- I moved to Canada from the UK in '81. The power here is normally 110V 60Hz.
- Single-family houses are fed with two 180degree phases of 110V, plus ground
- (earth) plus neutral. The lights all run off one or other of the 110V phases.
- Electric heating, clothes dryer and range (cooker) all run off 220V. Most
- electrical outlets come in pairs. The outlet pairs in the kitchen are made to
- run off different phases - don't ask me why, I think the idea is that one is
- likely to plug a kettle and toaster into the same outlet pair and they should
- not be on the same circuit breaker (typically 16A).
- In some apartment buildings I think that there is 208V 3-phase instead of
- 220V - I'm not so clear on this, not having lived in one.
-
- For small stuff, you can use a transformer or autotransformer. It's still
- 60Hz though. Transformer get heavy and expensive really quickly; 50W is no
- big deal.
-
- I got a 60Hz rotor for a record player, and run it with a
- transformer. I have a British-bought dishwasher and washing machine, and run
- them on 220V with no problems. Before I moved I wrote to the manufacturers
- for advice, and got replies ranging from "Go for it" to "It'll never work,
- the widgets will melt, you'll all be doomed, etc.". In view of the absurdly
- low resale value of my relatively new appliances, I went for it.
- I presume that the time-dependant portions of
- their cycle run 20% fast, but a lot of it is state-dependant (fill till a
- certain level, heat till a certain temperature, etc.) I also run a British
- iron, boiling jug and blender. For an electonic alarm clock I was fond of I
- rewound the transformer and grounded a frequency-select pin on the chip. I
- also have a British B&W TV that I used to use with a computer, currently
- serving time as a video monitor after adjusting the vertical height (I could
- pick up pictures from a couple of TV stations, but the sound carrier is
- different).

-
- Haven't seen any. I converted one light fitting by simply substituting a
- screw-type receptacle for the bayonet one.
