When planning installations, what clearance requirements should be consulted for safety?

• A. NEC Article 220
• B. NEC Article 225
• C. NEC Article 230
• D. NEC Article 240

Answer: (B)

The correct answer focuses on NEC Article 225, which specifically deals with the requirements regarding the installation of branch circuits, feeders, and services that are outside of buildings or structures. This article addresses the necessary clearances to ensure safe installation and operation, particularly in relation to overhead and underground installations. Clearance requirements may include specifications for distances from structures, ground level, and other utility lines, helping to prevent hazards that could arise from accidental contact, environmental factors, or future construction activities. Consulting NEC Article 225 ensures that installations comply with safety standards and minimize the risk of electrical faults or accidents. On the contrary, while NEC Article 220 pertains to load calculations and Article 230 addresses services and the service entrance conductors supplying power to buildings, their focus does not specifically encompass the clearance and spacing requirements relevant to outdoor installations. Article 240 covers overcurrent protection, which, while an important aspect of electrical safety, does not detail clearance guidelines for planning installations. Thus, NEC Article 225 is the most pertinent resource for clearance requirements in outdoor settings.
