ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Rated voltages in the USA?

also i will add here about usa voltage on single phase is 120/208 that is off from the three phase network and few home and alot of large apartments use that voltage and it is very common to find it in commercal appcation my shop have mixed bag of voltages both single and three phase whatever you got it i have it in my shop from 120 all way to 600 ( the 600 volts is kicked up with transfomer NOT autotransfomer!) and most 240 volts single phase plugs can use on 208 volts also but somehow it will be marked down to beaware of 208 system and to find 208 appliances of course they do make it and alot of heating equempent do run on 208 and few other stuff it kinda pretty long list to type for me but a quick point here about 240 and 208 volts single phase they are line to line not line to nuetural just let you know about that and i am not talking about delta at all in case this is single phase from three phase wye system
