Overview

The nVent Sequestr External Disconnect Package (SKU: A90XD7820FTCLPG) is a Type 12-rated enclosure designed to enhance electrical safety by isolating incoming power from the main enclosure during maintenance or service operations. This external disconnect solution mitigates arc flash risks, protecting personnel and equipment while ensuring compliance with NFPA 70E and OSHA safety standards. Shipped as a pre-assembled unit, the package includes a disconnect switch and fuse block or circuit breaker mounted in the external enclosure, with dedicated terminal connections to safely route power to the main enclosure. This industrial-grade external disconnect package is engineered for environments where electrical safety and operational reliability are critical. The Type 12 enclosure (90.12 x 78.50 x 20.12 mm) provides robust protection against dust, dirt, and non-corrosive liquids, making it ideal for manufacturing plants, data centers, commercial buildings, and utility installations. The gray steel construction ensures durability and corrosion resistance, while the two-door design allows for clear separation of power sources and easy access for maintenance. Professionals select the nVent Sequestr External Disconnect Package for its ability to simplify lockout/tagout (LOTO) procedures, reduce downtime during equipment servicing, and enhance overall electrical safety. The external mounting of the disconnect switch enables technicians to isolate power without entering the main enclosure, significantly lowering the risk of arc flash incidents. This solution is particularly valuable in applications where frequent equipment access is required, such as motor control centers, panelboards, and industrial machinery. Installation is streamlined thanks to the pre-wired terminal connections, which reduce on-site labor and minimize potential wiring errors. The package is designed for new installations, ensuring compatibility with standard electrical infrastructure. nVent’s reputation for engineering high-performance electrical solutions is underscored by this product, which leverages decades of expertise in thermal management, connectivity, and safety solutions. Key applications include: - **Manufacturing facilities** requiring frequent equipment maintenance. - **Data centers** where power reliability and safety are paramount. - **Commercial buildings** with stringent electrical safety regulations. - **Utility installations** needing robust, weather-resistant enclosures. - **Industrial automation** environments where arc flash mitigation is critical.

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.
