Hello everyone. After searching online for help, I finally gave up and decided to register here.
Background: I recently finished renovating a commercial property into living space for our family. The old service had a 100A standard service as well as a 100A 3 phase supply.
I added 2 new sub panels (1 for both). Regarding the 3 phase supply, I am using 2 of 3 legs to supply my 240 appliances.
One reason for this move was because we have a ton more space. I totally expected a higher utility bill. But not at the level I'm seeing for sure.
I have tested a few appliances with my clamp meter, but my main question involves measuring at the panels.
Can I use my clamp meter on all incoming service feeds to determine amperage - then calculate kWh from those? My question is how does the calculation change on the individual 3 phase lines?
I'm not sure if I do the standard V x I across the board? Hopefully I have explained things properly. Please let me know if you need more details in order to offer insight.
Thanks,
Steve
