Wrenches,

Do you design for 110/220 or 120/240 VAC?

>From http://www.seed.slb.com/qa2/FAQView.cfm?ID=427 "120 volts is the nominal "delivery voltage" at the connection point (e.g. the meter) between the utility network and your house. 110 volt is the standard "utilization voltage" for most household appliances in North America. The 10 volt difference is for voltage drops through the interior wiring of the house. In North America, many domestic electrical appliances have a "nominal" voltage of 115 volts with a tolerance of +/-10%."
