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 pad-
lock latches. Cable entry holes are the
customer’s responsibility.
The door is used to mount a variety of
lights, switches, and push buttons,
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 pre-treatment cleaning
system prior to painting to insure 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
