Developed specifically for radon mitigation fans, this compact unit can be used to power ANY radon fan rated at 100 watts or less. The Class 3 Power Supply is a device that plugs into a standard household electrical outlet to create a safe power source for your radon fan. The circuitry in the Power Supply limits the output to 100 watts, and I’ll explain the significance of that wattage in a moment.
First of all, what is the benefits of using a Class 3 Power Supply? Well, simply put, this device allows you to install an OUTDOOR radon fan powered by an INDOOR outlet without any wiring whatsoever! All the connections are plug-and-play for quick, easy activation. How is this possible without violating any electrical codes? The key factor that allows a radon system to be fully plug-and-play is identified in the National Electric Code, Article 725. This code allows both low voltage and POWER-LIMITED 120-volt circuits to use ALTERNATIVE WIRING METHODS.
NEC requires most circuits to be wired using Romex and junction boxes. In most states, this can only be done by a licensed electrician. However, POWER-LIMITED CIRCUITS RATED AT 100 WATTS OR LESS, can be connected using Class 3 flexible cables with molded-on connectors. Class 3 power-limited circuits can operate at up to 150 volts, so most traditional radon fans can be used in a Class 3 Circuit, provided they draw 100 watts or less. Essentially, Class 3 codes allow standard voltage radon fans to be connected using the same method as low voltage radon fans… 100% plug-and-play!
Another benefit of the Class 3 Power Supply is the speed control dial. You can either run the fan at full speed, or dial it down to improve efficiency when full power is not necessary.
