Since Eaton ATSs utilize specially
designed switches and/or switching
devices as the main power switching
contacts, these devices must also be
listed under the additional UL Standard
1066. UL utilizes two basic types of list-
ing programs: a) Label Service and b)
Re-examination. UL 1066 employs a
label service listing program which
requires an extensive follow-up testing
program for listed devices. Standard
UL 1008 for ATSs lists devices under the
re-examination program which only
requires a continual physical re-exami-
nation of the components used in the
product to insure consistency with the
originally submitted device. Follow-up
testing IS NOT required by UL 1008.
Representative production samples of
switches and switching devices used
in Eaton ATSs are subjected to a com-
plete test program identical to the
originally submitted devices on an
ongoing periodic basis per UL1066.
The frequency of such a re-submittal
can be as often as every quarter for a
low ampere device.
Environmental
Seismic
With proper installation and by includ-
ing Option 42 which includes specially
designed cleats, the Magnum transfer
switch is a Seismic Certified Transfer
Switch with certificate for application
that is Seismic Zone 4 under the
California Building Code, the Uniform
Building Code, and BOCA.
Operational Conditions
Normal operation in an electrical
equipment room for indoor applications.
Outdoor applications can subject units
to falling rain, freezing temperatures,
and 95% humidity (non condensing).
Ambient temperature for operation is
between -20 and +65°C (-4 and 149°F).
