GREEN CLASS NET METER
41 62-0416-01
Q. The load I need to monitor has parallel feeds. How do I install the current sensors
for this application?
A. There are two ways you can monitor parallel feeds. The easiest and preferred
method is to clamp the sensors around all feed wires for each phase. The second
way to monitor parallel feeds is to clamp the sensor around one of the feed wires for
each phase. When you read the Green Class Net meter, the final reading must be
multiplied by the number of feed wires for each phase.
Q. I have two subpanels I would like to monitor with one Green Class Net meter. These
subpanels are fed by different transformers in the building. Can I parallel sensors
and monitor both panels with one meter?
A. No. These panels cannot be monitored with one meter because they are different
power sources. When you parallel current sensors, all loads being monitored must
be from the same voltage source.
Q. I have 5 breakers in one subpanel I would like to monitor with one Green Class Net
meter. Can this be done without having to parallel current
sensors?
A. Yes. Simply run all the breaker wires through one set of current sensors. Make sure
all A-phase circuits are run through the A-phase sensor, and the same for B & C
phases. The meter should be sized by the highest amount of current being
monitored by one sensor.
Q. I’ve gone through the troubleshooting guides and I still can’t get my Green Class
Net meter to work. What should I do?
A. Before removing the unit, contact E-Mon’s technical services department at (800)
334-3666. E-Mon’s technical department will assist you in detailed troubleshooting
of the meter installation and assist you in getting the unit running without having to
remove and/or return it.
