More information
CT Type: Split-Core
Max. Amperage: 200 amps
Inside Diameter: 15 mm or 0.6 inches
Outside Diameter: 45.5 mm or 1.75 inches
Thickness: 18.5 mm or 0.75 inches
Model: ESCT-015-200UL
Certifications: Approved by UL for use with our UL Listed Omnimeters
Wire Gauge: For use on wire that is 1/0 size 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.
These 15mm 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 200 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 7518 internal turns, creating a 26.6 mA output at max. amperage.
The CTs will fit on up to 400 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
These CTs are UL and cUL Recognized and are approved for use with our UL listed meters, to be a complete UL Listed meter install.
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.

Multiple units sharing a meter from another unit best way to pay for use except on thr demand part of time of use
The CTs work perfectly.
I recommend an assortment of locking bushings be included to clamp the CTs securely against the primary cable to prevent the CT falling against other components. I used cut 1/2" and 3/4" bushing with zip-ties to do this, but a designed product might work better.
This compact system worked as advertised right out of the box.
I did have to tell McAfee to get lost, as it thought that this SW was a virus pit.
G-Data likes the software just fine :)
My application is for load shedding. That is, real-time monitoring of the current load on the incoming service lines, with relay control to disconnect loads that are basically optional (e.g. disconnect the EV charger).
Software downloaded easily and immediately began communication with
the meter over a 42' twisted-pair RS-485 link to the Dash software program.
Data export to Excel is straightforward.
I did have to use a Dremel tool to very lightly trim the CT's to fit around the
main lines into the Service Entrance. That said, I definitely appreciate the
compactness of the CT's they use ( mine are CT-200's )
My only complaint at this point is that I cannot arbitrarily set the beginning and ending temporal points for data export. Seems to be all or nothing.
Great equipment and easy installation. The youtube video was spot on. Thanks for a great product.
Why does your diagram show only using two CT’s for metering a 3 phase panel and jumping from 8 to 10 on your diagram
If you are using an EKM Omnimeter to meter a 3-phase 3-wire system, you only need to use 2 current transformers. Here is a page that describes how to meter this system: https://help.ekmmetering.com/support/solutions/articles/6000081678-3-phase-3-wire-metering-up-to-600-volts
The reason you only need 2 Current Transformers for a 3-phase 3-wire system has to do with what is called "Blondel's theorem”:
http://en.wikipedia.org/wiki/Blondel's_theorem
This essentially says that the number of CTs you need to use to meter a given system is the number of hot wires plus the neutral wire, minus 1.
# of CTs = # hot wires + 1 if there is a neutral -1
Therefore if you have 2 wires: you only need 1 CT, 3 wires: you only need 2 CTs, 4 wires: you need 3 CTs.
Does it come with a digital read out?
Our current transformers are meant to be paired with our EKM Omnimeters. If you were to only buy this ESCT-015-200UL CT it would not come with anything else, so would not be useful by itself in most cases. The CTs and the Omnimeters are sold separately.
You will need either 1, 2, or 3 CTs per Omnimeter depending on your electrical system:
- Use 1 CT for 120 volt 2-wire systems (or foreign 230 volt 2-wire systems).
- Use 2 CTs for a 120/240V three-wire system (two hots and a neutral, with or without ground).
- Use 2 CTs for 3-phase 3-wire systems.
- Use 3 CTs for 3-phase 4-wire systems.
Hi, is this current sensor IP65 or higher rated. Can it be used for outdoors? Thanks
No, this CT model is not IP65 rated and is not suitable for outdoor use. For an outdoor CT model I recommend our OSCT-063x033-800 (https://www.ekmmetering.com/collections/current-transformers-cts/products/outdoor-split-core-ct-800a), which is IP65 rated and will work on electrical systems that are 800A or less.
Thank You!
