What quality does the term "mechanical execution" refer to in Article 110.32?

The term "mechanical execution" in Article 110.32 refers specifically to the quality of workmanship in electrical installation. This concept emphasizes that electrical installations must be done with a high level of precision and care to ensure safety and compliance with the National Electrical Code. Proper mechanical execution includes considerations such as the correct installation techniques, proper use of tools, adherence to specifications, and overall attention to detail. By focusing on the quality of workmanship, the code aims to minimize the risks associated with poor installation practices, which could lead to electrical failures or hazards.

Since the focus is on quality, aspects such as speed, cost-effectiveness, or environmental impact do not directly relate to the definition of mechanical execution as outlined in Article 110.32. These factors, while important in the broader context of installation and project management, do not encapsulate the pivotal focus on craftsmanship and quality that "mechanical execution" demands.
