What is the minimum length of threaded rigid metal conduit required at the point of emergence from an underground location?

• A. 1 foot
• B. 2 feet
• C. 3 feet
• D. 4 feet

Answer: (B)

The minimum length of threaded rigid metal conduit required at the point of emergence from an underground location is indeed 2 feet. This requirement is established to ensure that there is sufficient conduit exposed above ground to facilitate proper termination and maintenance of electrical wiring. The extended length helps in protecting the conduit from damage and allows for a secure connection to other electrical components, ensuring both safety and durability. By extending the conduit above the surface, it significantly reduces the risk of water ingress and other environmental factors that could compromise the electrical system. The 2-foot requirement is aligned with safety regulations and best practices in electrical installations, particularly in hazardous locations where conditions can be variable and potentially dangerous.
