Review on Enhanced Cooling Solution: PartsSquare 185-200 Degree Electric 🌡️ Fan Thermostat Sensor Temperature Switch with 50 Amp Relay Kit by Jermall Meredith

The wire diameter is too small to support even a 30A fan. The relay also appears light and thin. Like I bought it on eBay. If you run 30 amps or more through this wire, it will melt and cause a fire. I like that it includes a 30 amp switch instead of the 50 amp switch it should be designed for. The starting current is different than the running current, but you'll still be very low if you look at a fan that can run 30, again it's supposedly rated at 50 amps.
