## Problem

A concern was raised regarding the fitment of Molded Case Circuit Breaker (MCCB) covers provided with bus straps (part number 72311176185). The covers were reported as not fitting over the MCCBs, potentially impeding project completion.

## Investigation and Resolution

Upon examination of a physical MCCB cover from stock against the provided catalog and drawings, it was determined that there was no defect in the cover itself. The design of the MCCB cover is such that it is meant to sit under the metal plate of the MCCB.

The apparent fitment issue may stem from a misunderstanding of the assembly process or incorrect installation. The MCCB cover is designed to fit snugly and protect the circuitry; however, it must be positioned correctly to fit.

To resolve the reported fitment issue, the following steps are recommended:

1. Ensure that the MCCB cover is aligned properly with the breaker.

2. Confirm that the cover is the correct part for the specific model of the MCCB.

3. Verify that the metal plate is not obstructing the cover and that it is seated under the metal plate as designed.

4. If the cover still does not fit, consider consulting the product manual or reaching out to technical support for further guidance.

No replacement cover is necessary as the issue does not relate to a manufacturing defect but rather to the installation process.
