A
Answer:
Hello Homer and thanks for the question.
Protection against physical damage is required for transformers in accordance with Section 450.8(A). Section 110.27(B) also provides a general requirement for protection of equipment (including transformers) where subject to phyiscal damage. The NEC stops short of indicating that bollards have to be used for this specific purpose, but it is a pretty common method to use.
