3.2.1 CT Multipliers
Note The following table MUST BE used to verify the correct current readings, based on the
rating of the CT installed.
Note The multiplier that corresponds with the CT rating MUST BE applied to the current reading
shown on the display of the EPM4500 by multiplying that reading by the multiplier shown
above. The multiplier MUST also be applied in the same manner when calculating kW and
kWh. Failure to use the appropriate multiplier will result in an incorrect diagnosis of the
meter's functionality and incorrect revenue billing.
