What is the status of weatherproof electrical outlets used on decks and patios in relation to hazardous locations?

Weatherproof electrical outlets used on decks and patios are classified as not approved for hazardous locations. This classification is due to the specific design and purpose of these outlets, which are intended for safety in general outdoor environments rather than environments classified as hazardous. Hazardous locations include areas where flammable gases, vapors, or dust may be present, which require specific equipment designed to prevent ignition sources.

Weatherproof outlets are designed to withstand exposure to moisture and environmental factors, making them suitable for outdoor use, but they do not meet the stringent requirements necessary for hazardous locations that necessitate explosion-proof or intrinsically safe equipment. This distinction is crucial for ensuring safety and compliance with electrical codes that govern installations in potentially dangerous environments. Thus, the correct selection is based on understanding the limitations and intended use of weatherproof electrical outlets.
