Our country's voltage setting is 220 V, but I have a bunch of devices that are rated 110V (surplus coffeemakers from Japan to the awesome Philips Hue smart bulbs).
So I was thinking of adding a 110 V source throughout my apartment. Would this be easy? Would it be costly?
I read somewhere that all I had to do to step down "cheaply" is ground one of the 2 LIVE wires, instead of hooking up a massive transformer for the lot.
Is this safe, logical, recommended?
What if I'm on the higher floors, and the building doesn't have "grounds" (our country doesn't use grounding, so 3 prong plugs need to be converted to 2 prong)?
