I require the physical connection (for voltage measurements) taken from a breaker in the panel or even a subpanel. I have never seen one of these "gee whiz" devices with a service rating or even close to such. They were and still required on certain Federal Gov't jobs due to supposed energy savings that can be had from monitoring, however, though tools are installed for remote monitoring, I have yet to see one be monitored. No ones job and no time to waste on frivolities at least non-military. It is not a manufacturing plant where you can actually get hints of failing equipment. Umm, you did not hear his form me.
