What is required for switchboards, switchgear, panelboards, and motor control centers located outdoors?

Installation in identified enclosures is essential for switchboards, switchgear, panelboards, and motor control centers located outdoors to protect the equipment from environmental factors, such as moisture, dust, and temperature extremes. The National Electrical Code specifies that these electrical components must be housed in enclosures that are specifically designed and rated for outdoor use. This ensures that the equipment operates safely and efficiently while minimizing the risk of damage and electrical hazards.

Identified enclosures provide adequate protection while complying with safety standards. Equipment that is not properly enclosed may be susceptible to physical damage, corrosion, and malfunction, particularly when exposed to rain, snow, or high humidity. Recognizing and adhering to these requirements is crucial for maintaining the integrity of electrical installations in outdoor locations.
