How to Install Hubs on the A42SA3212LPPL Enclosure

Instructions for installing watertight conduit hubs into the A42SA3212LPPL enclosure, ensuring proper bonding and conduit entry.

Estimated time: 30m

Tools needed:

Hole saw or Greenlee-type punch, Wrench (for tightening hubs)

Supplies needed:

Approved watertight, rigid conduit hubs, Enclosed external toothed lockwasher, Nuts for securing the panel

  1. Prepare the Enclosure for Hub Installation

    Determine the desired location for conduit entry (top, bottom, or side). Use the provided table to find the recommended opening diameter based on the trade size of the conduit you will be using. Use a hole saw or Greenlee-type punch to cut the required holes in the enclosure.

  2. Install the Conduit Hub

    Install the approved watertight, rigid conduit hub according to the hub manufacturer's instructions. Ensure the hub is properly seated in the cut opening.

  3. Ensure Panel Bonding

    Install the enclosed external toothed lockwasher under one of the nuts that secure the panel. This ensures electrical bonding between the panel and the enclosure.

  4. Secure the Hub

    Tighten the hub's securing mechanism (e.g., locknut) to firmly attach it to the enclosure. Verify that the connection is watertight.
