These requirements cover current taps and adapters for use in accordance with the National Electrical Code, ANSI/NFPA-70.

These requirements do not cover current taps or adapters rated at more than 200 A or for more than 600 V. See 6.1.

These requirements do not directly apply to current taps wired to flexible cord or lampholder adapters but supplement the applicable standards. Lampholder adapters are covered in the Standard for Edison-Base Lampholders, UL 496. Current taps wired to flexible cord are covered in the Standard for Attachment Plugs and Receptacles, UL 498.

These requirements do not cover cord-connected, relocatable power taps intended only for indoor use as a temporary extension of a grounding, alternating-current branch circuit for general use, and which are covered by the Standard for Relocatable Power Taps, UL 1363.

These requirements do not cover the current or voltage conversion circuitry capable of being used in travel adapters.

As used in this Standard, the term device is intended to refer to both current taps and adapters unless specifically stated otherwise.
