When stacking two Ventilated Transformers one above the other one, how close can the Transformers be?

Allocation of space for Ventilated Transformer installation

Product Line:
LV Transformers

Applies to Ventilated Transformers by SquareD/Schneider Electric

Ventilated Transformers require clearance space between the top surface of the enclosure and any obstruction for proper heat dissipation


There should be at least 36 inches of clearance between the bottom of the top Transformer and the top of the bottom Transformer.
(NOTE: this information does not apply to EX transformers.  Presently, the clearance required between stacked EX has not been determined).
