What is the minimum thickness of a plate or bushing used to protect wire?

The minimum thickness of a plate or bushing used to protect wire is 1/16 inch. This specification is essential to ensure that the wire insulation is adequately shielded from any sharp edges or potential abrasion when passing through various surfaces or conduits. A thickness of 1/16 inch provides enough material to absorb impact and prevent damage to the protective wire insulation while ensuring compliance with safety standards.

Utilizing a thickness less than this can compromise the protective capabilities of the plate or bushing, potentially leading to wear on the wire insulation and increasing the risk of electrical faults or failures. To effectively safeguard electrical installations, it's important to adhere to these guidelines and specifications set forth in electrical codes and standards.
