What does Article 110.23 convey about the use of noncurrent-carrying parts?

Article 110.23 of the National Electrical Code (NEC) emphasizes the necessity for noncurrent-carrying parts to be securely connected and protected. This is important because noncurrent-carrying components, such as equipment enclosures, covers, and frames, play a critical role in ensuring the safety and reliability of electrical installations. When these parts are not securely connected, they can become a source of electrical hazards, such as unintended contact with live parts or mechanical failure, leading to potential shocks or short circuits.

By ensuring that noncurrent-carrying parts are securely connected, it limits movement that might expose conductive components and protects against environmental factors that could lead to deterioration or damage. Proper protection—whether through grounding or appropriate barriers—further safeguards individuals from electrical hazards, maintaining the integrity of the installation.

While visual inspections are a good safety practice, they alone do not fulfill the specific regulatory requirements set forth by the NEC for secure connections and protection mechanisms. Permanently installing these parts is beneficial but does not inherently address the need for secure connections and protection. Flexibility in installation could lead to unsafe practices if these noncurrent-carrying parts are not systematically secured, ultimately increasing the risk of unsafe conditions. Hence, the focus on secure connections and
