Why would any one be as stupid to do this? In saying this, i mean this is an idiot question!!
You wouldn't believe the stupid things people do!.
For an example:
Pace Electronics used to manufacture an analogue satellite receiver, called the MSS1000 - it included a Dolby Pro-Logic decoder and amplifiers internally. The speaker connections on the back used the standard push spring connectors that amplifiers usually use, and the mains lead was the normal 'figure 8' plug in lead.
The customer brought the unit in for repair, I repaired it, and he later collected it. The next day he brought it back saying it didn't work!.
What he had done was cut off the moulded 'figure 8' mains plug, strip the wires, and connect them into one of the speaker sockets - 240V directly into the speaker output of an amplifier!.
As you can imagine, the amplifier didn't like this at all, and he ended up paying for a new amplifier/decoder PCB.
BTW, the gentleman in question is a highly paid advertising executive, this was at his country home, he also has a home in London as well, and perhaps others - I only know of these two.
Connecting a transformer backwards seems fairly 'normal', we probably wouldn't even laugh about it :lol:
