Review: Great item! - These are great for homes that have old aluminum wiring. The twister have penatrox inside, so no mess! Review: Safety is priority - This gets it done - For those who have electrical that is outdated (Aluminum), this product comes to the rescue. For the value, it is well built, seems durable, as some existing wiring before we purchased our home had these wire nuts installed, which means they last a long time. It was really easy to use across my home for the wiring that wasn't pigtailed with copper, and now I can breathe easy knowing that my wiring is safe in my home. One note, ensure that you don't have excess copper when pigtailing at the end, same as aluminum, or else the wire nut will not work and fail to twist. ## Features - AL/CU CONNECTIONS: Supports aluminum-to-copper and copper-to-copper applications from #18 to #10 AWG wire β€” do not use on aluminum-to-aluminum connections - RETROFIT APPLICATIONS: Perfect for retrofitting older residential buildings with this one-time use connector - CORROSION RESISTANCE: Prevents oxidation of aluminum conductors with pre-filled antioxidant compound - PROTECTIVE SKIRT: Extended opening keeps the antioxidant compound inside while increasing dielectric strength - SECURE CONNECTIONS: UL-Listed to 486C and CSA-Certified to C22.2 #188 for aluminum-to-copper connections up to 600V, as well as the only twist-on solution to comply with NEC Section #110-14 (b) - HIGH-LEVERAGE WINGS: Engineered for twisting action with comfortable wings, reducing your hand strain - LIVE-ACTION SPRING: Installs smoothly with a spring that expands and contracts with the aluminum wiring, delivering superior hold strength and quick take-up - IMPACT STRENGTH: Durable copolymer shell withstands grabbing and pulling from tools - PACKAGE INCLUDES: Bag of 10 Twister Al/Cu electrical wire connectors ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071RTSRGD | | Best Sellers Rank | #44,121 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #259 in Electrical Wire | | Brand Name | Ideal Industries | | Color | Purple | | Connector Gender | Male | | Connector Type | Twist | | Contact Material | Aluminum | | Customer Reviews | 4.6 out of 5 stars 330 Reviews | | Included Components | Connector | | Insulation Material | Polycarbonate | | Insulation Material Type | Polycarbonate | | Item Dimensions L x W x H | 0.8"L x 0.65"W x 1.34"H | | Item Weight | 9.07 g | | Manufacturer | IDEAL INDUSTRIES | | Material | Aluminum | | Material Type | Aluminum | | Maximum Voltage | 94 volts | | Model | 30-1765S | | Number of Items | 10 | | Part Number | 30-1765S | | Stud Size | #10 | | Temperature Rating | 221 degrees_fahrenheit | | Terminal | Twist-on | | UPC | 783250739868 | | Unit Count | 10 Count | | Warranty Description | See www.idealind.com or call Customer Assistance for warranty details. | ## Product Details - **Color:** Purple - **Connector Type:** Twist - **Contact Material:** Aluminum - **Insulation Material:** Polycarbonate - **Terminal:** Twist-on ## Images ![Ideal Electrical Twister Al/Cu Wire Connector, 30-1765S, Bag of 10 - Image 1](https://m.media-amazon.com/images/I/61GNB3kpmZL.jpg) ![Ideal Electrical Twister Al/Cu Wire Connector, 30-1765S, Bag of 10 - Image 2](https://m.media-amazon.com/images/I/61OsIwm5TGL.jpg) ![Ideal Electrical Twister Al/Cu Wire Connector, 30-1765S, Bag of 10 - Image 3](https://m.media-amazon.com/images/I/81wM5oPnXHL.jpg) ![Ideal Electrical Twister Al/Cu Wire Connector, 30-1765S, Bag of 10 - Image 4](https://m.media-amazon.com/images/I/81goGSOa7cL.jpg) ![Ideal Electrical Twister Al/Cu Wire Connector, 30-1765S, Bag of 10 - Image 5](https://m.media-amazon.com/images/I/61T7XzZqLoL.jpg) ## Questions & Answers **Q: Is this 10 sets of two caps?** A: No, item #30-1765s or #30-765 is a package of 10 connectors. 2 packs would be item #30-1065s or #30-065. **Q: What wire size do these wire nuts handle???** A: I use for aluminum wiring connected to light fixtures mainly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great item! *by D***E on December 21, 2025* These are great for homes that have old aluminum wiring. The twister have penatrox inside, so no mess! ### ⭐⭐⭐⭐⭐ Safety is priority - This gets it done *by B***A on May 12, 2026* For those who have electrical that is outdated (Aluminum), this product comes to the rescue. For the value, it is well built, seems durable, as some existing wiring before we purchased our home had these wire nuts installed, which means they last a long time. It was really easy to use across my home for the wiring that wasn't pigtailed with copper, and now I can breathe easy knowing that my wiring is safe in my home. One note, ensure that you don't have excess copper when pigtailing at the end, same as aluminum, or else the wire nut will not work and fail to twist. ### ⭐⭐⭐⭐ ONE TIME USE *by C***Y on March 24, 2026* These wire nuts are for making copper to aluminum connection safe. They work perfectly but just be aware of the fact that the nut can only be used 1 time so make sure all your wire connections are correct before putting the wire nut on. If you make a mistake and then try to use the wire nut a second time the connection will not work and there will be no power. I learned first hand on this so learn from me and don’t try it. These are not cheap connectors but they are the correct connectors for connecting the two different materials. ## Frequently Bought Together - IDEAL Electrical 30-1765S Twister Al/Cu Wire Connector, 65 - Purple, (Pack of 10) - King Innovation 95110 3-Port Aluminum Copper (10-Pack) Wire Connector, Purple --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/100992099-ideal-electrical-twister-al-cu-wire-connector-30-1765s-bag](https://www.desertcart.us/products/100992099-ideal-electrical-twister-al-cu-wire-connector-30-1765s-bag) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-31*
