How does Article 225 address the routing of underground cable in relation to paving?

• A. Cable must be laid on the surface
• B. Cable should be buried at a depth that allows for future paving
• C. Cable can be installed directly under the paving
• D. Cable must be installed only during dry conditions

Answer: (B)

Article 225 of the National Electrical Code (NEC) provides guidelines for the installation of outside branch circuits, including specific provisions regarding underground installations. When dealing with paved areas, it’s crucial to ensure that underground cables are installed at the appropriate depth. The correct approach, which is supported by Article 225, states that cables should be buried at a depth that accommodates any future paving. This ensures that the cables are not inadvertently damaged during paving activities and maintains safety and accessibility for future maintenance or repairs. Installing the cable at an adequate depth helps to protect it from physical stress and potential impacts from construction activities, which is essential in maintaining the integrity of the electrical system. By following this guideline, installers can avoid costly repairs and ensure compliance with safety standards. This attention to proper installation depth reflects industry best practices for long-term reliability and meets the safety requirements outlined in the NEC.
