I'm working on the design of low voltage switchgear complying to UL 20 standard (Underwriters Laboratories). In clause 5.7.9 there is a test with incandescent lamps which seems to be demanding. Does anybody know any helpful hint on the selection of the contact material or shape of the contact to comply with the test? Any other suggestion will be helpful.
Thanks.
