PREFERREDCUTOUT OVERVIEW
APPLICATION
Enclosures having the preferred cutout are sized for use with
up to 200A disconnect switches and up to 400A circuit breakers
unless otherwise specified. The preferred cutout accepts the
smaller operating handle whose mounting hole centers are 4.688
in. apart. Preferred cutouts are standard in mild steel wall-mount
enclosures, modular enclosures and some select large mild steel
enclosures. They are also present on all standard stainless steel
offerings. 400 A (or greater) disconnect switches and 600 A (or
greater) circuit breakers require the “Large” or “High Amp” cutout.
This cutout accepts the larger operating handle whose mounting
hole centers are 6.500-in. apart. This large cutout is only available
on PROLINE-DD Disconnect Packages and Type 1 Free-Stand
Enclosures.
Operator adapter for preferred cutouts must be ordered separately
to be used with A21S, A28S4, A4S and WS2D enclosures. Preferred
cutouts are designed to house the following:

These enclosures will NOT accept Square D Class 9422 bracket-
mounted disconnect devices, Class 9422TG1 or TG2 devices.
ORDERING
Order the disconnect switch, operating handle and operating
mechanism separately. See Technical Information in the Hoffman
Specifier’s Guide for wire bend space available when various
manufacturers’ disconnect switches are installed. Check the
enclosure dimension drawings to verify the chosen disconnect
switch will fit in the enclosure.
