  1. There is nothing wrong with US/Canadian receptacles.

  2. Of course, those are minimum requirements. There's nothing stopping anyone from installing GFCI protection on every single receptacle in the entire home.

  3. Yes they are!

  4. That's BS. GFCIs don't need or care about a ground connection and are not "less effective" without one. That's like saying your speedometer in your car is "less effective" without a passenger.

  5. FYI Nominal voltages: Europe: 230–240V US/Canada: 120V Japan: 100V

  6. I'm pretty sure Japanese plug blades are just a slightly different size than the US/Canada's.

  7.  @BuzzinsPetRock78  Most residential and light commercial panels in the USA are wired to provide 120 or 240 volts. There are two live buses, and two sets of circuit breakers. Circuit breakers lock into slots that connect to the busses that go down the middle of the panel. Each circuit breaker slot alternates the buss as you go down the panel. Circuit breaker dimensions vary by manufacturer (and sometimes amperage rating) but most are around 19×76 mm or 25×82 mm. Most circuits which get fed 120V take power from one buss and return to the neutral. Bigger circuits which need 240V take power from both busses, which is the entire secondary of the distribution transformer. Circuit breakers providing GFCI or AFCI protection are the same sizes as regular breakers, they just need the neutral connection to go through them which normal breakers do not need. Required GFCI protection can be provided by the circuit breaker, the receptacle itself, or a GFCI device upstream on the circuit. (Any receptacles wired behind a GFCI share that GFCI's protection.)

  8.  @tirkentube  Indicator lights on GFCI receptacles vary widely, and are only common on the most recent models. Most older GFCIs do not have them at all. In the past 20 or so years they've gotten more and more popular as a feature selling point. Some light up when the receptacle is energized. Some light up when it's tripped. Some light up when they fail their automatic periodic self test. These all would have only one color of indicator. Some other models have multiple colors for different situations. The manufacturer's installation and operating instructions are the absolute reference for how whatever model you have in your home works. The manufacturer should be listed on the front of the receptacle somewhere, either in the face you can readily see or after removing the cover and examining the usually-covered plastic or metal mounting yoke. Once you identify the manufacturer, you can locate the instructions online.

  9. Earthing rod, ground rod, same thing; earth wire, ground wire, same thing.
