I want to buy a quantity of used petrol generators which are 110V CTE (Centre Tapped to Earth), 50Hz, under BS4343 standard arrangement and have an output range of 2.2Kw/2.7Kva to 416.0Kw/7.5Kva with socket configuration of 1x16Amp and 1x32Amp upto 3.5Kw/4.4Kva and 2x16Amp. and 1x32Amp for 4.0Kw/5Kva and up.. The generators are meant for export and are to be used in a country which has a 220V setup. I wonder if a member could suggest how these 110V generators could be converted/configured to operate on 220V. Thanks.

There should be two coils in place. If you meter between outlets, there should be 220 VAC present. I imagine you could alter the internal wiring to eliminate the center tap and apply the two hot leads to an appropriate outlet. As long as the frame is earthed, that should be reasonably safe.

Someone from a country with 220 VAC mains may know more or better about correct practice.
