3.7 Enclosure
The rugged steel switch enclosure is supplied with four door
hinges, regardless of enclosure size, to insure 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 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 dura-
ble 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 (Table 4).
