Which NEC article covers the requirements for plumbing and health in Electrical Code?

The National Electrical Code (NEC) outlines the electrical standards for safety in the United States, and Article 250 specifically addresses grounding and bonding. This is critically important for plumbing and health because improper grounding and bonding can lead to electrical shock hazards, especially in areas where water is present, such as in bathrooms and kitchens.

Grounding provides a direct path for electrical charges to flow safely into the earth, which is essential in preventing potential electrocutions or fire hazards linked to electrical systems interacting with plumbing. Article 250 ensures that these safety mechanisms are properly implemented, safeguarding both electrical and plumbing systems.

The other articles mentioned focus on different aspects: Article 200 deals with general requirements for branch circuits, Article 300 addresses wiring methods and materials, while Article 400 is specific to flexible cords and cables. These articles do not specifically tackle the intersection of electrical safety with plumbing and health standards, which is why Article 250 is the most relevant in this context.
