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 on the meter if the sensor leads and line voltage wires
are run in the same conduit.
Q. Can the meter communication wires and line voltage wires 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. Communication wires can be routed
separately using the 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 #14 AWG, but be sure to consult your local electrical
codes for proper sizing requirements.
Q. What size wire should I use to extend the current sensor leads?
A. These wires are normally sized at #14-22 AWG, twisted pair arrangement. Consult
your local electrical codes for proper sizing 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. 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?
