3-Phase 4-Wire Metering Package
Price as configured: $0.00
This metering package includes everything you need to meter 3-Phase 4-Wire electrical systems and to send your meter data to the cloud.
Please customize your metering package by choosing the products you wish to order from the drop-down lists and check boxes above.
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 Push3: This is the revolutionary communication gateway and cloud service that makes your meter data easily accessible in the cloud. Simply connect the Push3 gateway to your meter(s) and internet router. The Push3 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.
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.
2x 485Bee Zigbee radio Nodes: Install one on the meter, or string of meters, and one on the EKM Push or USB Converter, in order to establish a wireless connection between the meter(s) and the communication device. Additional 485Bee nodes can be added to strengthen the mesh network.
1x 12V DC Power Supply: This can be used to power a Push3 and/or 485Bee radio. Use a 12V DC Splitter in order to power both devices with a single power supply.
1x 12V DC splitter: Allows you to use a single 12V DC power supply to power two devices, like the EKM Push and 485Bee.
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.
1x Ethernet Cable: If You are planning to use the Push3 system, you will need an Ethernet cable to connect the Push3 gateway to your internet router, if you are not planning to connect via WiFi.
Sticker Label Sheet: Will allow you to clearly label the CTs and all electrical, CT and communications wires.
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.
