Does SquareD/Schneider Electric advise the paralleling of Transformer primaries or secondaries?

Issue:
Parallel transformers to increase KVA capacity

Product Line:
LV Transformers

Environment:
Applies to Low Voltage Transformers by SquareD/Schneider Electric

Cause:
Applications can require an increase in KVA capacity from smaller Transformers

Resolution:
Schneider does not recommend parallel of transformer on the primary or secondary.  Because of widely variable internal characteristics of Transformers (even those from the same production run) paralleling of similar Transformer primaries and secondaries is not normally recommended, because of possible complications.  See attached Bulletin 7400DB0701 for more details.
