However, if the leaves of the iron core have not gotten enough lacquer through them, they WILL buzz a bit. It should not be a problem...just an annoyance. **Q: The picture shows 2 units for $14.99. Do you get 1 or 2 for that price?** A: You will get 2 for the price. **Q: Is the burden resistor required to be added before clamping the connection to the "mains" wire ?** A: No, these are parasitic coils with no “connection” to the mains wire whose current is being measured. You will need to use a known burden resistor to enable measuring the output current. Be sure your expected peak current is well within the specs. --- ## 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/80263074-sct-013-000-non-invasive-ac-current-sensor-split-core](https://www.desertcart.co.uk/products/80263074-sct-013-000-non-invasive-ac-current-sensor-split-core) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-24*
