Enclosure
The rugged steel switch
enclosure is supplied with
four door hinges, regardless
of enclosure size, to ensure
proper support of the door
and door-mounted devices.
The hinges have removable
hinge pins to facilitate door
removal. The doors are
supplied as standard with
thumbscrew and padlock
latches. Cable entry holes are
the customer’s responsibility.
The door is used to mount a
variety of lights, switches and
pushbuttons, depending
upon the options required for
a particular switch. All switch
doors are supplied with a
heavy-duty plastic accessory
panel in place, whether or not
external devices are required.
When lights, pushbuttons or
switches are required, they
are normally mounted in the
plastic door-mounted panel.
Transfer switch enclosures
and some internal steel
mounting plates, such
as the transformer panel
mounting plate, go through
a pretreatment cleaning
system prior to painting
to ensure a durable finish.
Should the enclosure
become scratched and in
need of touch-up paint, use
ANSI 61. All remaining steel
is galvanized.
The standard switch
enclosure is NEMA Type 1
for general indoor use. See
table below.
Power Cables
Power cables are to be
connected to solderless
screw-type lugs located on
the transfer switch switching
devices. Refer to the
separate customer wiring
diagrams supplied with the
transfer switch equipment
for power termination. Verify
that the lugs supplied will
accommodate the power
cables being used. Also verify
that the cables comply with
local electrical codes.
Standard transfer switch
equipment, as supplied
from the factory, will
accommodate the wire
sizes shown in table below.
