Wire Gauge: For use on cable that is ~2000 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.
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 line of electric meters for any load from 1/4 amp to 800 amps.
These CTs are so easy to install you may see an overall savings in reduced labor costs to offset the increased price of the split core format.
These are very compact and economical for their level of accuracy (0.1% which just a few watts). They have 30,075 internal turns, creating a 26.6 mA output at max. amperage.
The CTs will fit on up to ~2000 MCM insulated wires. It is a good idea to measure your wires before selecting a CT model to be sure that they will fit.
- Use 1 CT for 120 volt single phase North American, or 230 volt 2-wire foreign systems
- Use 2 CTs for 120/240 volt single phase systems
- Use 2 CTs for 3-phase 3-wire systems (no neutral)
- Use 3 CTs for 3-phase 4-wire systems
Each CT has a unique serial number, is individually tested, and indicates the correct orientation of the CT in relation to the load of the electrical system being metered.
