Plug in RCD 230V or 110V transformer

Well thanks for the responses, seems that the transformer is the way to go over the RCD. Most of my power tools are corded at 110V. I do like the battery tools but still don't think they are quite there yet compared to battery tools for the bigger consumers such as mitre saws and circular saw. I've literally watched people with the Dewalt flexvolt system get no more than 12 cuts in sheets of ply before the battery is done. Given my work it is easy in most situations to set up my 3.3KVA transformer outside or in a customers garage and if necessary run a 110V extension, though I rarely have to most of my tools have long enough leads on them. The 0.75KVA will be kept closer to power the smaller tools such as the multitool etc. Again I have seen the battery equivalents die after just 20mins of use. 


The reason for asking the above question is that it looks like I'll have to buy a bigger transformer for the intended 2100W router, the 3.3KVA transformer only has 2 16Amp sockets so I need a new one with a 32Amp socket and may as well get a 5.0KVA so can run the router for more than 5-8mins. The router will be the only tool I have that will require the bigger transformer, all my other tools are at or below the continuous rating of the 3.3KVA transformer. That's why I was wondering for just one tool which will not be used on site ever, maybe rarely on a job, but mainly for home projects a 230V tool would suffice.
