Transfer Switch Enclosure
The standard switch enclosure is a National Electrical
Manufacturer's Association (NEMA) and UL/CUL 3R
type. UL/CUL and NEMA 3R (indoor/outdoor rated) type
enclosures primarily provide a degree of protection
against falling rain and sleet; are undamaged by the
formation of ice on the enclosure.

Load Management Options
Load management systems are designed to work
together to prevent a generator from being overloaded by
large appliance loads. A Smart A/C Module (SACM) is
standard in these switches. An optional Smart Manage-
ment Module (SMM) is also available.
Smart A/C Module (SACM)
Up to four air conditioner loads can be managed by the
SACM. The SACM manages the loads by "shedding" the
connected loads in the event of a drop in generator fre-
008981
quency (overload). Loads to be "shed" are in four priority
levels on the module.
See

for an air conditioner. To control an air conditioner, no
additional equipment is required. Internal normally closed
relays interrupt the 24 VAC thermostat control signal to
disable the air conditioner load.
