(Sub) CLAUSE / ANNEX HEADING:
Electric shock hazard under normal operating conditions – Testing on the outside – General

OTHER RELEVANT (Sub) CLAUSES / ANNEXES (as applicable):
See Clause 11 regarding use of UL 60950 power supplies in audio/video products.

DESCRIPTION OF ISSUE:
When power supplies have been evaluated using UL 60950 requirements, which touch current (leakage current) limits are applied?

APPLICATION GUIDELINE:
The touch or leakage current limits noted in Clause 9 of UL 6500 apply regardless of the Standard used to investigate the power supply.

RATIONALE:
The leakage current limits for power supplies investigated using UL 60950 are higher than those in UL 6500 (and in IEC 60065) and are not applicable for use with audio/video products. Although UL 6500 will accept products that employ a UL 60950 investigated power supply, the lower touch current levels in Clause 9.1.1 should be noted and applied.

None
