get a 1.5kV tranny. who wants to lug a 3.3 all over the place.
...Not a problem,for a man who collects anvils...
Yep,a 1.5 would be a better bet. The problem with thinking that domestic only,means 230V,is you will end up with extension leads,then you may be working next to other trades,then the customers children come home to "check" how you're doing...for the sake of a couple of plugging moves,risks are reduced.
Sooner or later,you will be working at a customers property,with a 15th Wylex DB,and if the cordless isn't up to it,you may be up a ladder,drilling away,your lead trailing round the garden,when the neighbours kids decide to try skipping,with the new blue rope...
