5.0 MONITORING MULTIPLE LOADS WITH

ONE METER

The Class 2000 meter provides extreme flexibility by allowing additional sets of current

sensors to be used in parallel so that 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:

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

three sensors installed in parallel per phase.

Rule 2: All sensors used in parallel must be of the same amperage rating (i.e. 100

amp, 200 amp, etc.) The rating is determined by the current rating (amperage) of the

Class 2000 meter. For example, a 200 amp meter must use extra sets of 200 amp

current sensors.

Rule 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 or 208 volt loads

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

Rule 4: The display readings must be multiplied by the number of sets of current

sensors installed. E.g. meter reading of 5 kWh with 2 sets of current sensors....5 x 2 =

10 kWh (actual usage.)

NOTE: One set of current sensors equates to three sensors, one per phase.

The multiplier only applies when extra sets of current sensors are

installed on one meter. Therefore, if you are using only one set of three

sensors (one per phase) the multiplier is not required.
