Review: Trusted brand - I use Ideal brand wire nuts because I know what I’ll get when grabbing blue, yellow, grey or red ones from my bins. Size of the spiral wire inserts vary across brands so you don’t always know if the size you’re reaching for will be as expected based solely on color and shape. There are usually multiple sizes that work for a given wire combo connection, but there’s always an optimum size so I carry all of them since I connect a variety of wires doing HVAC work. These blue ones are perfect for 2 18 gauge low voltage, stranded wires . The grey ones will work but are a little short. The orange ones work but the extra size can mean the bundle of wires are too tightly crammed into an enclosure. Depending on the specific connection I like having choices handy and the quality has been consistent over the years. Review: Great! - These are just a bit more expensive than the no name ones, but once you have to remove a wirenut and the threads stay on the wires, you will never buy the no name nuts again. ## Features - Positive-grip design requires no pre-twisting for fast, easy installation - Use on bare copper wire do not use with aluminum - Tough UL 94V-2 flame-retardant shell rated at 221 F (105 Celsius) - Rated to 300-Volt max - Fixed, square-wire springs create their own threads to maintain a secure positive grip that will not relax over time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00O9MFTFQ | | Best Sellers Rank | #170,578 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #795 in Electrical Wire | | Date First Available | October 8, 2014 | | Is Discontinued By Manufacturer | No | | Item Weight | 2.88 ounces | | Item model number | 30-172P | | Manufacturer | IDEAL INDUSTRIES | | Product Dimensions | 7.3 x 4.8 x 1.5 inches | ## Product Details - **Color:** Blue - **Connector Type:** Twist-on - **Contact Material:** Metal - **Insulation Material:** Polycarbonate - **Terminal:** Twist ## Images ![Ideal Electrical Wire-Nut® (30-172P) Wire Connector, Model 72B® Blue, 100/Bag - Image 1](https://m.media-amazon.com/images/I/61vlh179ghL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Trusted brand *by D***0 on April 14, 2024* I use Ideal brand wire nuts because I know what I’ll get when grabbing blue, yellow, grey or red ones from my bins.
