Many designers do not believe in vector-less IR-drop analysis, which is inherently a guess plus some margin. Many low-power designs are using power (or ground) switches to implement power shut-off. These switches represent resistance in series with that of the power grid. the imagination station toledo ohio

VA is Volts x amperes. Choose highest VA. 250 volt switch at 1 ampere is 250 x 1 = 250 VA or 125 volt at 3 amperes = 375 VA. 375 VA becomes the maximum rating. 250 volts is the highest voltage 3 amps is the highest amperage. RULES: 1. do not exceed VA as calculated.
