7.0 MULTIPLE-LOAD MONITORING

The E-Mon D-Mon Green Class Net meter provides extreme flexibility by allowing

additional sets of current sensors to be used in parallel so multiple load locations can

be monitored by one meter. This feature allows a totalized display readout from two or

more load circuits.

You may use parallel sensors to monitor specific breakers from one panel, specific

breakers from more than one panel, two or more complete panels, etc.

When paralleling current sensors, the following rules must be followed for accurate

readings:

1. Current sensors must be installed in complete sets of three, with a maximum of

three sensors installed in parallel per phase.

2. All sensors used in parallel must be of the same amperage rating (all 100-amp,

all 400-amp, etc.) The rating is determined by the current rating of the meter. For

example, a 200-amp meter must use extra sets of 200-amp current sensors.

3. All locations being monitored must have the same power source. A 480-volt

meter cannot monitor a 208-volt load, nor can a meter monitor two-480 volt loads

if they are from different originating power sources or from different transformers.

4. 4. Multiply the meter display readings by the number of sets of current sensors

installed. Example: Meter readings of 5 kWh with 2 sets of current sensors - 10

kWh is the actual usage. (5 x 2=10.)
