Wire Gauge: For use on wire that is 10 AWG or smaller.

It is best to measure your wire diameter in millimeters, rather than use the AWG gauge. 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.

Our 7mm Solid Core CT is both economical and very popular with our customers. It is very compact and can measure the current of the majority of residential systems. These CTs are designed to be used in conjunction with our Omnimeter line of kWh meters.

These CTs are extremely accurate down to a few watts. They have 3759 internal turns, creating a 26.6 mA output at full amperage. They are also exceedingly precise at 0.1% accurate. Use these CTs for any system from under 1/4 amp to 100 amps.

  • 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 comes with 72 inch wire leads.

These CTs have received UL Approval for use in combination with our UL listed Omnimeters for a complete UL Listed installation.

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.

These CTs have a very small internal diameter so if you're considering them, be sure that your wire diameter is less that 7mm.
