High-Current Applications (Maximum Current 100A): External current transformers (CTs) must be used. The electrical meter measures high current indirectly via CTs. Typical Applications:Residential energy monitoringSmall business power trackingElectrical sub-meteringLoad management systems Compliance Information: This DIN-rail Kilowatt Hour kwh Meter is designed for AC circuits only.It is recommended that the kilowatt meter be installed in the electric meter box.Professional installation recommendedFor optimal performance and safety, we recommend installation by a qualified electrician professional installation.

Review: Marvelous - so far I like it , does the job I needed it for , Logging my volts or watts used per incident or daily .
Review: accurate and very easy to install - seems to work ok, i have it set up in my rental unit and as far as i can tell by measuring power use for the water heater, it seems accurate. weirdly there are no electrical connections to it, you simple pass the 2 live wires through the tunnel in the unit and that's it, so very easy to work with.

## Questions & Answers

**Q: is there an optically isolated pulse output available at termnals 5 and 6?  is this what the two gray connectors under the cover are for?**
A: Yes

**Q: I have a 2 stranded aluminum from box goingto camper will this work**
A: I use it on mine

**Q: L1 and l2 are 110v. will it measure both lines**
A: This is Single Phase Three Wire ,measure both lines L1,L2.
 L1,L2 works through meter which is 220v, N have not work through meter.
L1-N =110V, L2-N=110V, L1-L2=220V
This meter will not work on a single phase 120v 2-wire system.

**Q: Have an apt fed by 100amp double breaker in house panel. can i mount this next panel with pigtails to meter? apt feed is 240v. two hots and a neutral**
A: Yes. All you need are two hots and two small jumper wires as per the instructions. Then hook up whatever you wish to monitor as per the instructions. Its simple and easy. No neutral wire needed.
