120 to 240v
I just got a tool, a pet clipper. Not realy wood work but a small electric tool. The clipper turns out to be 120v, what happens if I plug it in to 240v?

Consider a small step down transformer which converts 240/250 to 120 volts.
Check the label on your clipper to ensure that it is less than about 100 watts.
Chose a transformer type before an electronic type; a little more robust.
Transformer units can work satisfactorily in reverse, tho plug adaptors may be required.
You may already have one?
Jaycar and Korjo (Travel) have them, but at $49ca, a little expensive, but type approved for Australian use.
Ebay has some new ex Honkers at approx $20 incl post.
Should I mention bending the pins? No
Should I mention Australian type approval; might not.
After any use, keep an eye on the temperature rise of the case, as cheaper type transformers minimise the necessary iron laminations and copper to keep costs down.
Dont let the dogs pee on it.

Those devices usually consist of a magnet jogging back and forth at 50 Hz inside a coil. If the coil is electrically and thermally robust enough to handle the higher V (means greater current) it will just get warmer than usual and could work for quite a while. OTOH the insulation of the wire in coil could also eventually catch fire. The other thing a higher V would do is drive the magnet (and attached clipper blade) harder up against the end stops than usual so I'd expect some form of premature mechanical failure.
Either way I would not use it on 240V

Sounds like the dog is the electrical savvy one here.

Thanks for all the info. The dogs may be smarter than me that is for sure.
