Correct phasing (associating a CT with the correct voltage reference) is a critical component of the eGauge installation. Ideally, phasing should be verified using a handheld multimeter to determine the phase of a conductor monitored by a given CT. Generally this is less of a concern for split phase services, but three phase services will encounter severe accuracy issues if phasing is incorrect.
eGauge technical support can offer assistance with determining correct phasing. However, correct phasing cannot be guaranteed in this manner. Correct phasing requires on-site verification, performed by a licensed electrician. eGauge does not suggest phase testing or opening electrical panels for any reason unless qualified to do so.
