I saw this meter used in an other application where it will get either 120V or 240V and it is actually spec'ed to work that way: http://www.ekmmetering.com/ekm-omnimeter-i-v-3-universal-smart-meter-sin gle-phase-or-3-phase-120-to-480v-50-60hz-up-to-5000-amps.html Note that it does require a single Current Transformer and it has insulated signals for pulse (metering) or serial communication. It is not cheap but does the job well. Another variant of this meter is used in the new JuiceBox versions. They use the UL approved version of this meter.

Where did you read that the meter does not work for 120VAC? The description for this meter: http://www.ekmmetering.com/120-240v-package.html says: "This metering package includes everything you need to meter 120/240v electrical systems and to send your meter data to the cloud." And it has piercing connectors for neutral as well as the two hot leads. Seems it should work. I have an EKM that is 5 years old and it works similar to yours - doesn't record on 120VAC - but it does not have the separate current transformers nor pierced neutral that the above meter has. I would email or call EKM to check. Not recording on 120VAC is not a problem for me since I never use 120VAC. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/120-240Vac- Watt-Hour-Meter-tp4672842p4672857.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
