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. One method is to clamp the
sensors around all feed wires for each phase (no additional reading multiplier
required). The second way to monitor parallel feeds is to clamp the sensor around one
of the feed wires for each phase, and when you read the kWh 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 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 by one meter because they are different
power sources. When you parallel current sensors, all loads must be from the same
voltage source.
Q. I have 5 breakers in one subpanel I would like to monitor with one 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 meter to work.
What should I do?
A. Before removing the unit, contact E-Mon’s technical support department at (800)
334-3666. Our technical support experts will assist you in detailed troubleshooting of
the meter installation and assist you in getting the meter functional without having to
remove and return the unit.
