To simplify the ordering process, we have bundled together our individual products into a complete metering and data package for your 3-Phase 4-Wire (3 hot and 1 neutral) electrical system. The products are separated into two categories: Required and Recommended.
How to Set Up and Order a Metering Package:
Required Items for a 3-Phase 4-Wire Metering System:
1x EKM Omnimeter: These are our universal kWh meters that are capable of accurately and reliably metering any electrical system in the world. They are perfect for your 3-Phase 4-Wire electrical system (sometimes called 3 Phase WYE (Y)).
3x Current Transformers: The Current Transformers (CTs) are the little donut shaped devices that go around the hot wires being read. For a 3-Phase 4-Wire system, the meter will not function properly without THREE of these. To determine the CTs that are right for you, you will need to know the maximum amperage of your system and the wire outside diameter.
Recommended Items for a 3-Phase 4-Wire Metering System:
1x EKM Push: This is the revolutionary communication gateway and cloud service that makes your meter data easily accessible in the cloud. Simply connect the EKM Push gateway to your meter(s) and internet router. The EKM Push will instantly begin to read your meters and send your meter data to the cloud. There is no setup or configuration needed.
1x EKM Dash: This is our PC, Mac, and Linux software interface for your meter and Push data. The EKM Dash will allow you to monitor and store your meter data on your own computer. You can use it to change meter settings, schedule alerts and emails, export to CSV, and more. This software can be used with an unlimited number of meters. No monthly or annual fees.
1x Meter Enclosure: If you aren't mounting your meter in an existing panel or breaker box, we recommend you mount it in one of our water-tight or indoor enclosures.
1x USB Adapter: This powerful little converter allows you to connect your meter directly to a computer. This is an optional connection (recommended) that may not be necessary depending on your needs but it will allow you to read your meter directly with the EKM Dash, change meter settings, etc.
3x Fuse Holders w/ 1A Fuses: The fuse holder is mounted inline on the hot wires that tap into the main hot lines and run to your meter. They are intended to additionally protect your meter in case of a power surge or some other unforeseen anomaly.
4x Piercing Connectors: These will allow you to easily tap into your hot and neutral wires, and to run wires directly to your meter. These are the wires that power the meter and give it a voltage reference. These Piercing Connectors are optional but they can sometimes make installs easier.
Sticker Label Sheet: Will allow you to clearly label the CTs and all electrical, CT and communications wires.
50ft CAT5 Cable: This wire (used for RS485 communications) contains four twisted pairs of wire. Only one of the twisted pair wires is required for the communications side of the metering. This is the wire that will be used to connect your meter to the EKM Push and/or to the USB Adapter. If there are multiple meters in the system, they can be connected to each other in a daisy chain.
1x Ethernet Cable:: If You are planning to use the EKM Push system, you will need an Ethernet cable to connect the EKM Push box to your internet router.
Additional items you may need from your local electrical supplier:
4x Wires (16-18 AWG): Connect to the main hot and neutral lines and then connect them to your meter. This is most easily done in conjunction with the Piercing Connectors listed above.
Customize your metering package by choosing your products from the drop-down lists and check boxes above. If you would like to order additional products that aren't available in this package, please select them from the appropriate category of the Products Menu.

The Omnimeter in conjunction with the EKM Push system provide rich real-time and historical data. The Widgets below provide a couple examples for how you can view your data.

Questions & AnswersExpand allCollapse allSort byMost Recent QuestionsQ:What is the recommended calibration schedule for this system? How much does it cost to calibrate? Can it be calibrated to ISO 17025 standards?1 answersQ:Would it be possible to use this system on a 120v 1 phase circuit and get accurate readings?1 answersQ:How do you manually read kWh usage every 30 days ? Is there a manual reset or is there a scrolling method on the meter?1 answersQ:Do u have 600 volt three phase meters or can yours be adapted to work with 600v?1 answersQ:What is the accuracy for the metering?1 answersQ:We have a 200amp service coming into our house that serves our home, an apartment that's attached to our home, and a salon in a separate building out back. (I believe the salon has 100amp service and our house and the apartment share the other 100amps.) I would like to separate the amount of electricity used by the apartment and by the salon from what our home uses. So I would basically need 3 separate readings each month in order to separate our electrical bill fairly. How can we accomplish this?1 answersQ:How many three phase loads (CT) can we monitor off of one meter? Each load will have a different amps.1 answersQ:If there is a power outage, would this meter hold/store the information?
Something like a car odometer.1 answersQ:How useful would this system be in setting up a load control system that manages peak demand? Do you sell or other components to compliment your metering system?1 answersQ:Can we monitor 2 separate loads, with 2 separate sets of CT's, but have them feed into 1 meter?1 answersQ:Can you export usage data into excel?
