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specied.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. Mild
steeloperatoradapterplateswithbrandspecicpreferredcutouts
are available for enclosures with a rectangular universal cutout.
Preferred cutouts are designed to house the following:
