When I tried these electrical insulated terminals, I was impressed with their durability and ease of use. They are perfect for industrial and scientific applications as they securely hold wiring in place and provide excellent insulation .The terminals are also color-coded, making it easy to identify which wire is connected to each terminal. The only downside is that they are slightly expensive compared to other terminals on the market. Overall, I highly recommend these to anyone looking for a reliable and high-quality electrical terminal..
