DISCONNECT MOUNTING SPACE
Disconnects are located by dimension E1. Wiring space W1 is
available when disconnect is installed in the enclosure.
See the Hoffman Specifier’s Guide Technical Information chapter
for E1 Spacing by Enclosure Height for various disconnect switch
manufacturers.
Refer to National Electrical Code® 2005 article 430.10(B) for
wiring space required for line side conductors to be connected to
disconnect. Verify your application to determine if wiring space is
adequate.
Consult Space Occupied by Disconnect drawing to determine whether
the disconnect device you are using will fit the enclosure size you have
selected.
SEQUESTR™ PREFERREDCUTOUT OVERVIEW
APPLICATION
The SEQUESTR™ enclosures have the standard preferred cutout
on the left-hand flange. They accept left-hand 1494V Allen-Bradley
variable-depth devices, up to 200A, and left-hand Class 9422 Square
D variable-depth devices, up to 200A.
SEQUESTR cutouts are designed to house the following:
Allen-Bradley Bulletin 1494V DSX left-hand disconnect switches
with flange-mount variable depth operating mechanisms and
Bulletin 1494V flange-mount variable-depth operating mechanisms
for circuit breakers.
These enclosures will NOT accept Allen-Bradley Bulletin 1494F
disconnect devices or Bulletin 1494D circuit breaker operators.
Schneider Square D® Class 9422 disconnect switches with flange-
mount left-hand variable-depth operating mechanisms and Class
9422 flange-mount left-hand variable-depth operating mechanisms
for circuit breakers.
These enclosures will NOT accept Square D Class 9422 bracket-
mounted disconnect devices, Class 9422TGI or TG2 devices.
ORDERING
Disconnect switch (or circuit breakers), operating handle and
operating mechanism are not furnished with enclosure. Consult
the Hoffman Specifier’s Guide Technical Information chapter for
wire bend information and hoffmanonline.com for disconnect
manufacturer information. Consult drawings to match the
disconnect device you are using with the correct enclosure size.
A complete assembly consists of:
1. An enclosure
2. Door interlock brackets
3. Door latching system (2-point on SEQUESTR Enclosure,
3-point on main control cabinet doors)
4. Instructions to locate and install disconnect
5. Grounding hardware kit
6. Conductive panel in SEQUESTR External Disconnect
