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. These 55mm Split Core CTs are easy to install: simply snap these current transformers around the wires being read. They are very compact and can measure the current used in the majority of residential electrical systems. These CTs are designed to be used in conjunction with our Omnimeter line of electric meters for any load from 1/4 amp to 800 amps. These CTs are so easy to install you may
