Now if we double that voltage to 24 volts and power our 100 watt device, than the wire size can be a#10 wire now.
And with 48 volts, it can be a # 14 wire.
What about 120 volt DC? # 18 size wire with our example and you can power many 120 volt ' ac ' devices with that DC power like your vacuum cleaner, circular saw, Incandescent bulb, corded drill with no speed control, electric heater or toaster with no electronic control. etc etc,
