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 (R) 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. SEQUESTRTM Preferred-Cutout Overview Schneider Square D(R) Class 9422 disconnect switches with flangemount 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 bracketmounted disconnect devices, Class 9422TGI or TG2 devices. ORDERING APPLICATION 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. The SEQUESTRTM 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. A complete assembly consists of: 1. An enclosure SEQUESTR cutouts are designed to house the following: 2. Door interlock brackets Allen-Bradley Bulletin 1494V DSX left-hand disconnect switches 3. Door latching system (2-point on SEQUESTR Enclosure, with flange-mount variable depth operating mechanisms and 3-point on main control cabinet doors) Bulletin 1494V flange-mount variable-depth operating mechanisms 4. Instructions to locate and install disconnect for circuit breakers. 5. Grounding hardware kit These enclosures will NOT accept Allen-Bradley Bulletin 1494F 6. Conductive panel in SEQUESTR External Disconnect disconnect devices or Bulletin 1494D circuit breaker operators.
