Overview

Enhance electrical safety and operational efficiency with the nVent Sequestr Retrofit External Disconnect Enclosure (SKU: AXD18SS). This robust Type 4X enclosure, constructed from durable 14-gauge 304 stainless steel with a #4 brushed finish, is engineered to significantly mitigate arc flash hazards by relocating incoming power disconnects away from main control enclosures.

How to Install the Sequestr External Disconnect Enclosure

This guide provides step-by-step instructions for installing the Sequestr external disconnect enclosure to a control enclosure, ensuring proper mounting, wiring, and initial setup.

Estimated time: 1h

Tools needed:

Screwdriver, Drill, Volt meter, Wire strippers

Supplies needed:

Mounting screws, Terminal connectors, Hoffman hole seal, Hoffman blank adapter plate

  1. Power Down the System

    Turn off the local disconnect in the control enclosure and the feeder disconnect. Wear appropriate Personal Protective Equipment (PPE) and test for power using a volt meter.

  2. Prepare the Control Enclosure

    Remove the existing disconnect from the control enclosure and seal the hole with a Hoffman hole seal. Cover all components in the control enclosure to protect them.

  3. Mount the Sequestr Enclosure

    Remove the subpanel from the Sequestr enclosure. Drill a hole for the power line entrance, then hang the Sequestr enclosure on the control enclosure using M6x16mm bolts and secure it with washer head cap screws.

  4. Install Circuit Breaker/Disconnect Switch

    Drill mounting holes for the circuit breaker or disconnect switch on the panel. Install the device according to the manufacturer's instructions and secure the panel back into the Sequestr enclosure.

  5. Connect Wiring

    Install conduit and connect wires to the incoming side of the circuit breaker/disconnect switch in the Sequestr enclosure. Ensure all connections are secure and properly insulated.

  6. Power Up the System

    Remove any protective coverings, ensure the operator handle is in the 'OFF' position, close and latch the Sequestr and control enclosure doors, then turn on the feeder disconnect switch and verify system operation.
