General
The “W/V-Type” transfer switch is rated 100 amps at
250 volts maximum. It is available in 2-pole configura-
tion only and, for that reason, is usable with 1-phase
systems only.
Transfer switches do not have an intelligence sys-
tem of their own. Instead, automatic operation of
these transfer switches is controlled by a circuit board
housed in the generator control panel.
encloSure
The “W/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.
