This 4 prong 30 amp 220 volt conveter will plug into most electric dryer plug and commercial coffee machine outlets (in buildings built after 1997 and mobile homes) and converts the power into 2 seperate 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 interuption and overload protection.
