Cutler-Hammer automatic transfer switches are avail-
able to meet NFPA110 for emergency and standby
power systems, and NFPA99 for health care facilities
when ordered with the appropriate options.
Since Cutler-Hammer automatic transfer switches use
specially designed molded case switches as the main
power switching contacts, these devices must also be
listed under the additional UL Standard 1087.
Underwriters laboratories uses two basic types of listing
programs — label service and re-examination.
UL1087 employ a label service listing program which
requires an extensive follow-up testing program for list-
ed devices. Standard UL1008 for automatic transfer
switches lists devices under the reexamination program
which only requires a continual physical reexamination
of the components used in the product to ensure consis-
tency with the originally submitted device. Follow-up
testing is not required by UL1008.
Representative production samples of molded case
switches and molded case circuit breakers used in
Cutler-Hammer automatic transfer switches are subject-
ed to a complete test program identical to the originally
submitted devices on an ongoing periodic basis per
UL1087. The frequency of such a re-submittal can be as
often as every quarter for a low ampere device. Any fail-
ure during one of these periodic re-submittals could
result in a loss of the valued UL listing mark.
