How can one identify 220 volt appliance besides looking on the appliance?
Does 220 volt devices have the same 3 prong (with ground) or two prong configuration on the plug or does something look different indicating that it is 220 volts?
Lastly, I know on 20 amp appliances the plug has one prong going sideways, can there be 120 volt devices w/ 20 amp or is all 20 amp devices 220 volt?
Thanks in advance,
Harvey
