2. Service: Three Phase, 4-Wire WYE Service with 3 PT Voltage and 3 CT
Connection for Metering 8 Three Phase Loads: MP200-Y
NOTES:
• All CTs must have one side grounded to reduce shock hazard.
• You must order the MP200-Y unit for the three phase operation.
• EIG highly recommends using shorting blocks like the EI SB-6TC so that the meter
can be removed from service while the CT is energized.
• 8 shorting blocks should be used for all 8 three phase circuits.
