Circuit Level Monitor Comparisons

The circuit level monitor is constructed with modules that each contain a fixed number of channels.   These modules can run as a stand alone monitor or be linked together measure as many circuits as desired.   Modularity gives one the choice to balance cost with the number of circuits to be measured.  To qualify for this category the system must be capable of measuring every breaker pole in a standard 200-amp, 40-circuit panel.

Measuring every circuit in the home requires a separate current transformer or CT to be installed for each 120 volt circuit or two for every 240 volt circuit.  Software must track energy data for each of these circuits.  Some packages even have the ability to make energy saving recommendations based on usage patterns.

Even though a circuit level monitor is normally priced higher than a single or multi-point monitor, the level of detailed data it delivers can provide additional energy savings.  In many cases, this will result in a similar pay back period with greater long term savings, especially in larger homes.
