Only larger workshops have a transformer. It's needed for every workshop in Germany. http://www.reichelt.de/?ACTION=3&GROUPID=3320&ARTICLE=21747&SHOW=1&; http://www.reichelt.de/Labornetzgeraete/PEAKTECH-2240/3//index.html?ACTION=3&GROUPID=4952&ARTICLE=101937&SHOW=1&START=0&OFFSET=16&&gclid=CNPrquyVoLoCFcmV3god3h8Abw Assumed it shouldn't be needed in other countries, it's anyway common that engineers only work on gear connected to the mains by galvanic isolation _in all countries_. You won't spend 50,-€ to save lives ;)? Btw. usually it's an adjustable transformer, because a German workshop needs to be able to transform the 230V to e.g. 120V for gear build for the USA etc..
