Yes you can do this with 2 hots and no neutral. Wire it this way: With the Omnimeter you will use only 1 CT and not 2, since you have 2 hots (Line1 and Line2) and no neutral. Connect CT1 into terminals 1 and 2, and run Line1 through CT1. Tap off of Line1 wherever is convenient and connect this voltage reference wire to terminal 7 (L1) on the meter. Tap off of Line2 wherever is convenient and connect this wire to terminal 10 (N) on the meter. That's it and you are good to go. We do recommend 1A fuses on L1 and L2. Thanks. Seth, EKM Metering **Q: what size wires/how many wires will pass through the donuts? I want to meter about 4 separate 20 amp circuits.** A: Thanks for your inquiry. We carry many different sizes of Current Transformer "donuts" to accommodate different sizes and amperages. These are all sold separately: https://www.ekmmetering.com/collections/current-transformers-cts If you want to have multiple individual readings for multiple individual circuits then you will need separate meters for each. However, if you want a total reading for all the circuits combined you can use one meter and run all the hot wires (from the same phase/source/leg/etc.) through their own CT - just make sure the diameter of the CT hole is large enough to accommodate your wires. Alternatively you can use separate CTs for each hot line and combine them into the same ports on the meter. Here is how you can pass multiple wires from the same phase through a current transformer: https://help.ekmmetering.com/support/solutions/articles/6000131301-can-i-pass-multiple-wires-through-a-current-transformer- And here is how you can use multiple current transformers on the same phase: https://help.ekmmetering.com/support/solutions/articles/6000131304-can-i-use-multiple-current-transformers-on-the-same-phase- More info you will need to know about this meter and its options: https://help.ekmmetering.com/support/solutions/articles/6000067374-ekm-omnimeter-i-v-3 Best regards, Seth EKM Metering Inc. www.ekmmetering.com www.encompass.io **Q: Does this unit ever have to be calibrated to keep it's accuracy?** A: To my knowledge, no, it does not have to be recalibrated. We been using these meters for 3 or 4 years and have not had any call backs for a single unit that we've installed. **Q: I have a subpanel box that i need to monitor. i bought the ekm 251ds, but it wouldn't work because its a 200 amp box. do you have anything for 200amps** A: The omnimeter pulse v4 should do the job. It is advertised to handle up to 5000 amps. Be sure to get pickups large enough for your 2-0 or 3-0 wire. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I love that it logs data to the EKM Push Device *by B***S on February 15, 2017* I have used it on voltages from 120vac to 460vac.

I am very impressed with this meter and the it has collected has been very beneficial to my business. ### ⭐⭐⭐⭐⭐ Reliable *by F***K on July 11, 2023* These meters continue working, even when disconnected from the Internet. ### ⭐ customer service is atrocious *by S***R on September 21, 2020* Being a licensed plumbing contractor I went to the website to obtain information to professionally install their submeters purchased by one of my customers. For several months after that I was deluged with multiple daily emails designed to get my attention. There was no way to unsubscribe. When I finally reached out to customer service to ask them to stop the emails I was accused of spamming them! If customer service is that rude I will never do business and encourage everyone who reads this to be cautious as well. ## Frequently Bought Together - Universal Electric kWh Meter - Omnimeter I v.3 - EKM Metering -- Indoor Enclosure Kit - EKM Metering Current Transformer - 15mm, 200A, 200A:26.6mA, Solid Core CT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/9686668-ekm-omnimeter-i-v-3](https://www.desertcart.co.uk/products/9686668-ekm-omnimeter-i-v-3) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-05-02*
