Problem: I am planning to monitor whole house power consumption using the setup below. The CT sensors I have are too small for the incoming mains (200 amp USA service, 120-N-120).
Setup: emonTX3.4, RPI3 + emonBase, 9 volt AC-AC power supply. Latest firmware.
Question: Not being an electrical engineer, I need help in finding two CT split core sensors that will fit around my incoming service wires (4/0 ?). I would like some that would require minimal reconfiguration/calibration of the existing system (removing/replacing resistors, recompiling software, etc.). Can anyone suggest a close replacement for the SCT-013-000 but with a larger diameter opening?
I am less interested in cost than ease of installation. I have seen the SCT023R mentioned but don’t know what it may involve to set it up.
As no good deed goes unpunished, I would also ask for help with how to calibrate and install the sensors.
Many thanks in advance for any help from the group.
