What does Article 503 cover concerning electrical equipment?

• A. High voltage requirements
• B. Fire and explosion hazards
• C. Health and safety measures
• D. Energy efficiency standards

Answer: (B)

Article 503 addresses fire and explosion hazards specifically related to areas involving hazardous locations and the use of electrical equipment. This article outlines the necessary precautions and installation procedures to mitigate risks associated with combustible materials, flammable gases, vapors, and dust. By focusing on fire and explosion prevention, the article ensures that electrical installations are maintained to protect both people and property from the dangers posed by potentially explosive environments. High voltage requirements would pertain to a different section that deals with voltage-specific regulations. Health and safety measures are likely covered in a broader context but not specific to electrical equipment as defined under Article 503. Energy efficiency standards are typically found in sections that deal with energy consumption and environmental impact, which are separate from the hazards addressed in Article 503.
