Overview

The nVent Sequestr External Disconnect Package, SKU A90XD7824SSFTCLP, is engineered to significantly enhance safety and operational efficiency in industrial electrical installations. This robust 2-door Type 4X enclosure, constructed from premium 304 stainless steel, is designed to mitigate the severe hazards associated with arc flash events. By isolating incoming power from the main electrical enclosure, maintenance personnel can safely access and service internal components without the risk of exposure to live electrical energy. This comprehensive package includes a main enclosure and a dedicated Sequestr box, providing a complete solution for external power disconnection. The disconnect switch and fuse block or circuit breaker are strategically mounted within the external enclosures, with terminal connections facilitating the seamless transfer of power to the primary enclosure. This design ensures that all critical switching and protection devices are accessible externally, further reducing the need to open the main enclosure under live conditions. Manufactured from 304 stainless steel, the Sequestr External Disconnect Enclosure offers exceptional durability and resistance to environmental factors. It is ideally suited for applications in both indoor and outdoor settings, providing reliable protection against non-corrosive or mildly corrosive elements. The brushed finish not only contributes to its aesthetic appeal but also enhances its resistance to surface damage. The 90x78x24 inch dimensions provide ample space for various disconnect switch configurations and associated wiring. Key benefits and features of the nVent Sequestr External Disconnect Package include: * **Arc Flash Mitigation:** Isolates incoming power to prevent arc flash incidents during internal maintenance. * **Premium Construction:** Fabricated from durable 304 stainless steel for superior corrosion resistance. * **Type 4X Rating:** Offers robust protection against water, dust, and corrosive agents, suitable for harsh environments. * **External Accessibility:** Houses disconnect switches and fuse blocks/circuit breakers externally for safe and convenient operation. * **Package Solution:** Includes main enclosure and Sequestr box for a complete disconnect system. * **Retrofit Capability:** Sequestr boxes can be ordered separately to upgrade existing enclosures. This product is an essential component for industries such as manufacturing, power generation, water treatment, and petrochemicals, where electrical safety is paramount. The nVent brand is synonymous with quality and reliability in enclosure solutions, ensuring that this Sequestr package meets the stringent demands of industrial environments. Installation professionals will appreciate the thoughtful design that facilitates straightforward integration into existing or new electrical systems.

How to Safely Handle and Install Large Hoffman Enclosures

This guide provides instructions for safely handling and installing large Hoffman enclosures, emphasizing precautions to prevent injury and equipment damage.

Estimated time: 1h

Tools needed:

Forklift, Overhead lifting device (e.g., crane), Slings with load-rated hooks or shackles, ROLL•A•LIFT™ or similar device (for some models)

Supplies needed:

3000 lb.-rated chain or strap (for securing to forklift mast), Rigging equipment (for overhead lifting)

  1. Read Safe Handling Requirements

    Before moving or installing the enclosure, thoroughly read and understand the 'Large Enclosure Safe Handling Requirements' document that accompanied the enclosure. Ensure the route is clear of obstructions and all personnel are at a safe distance.

  2. Prepare for Movement

    Ensure the enclosure is stabilized before removing any strapping. Verify that the lifting equipment (forklift or overhead device) has a sufficient load rating for the enclosure's weight and size. Only trained and authorized personnel should operate the lifting equipment.

  3. Position Forklift Forks

    For forklift handling, spread the forks to the maximum distance or as dictated by the skid width. Enter the skid from the rear (Side A) of the enclosure. Position the enclosure carefully on the forks, keeping the load against the carriage/mast and tilting the load backward towards the mast.

  4. Secure Enclosure to Forklift

    If using a forklift, secure the enclosure to the forklift mast before moving. Insert a 3000 lb.-rated chain or strap through the eye bolts provided on top of the enclosure and fasten it securely to the forklift mast assembly. Ensure sufficient tension to prevent tipping.

  5. Lift and Transport Enclosure

    Lift the enclosure a minimum distance so the skid is just clear of the floor. Start and stop the forklift slowly and gradually, avoiding jerky movements. Drive slowly with the forks carried as low to the ground as possible. Never attempt to move more than one enclosure at a time.

  6. End Loading/Unloading (if applicable)

    For end loading/unloading on trailers, spread forks to match pallet end slot openings and enter from the narrow side (C or D). Secure the enclosure to the forklift mast using chains or straps. Tilt the mast to take weight off the opposite end and slide/push the enclosure as required. Do not use chains or straps to lift the enclosure.

  7. Overhead Lifting (if applicable)

    If using overhead lifting, attach rigging to the eye bolts, ensuring the angle between lifting cables and the vertical does not exceed 45 degrees. Use slings with adequate load-rated hooks or shackles. Ensure the load rating of the lifting device and rigging is sufficient. Do not use ropes or cables through eye bolts.

  8. Final Placement

    Once the enclosure is at its final location, carefully position it. Ensure it is stable and permanently installed according to any specific product instructions not covered in this general handling guide. Refer to the nameplate or datasheet for model-specific details.
