What is the minimum distance required between protective assemblies and mechanical appliances?

The minimum distance required between protective assemblies and mechanical appliances is crucial for ensuring safety and proper operation. This distance helps to prevent any potential contact that could lead to wear or damage to the assemblies or the appliances. A one-inch separation is specified to allow for adequate airflow, reduce the risk of overheating, and ensure that maintenance and inspection can be carried out safely and effectively. This provision is part of the International Mechanical Code to enhance safety and performance standards in mechanical installations. By maintaining this specified distance, it minimizes risks and adheres to best practices in HVAC and related fields.
