Wire Gauge: For use on cable that is 700 MCM or smaller. It is best to measure your wire diameter in millimeters, rather than use the MCM wire size. This is because the insulation thickness varies materially from one wire manufacturer to the next. It is much better to oversize your CT than to undersize it.
Selected with accuracy and ease of installation in mind.
For use with our Omnimeter line of electric kWh meters.
Our Split Core (open-able) CTs can be a savings overall in the labor cost savings. Simply clip these around the wires being read. Secure them in place with a zip tie.
Our EKM Omnimeter can be programmed internally to be used with 400 amp CTs. If you do not plan to read your Omnimeter directly with a USB Converter (necessary for programming the Omnimeters), please be sure we set the CT ratio to 400 amps for you.
