Hi Bill,

    The 'y' refers to the voltage between phases when connected in a 3-phase
y configuration, but the winding of the actual transformer is simply 8400V.
This is what is known as a potential transformer and according to the data
sheet is rated at 1500W. Any ballast that causes it to draw more than that
will require intermittent duty use, but these are rugged xformers and can
take brief overloads easily.
