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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Recomendado 100% *by J***A on June 6, 2026* Perfecto. Tal como lo explican. ### ⭐⭐⭐⭐⭐ Marvelous *by J***N on September 13, 2025* so far I like it , does the job I needed it for , Logging my volts or watts used per incident or daily . ### ⭐⭐ Received DOA *by S***E on February 16, 2021* Does not register any current usage. I hooked this up to a 110v blow dryer for 30 minutes and it didn't register any power consumption. It was connected properly. Note: I purchased the digital version of this same unit and it is working well. ## Frequently Bought Together - Baomain DDS238-4-R DIN-Rail Single Phase Three Wire Energy Meter 110V 220V 60Hz 10 (100) A - LMioEtool ABS Plastic Dustproof Waterproof IP65 Junction Box Hinged Shell Universal Electrical Project Enclosure Gray, with PC Transparent Clear Cover 8.7 x 6.7 x 4.3inch(220 x170 x110mm) - 1 Piece DIN Rail Slotted Aluminum RoHS 12" Inches Long 35mm Wide 7.5mm High --- ## 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.ro/products/54374208-baomain-single-phase-3-wire-din-rail-kwh-meter-110v](https://www.desertcart.ro/products/54374208-baomain-single-phase-3-wire-din-rail-kwh-meter-110v) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-22*
