Residential Electricity
One might note about the gradual change in distributed voltages in the US. The existing infrastructure has wire which has a given ampacity rating, or to say it has a maximum current limit. Due to increases in power consumption, either V or I could be varied, but with the same wire voltage must be increased. This is why the old "110/220V" basis became "120/240V". It may be increased more in the future for similar reasons.--Billymac00 (talk) 03:44, 4 December 2009 (UTC)
