This 3 prong 30 amp 220 volt converter will plug into most electric dryer plug and commercial coffee machine outlets (building built before 1997) and converts the power into 2 separate 20+ amp 110 volt outlets. Even if your own an extractor with built in green light circuit locator, will still light up and give you the 'OK' signal. Sorry, no room in this device for safety ground fault interruption and overload protection.
