I get a signal on scope from tip to ring. What is sleeve for?** A: I think that the extra wire is just a shield and is normally connected to ground. That is good practice but probably not necessary in this case. Be sure you know which wires carry the signal current you can check this with an ohm meter. There will be a measurable resistance between them. Be sure that there is a resistive load across the signal wires before restoring power otherwise a very high voltage will result. Remember this is a current transformer. **Q: Is this switch normally open or closed?** A: This is an AC current transformer--the output voltage (1 volt = 30 amps) is proportional to the current carried by a single wire passing through the core. This item does not contain any switch. If you are measuring current carried by typical Romex cable used in house wiring be sure to pass only one of the 3 wires through the core. The white or black wire should be carrying the same current (but out of phase 180 degrees) while the uninsulated safety ground wire should be carrying zero current. The split core allows the transformer to enclose a wire without disconnecting the wire to thread it through the core. **Q: I have no output from my unit. i have the sensor around the hot lead of a 110vac circuit running a fan and air compressor. is my unit defective?** A: You need a burden resistor. **Q: In the picture it shows it being wired up across two analog inputs. Can you not wire one lead to ground and the other to a single analog input?** A: From one analog input to 'analog ground' will work. For accurate measurements analog and digital grounds should be separated, and tied together near the power supply. ## Frequently Bought Together - JANSANE SCT-013-030 30A Non-invasive AC Current Sensor Split-Core Current Transformer - HiLetgo ADS1115 16 Bit 16 Byte 4 Channel I2C IIC Analog-to-Digital ADC PGA Converter with Programmable Gain Amplifier High Precision ADC Converter Development Board for Arduino Raspberry Pi - Arnorin 3.5mm Stereo Female Terminal Block Panel Mount Connector 2 Pack --- ## 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/91636181-sct-013-030-30a-non-invasive-ac-current-sensor-split](https://www.desertcart.co.uk/products/91636181-sct-013-030-30a-non-invasive-ac-current-sensor-split) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
