11.0 FREQUENTLY ASKED QUESTIONS
Q. When providing line voltage to the meter, can I tap off of the same breaker I am
monitoring?
A. Yes, the voltage can be pulled from the same breaker being monitored.
Q. Can the meter's line voltage wires be run in the same conduit as the sensor leads?
A. Yes. There will be no effect if the sensor leads and line voltage wires are run in the
same conduit.
Q. Can the meter's communication wires and line voltage be run in the same conduit?
A. It is not recommended to run these wires together due to noise concerns and their
effects on the communications signal integrity. Communications wires can be
routed separately using a 1/2" conduit port.
Q. How do I find the cost for kWh and kW to bill my tenants?
A. Your local utility bill should list the cost per kWh and kW. If not, simply call your
utility and ask them to provide you with the cost per kWh and kW.
Q. What size wire do I use for the line voltage leads?
A. These wires are normally sized at #14 AWG, but be sure to confirm this
requirement with your local and national electrical code requirements.
Q. What size wire should I use to extend the current sensor leads?
A. These wires are normally 14-22 AWG, twisted-pair arrangement. Consult your
electrical code for proper wiring requirements.
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.
