Review: Great quality wire at a good price. - Great quality solid core wire at a good price. Better price than a home store. Can be used for low-voltage applications such as thermostat wiring, doorbell systems (hence the name 'bell wire'), security systems, and some speaker (short runs) and LED lighting applications. Ensure the wire's ampacity (current-carrying capacity) is sufficient for the connected devices. At 60°C (140°F), it's 14 amps; at 75°C (167°F), it's 18 amps; and at 90°C (194°F), it's 22 amps. I used this with a 16 volt transformer to power a Ring brand doorbell. Works great, no issues with tangles while unraveling and pulls well through walls. Bought a lot so I can wire thermostats as well.
Review: flexible, sturdy, and easy to strip - Absolutely perfect for my thermostat wiring project! I needed to run a new wire from my heat pump to the thermostat to be able to use my smart thermostat (c wire; if you're familiar with it). The 50-foot length gave me plenty of reach, and the red/white color coding made connections simple. The 18/2 gauge is just right for this purpose; it's flexible but sturdy, with clean insulation that strips easily. If you're running doorbells, thermostats, or DIY security sensors, this wire delivers solid performance and value. I strongly recommend!
