V-TYPE PREPACKAGED
TRANSFER SWITCHES
GENERAL
The prepackaged, V-Type transfer switch is rated
100 amps at 250 volts maximum. It is available in 2-
pole configuration only and, for that reason, is
useable with 1-phase systems only.
Prepackaged transfer switches do not have an
intelligence system of their own. Instead, automatic
operation of these transfer switches is controlled by a
circuit board housed in the generator control panel.
ENCLOSURE
The standard prepackaged, V-Type transfer switch
enclosure is a NEMA 1 type ("NEMA" stands for
"National Electrical Manufacturer’s Association").
Based on NEMA Standard 250, the NEMA 1
enclosure may be defined as one that is intended for
indoor use primarily to provide a degree of protection
against contact with the enclosed equipment and
where unusual service conditions do not exist.
