I have an indoor installation where a panel-board will be mounted above its 75kva feeder transformer. The work space requirements defined in 110.26 have been accounted for.
My question is, whether there is a code requirement that would prevent me from entering the transformer through the top, from the bottom of the panel-board, given that the transformer can accommodate top entry?
I have not been able to find anything that addresses this directly. Only a guideline that side or bottom entry is preferred because of the heat rising from the transformer and prematurely aging the cable insulation.
