Re: Wire my Garage like a Boat?
DC is not necessarily safer then AC. It's one of the reasons Edison's AC push won over Tesla's DC push for power back in it's infancy. Sure if you are just using low voltage wiring and lights it is safe. But as soon as you put an inverter on it amp up the voltage it is not. You now have enough voltage to push the electricity through you. And it is ungrounded.
If you use an Inverter you just changed to AC. If you ever used an Arc welder you would see the difference between DC straight, DC reverse an AC. In most cases when you switch DC to AC you lower the amps because AC runs hotter. Edison won because it takes less amps or power to turn the lights on.
