Issue:
Can a transformer with the T6H voltage code (480V - 240V) be wired using the taps to obtain 208V on the output?

Product Line:
Low Voltage Transformers

Environment:
Application

Cause:
Wiring a transformer

Resolution:
No. The largest tap on the T6H transformers is 504V. If you connect 480V incoming to Primary tap #1 (504V) it will drop the output voltage from Secondary phase to phase from 240V down to about 228V.  It is not possible to drop the 240V  lower than that, because you are out of "Higher Voltage Taps".
