Question: Can I use the S3300/S3500 meter in a 3 phase center tapped (high side) delta configuration?

Answer: The meter should not be used in this configuration. The per-phase energy, power, voltage and amperage values in this configuration will be correct, however the Line-to-Line voltage will be calculated for a balanced 3phase system, and will not represent the actual L-L voltage. If the neutral is not connected, the Line-to-Line voltages will be reported for a virtual neutral. (e.g. L-L=240V, L-N=139)
