.
1.5 A product that contains features. characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire or of electric shockor injury to persons shal be evaluated using appropriate additional component and end-productrequirements to maintain the level of safely as originally anticipated by the intent of this standard. Aproduct whose features,characteristics, components, materials,or systems conflict with specificrequiremments or provisions of this standard does not comply with this standard. Revision of requirementsshall be proposed and adopted in conformance with the methods employed for development, revision, andimplementation of this standard.
