• See pages J1-J22
• Blank adapter plates on pages F61
IMPORTANT
• Disconnect switch or circuit breakers, operat-
ing handle and operating mechanism are not
furnished with enclosure and must be ordered
separately from the disconnect manufacturer
• Oper at or adapter plates are required with the
modular flange disconnect enclosure only and
must be purchased separately. Modular non-
disconnect enclosures do not require a opera-
tor adapter plate. See page F61 to select the
proper operator adapter for the brand and
type of disconnect being used
• Disconnect ordering information is located on
page F44
• Review space occupied by disconnect draw-
ings on page F43 and disconnect tables on
pages F51-F60 to determine if the disconnect
device you are using will fit the enclosure size
you have selected
A modular enclosure sy stem consists of:
• A disconnect (master) enclosure
• Any quantity of slave enclosures
• Gasket kits to be used between enclosures
• End plate
• An operator adapter plate or blank adapter
plate
• Disconnect device (order from disconnect
manufacturer)
Single and Two Door Enclosures
• Left side is open (see drawings on pages F41
and F42)
• Master door hinged on left
• Master door activates mechanical interlock
which prevents slave enclosures from being
opened first
• Doors may be closed in any order
Single and Two Door Slave Enclosures
• Both sides are open (see drawings on pages
F41 and F42)
• Door cannot be opened until master enclo-
sure is opened or the interlock is defeated

Applications
Modular single-door and double-door Modular
free-standing enclosures are designed to be
bolted together in a variety of lengths and com-
binations to meet the customer’s specific appli-
cation. Modular disconnects enclosures are
designed to house the following flange-mounted
disconnect switches and circuit breakers:
The Wiegmann universal cutout is used in large
freestand and floorstand enclosures. Operator
Adapter Kits are required in order to install the
various manufacturers’ hardware. Note that 400
A (or greater) disconnect switches and 600 A (or
greater) circuit breakers need to use the “Large”
or “High Amp” cutout, which is provided in the
WA21ABVA kit for Allen-Bradley variable-depth
disconnect switches or the WA21ITE kit for
Siemens ITE Max-Flex
™
(and select other manu-
facturers) flex-cable devices. The “Large” or
“High Amp” cutout accepts the larger operating
handle whose mounting hole centers are 6.500-
in. apart.
Allen-Bradle y
• 1494V disconnect switches with flange-mount
variable depth operating mechanisms and
1494V flange-mounted variable depth operat-
ing mechanisms for circuit breakers
• 140U flexible cable operating mechanisms and
140U molded case circuit breakers
• 1494C cable-operated disconnect switches
with flange-mount handles
• 194RC cable-operated flange-mount handles
