In everyday speaking even electricians still refer to 3-phase 400 volt power as "three eighty" (lit. tre ottanta) i.e. the old 380 volt nominal voltage. :) I still see US technical documentation refer to mains as 110VAC...despite the fact it's been at least 115-117 for ... > 50 years. ;) Nominally, it's still generally around 110 to 125. Distribution in the US is a mix of many things, residential is normally standard though at least. ;) Now...the code and breaker panels and outlets however... HTH, G. P.S. I think that the UK may still be on 240/415 actual voltage even if they adhere to the European standards about the unified 230/400 delivery. -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
