60A circuits

[toddbecker]

My AC units is on a 60A dual pole circuit. In the installation FAQ it says that the expansion modules support eight 50A circuits.

“How many expansion modules can be plugged into the Vue?
Each Vue can support one Expansion Module that provides individual monitoring for up to eight 50A circuits.”

What do I have to consider when having a 60A circuit bring monitored, will it misrepresent peak load?

Hi @toddbecker the 50A sensors have resolution up to 63A in measurement.   You should be find using the expansion modules on your 60a breaker.

I just purchased your product from Amazon, and I would like to know the minimum load for your 50A CT’s?  Also, do you plan on offering lower amp CT’s that would, potentially, be more sensitive with a lower minimum?

@mukwonago, I found this in the Gen 2 FAQ.  Says 5 watt min reading, but I have a monitored circuit that draws just 3 watts in standby and my Gen 2 Vue reports this very accurately.

Our sensors have physical limitations. Each 200A sensor is accurate with high resolution between 0.04A – 250A (5W – 30kW @ 120V). And each 50A sensor is accurate with high resolution between 0.04A – 63A (5W – 7500W). When you go below those ranges, the sensors will report about 5W of noise. However, when in range, the sensors can resolve differences as low as a handful of watts. The app filters out this noise, so you’ll see no load when the sensors are below the threshold of 5 watts for either the 50A sensors and 200A sensors. However, if you download the raw data, you will see the reported noise – giving a slight discrepancy between the app and the raw data.
