I don't know any place in the US or Canada that won't allow you to work on an appliance that is plugged in.  Maybe some places won't allow you to work on hard wired appliances but even then I think that's only if you have to modify the wiring going into it.  Usually the issue is something like replacing an old furnace with a new one and having to bring the whole thing up to current code in the process.  The old stuff can stay adherent to the code from when it was installed but if you update the appliance you have to update the whole setup related to the appliance.

Sure you can.  It voids the warranty of the device in most cases, but that isn't the same as being illegal.

If a permit is required, and the permit can only be pulled by a licensed <whatever>, it would be illegal to DIY.  I'm pretty sure that's the case in RI for a lot of things.  Then again the permit process in RI is more like sliding an envelope under the table than filling out an application.  RI has put more elected officials in jail for corruption than I even want to think about.  It's a vicious circle.

I've personally never run into that issue because I never gotten a permit over work that is not *cough* publicly visible *cough* *cough*.  ;)

Ah, ok so it is about the difference in voltage. 240V sure as hell can kill you! I've been zapped with 110V plenny of times since when I was an apprentice auto electrician we had a 110V step down transformer for testing armature windings. Vigo, the only danger of a car battery is if you drop it on your foot  ;)

When you guys are talking of doubling voltage for heavier appliances in the US, are you talking about 3 phase, because here it gets REALLY scary- 415V  :o  I wonder if in the early days the higher voltages we have here and in Europe/Uk was to do with keeping voltage drop down?

Anyway, here's another question for you, and why I'm surprised it's legal to fool around with mains wiring state-side. No matter what the voltage, the wattage will be much the same for similar appliances. Therefore, as far as I can tell, there is just as much risk of an electrical fire over your way as here. Where do you stand if there is an electrical fire caused by amateur wiring over there? Here, your insurance company will tell you it sucks to be you. Do they not mind over there?

edit: from wiki-


--- Quote ---A 230 V distribution system will use less conductor material to deliver a given amount of power because the current, and consequently the resistive loss, is lower than for a 120 V system. While large heating appliances can use smaller conductors at 230 V for the same output rating, few household appliances use anything like the full capacity of the outlet to which they are connected.
