I’m very interested in getting an IoTaWatt setup to monitor my house. I’m in the US and my panel and wiring is setup for 200A service. However, I read this article at Open Energy Monitor (US 200 Amp Service explained or Do I need a 200 Amp CT? - Hardware - OpenEnergyMonitor Community) that discusses the fact that you probably don’t really have 200A service even if your panel is setup for it. So, I can’t decide if I should get 100A CTs or 200A CTs from the stuff website with my bundle.
What would happen if, in fact, I do exceed 100A routinely at my service panel and I had 100A CTs? Would I just lose resolution? Or would I damage the CTs and potentially put myself in a dangerous situation with regard to fire in the service panel? Should I just stick with a 200A CT to be safe?
