1 Scope
1.1 These requirements cover current taps and adapters for use in accordance with the National
Electrical Code, ANSI/NFPA-70.
1.3 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
Lampholders, UL 496. Current taps wired to flexible cord are covered in the Standard for Attachment
Plugs and Receptacles, UL 498.
