Review: They must know how to use it properly - It works great Review: It Works as stated. - I am currently using the 3pole version of this switch. So far it works perfectly in switching between generator and utility power. I was very impressed with the speed of the switch over when utility power was restored,so much so that there was not even a pause on the TV I was watching at the time or even the internet router. It was a very smooth operation. I am only giving 4 stars because I have only just started using this switch,so cannot rate durability but I look forward to using it for a long time in a domestic home situation. Would recommend it for an affordable transfer switch option.Unless you are a trained electrician please have it professionally installed. ## Features - Operating Voltage:220V.
