Why does the secondary control power transformer fuse on the 8839FLEX58 blow.

Q: Why does the secondary control power transformer fuse on the 8839FLEX58 blow.

Issue: Why does the secondary control power transformer fuse on the 8839FLEX58 blow. Product Line: Transformer Environments: All Causes: Fault conditions Resolution: If there are no short circuits or failed components on the secondary of the control power transformer and the customer has not added any additional field-installed components to the secondary of the control power transformer, this may occur if the line voltage is low. The line and load voltages need to be verified. Also, if no other problems can be found then the secondary control power fuse rating can be increased by one size if it is within the specified tolerance of acceptable value for fuse for that particular transformer.
