2.9 Measuring Multiple Loads with One Meter
(1) The loads must be the same configuration and come from the same power
source.
(2) Each meter can accept 3 loads at most, each load needs to have its own set
of CTs and each CT must be of the same rating.
(3) The load wires threaded through the CTs must be in the same direction. Each
of the CTs for the same phase on different loads must be connected to the
correct polarity (CT white wire to the CT+ terminal on the meter, and the CT
black wire to the CT– terminal on the meter)
e.g. 1 phase, 2 wire on 3 loads
2.10 Power Supply
The power supply of the Polaris is derived from the phase A voltage. To provide
additional protection for the Polaris, a fuse should be placed between the Polaris
and the power source as shown in each of the electrical wiring diagrams.
