Which article covers the general installation requirements of transformers?

• A. 450
• B. 110
• C. 240
• D. 695

Answer: (A)

Transformers have a dedicated article in the code that specifically covers how they should be installed. This article lays out the general installation requirements, including where and how to mount transformers, the required clearances for cooling and service access, ventilation considerations, enclosure or protection from physical damage, proper wiring methods and terminations, insulation, grounding and bonding, and how the unit should be protected within the overall electrical system. It’s the reference you’d consult whenever the question is about how transformers are to be installed rather than about general electrical installation rules or other, more specialized topics. The other options refer to different parts of the code that address broader installation practices or other topics (like overcurrent protection or equipment-specific rules), not the transformer-specific installation guidance.
