Ac watts

My Ac is 240 v

Is a 250 v cable safe to use?

what do you mean by this?

 

Cables are just pieces of metal, they are not directly responsible for handling voltages.

Sort of are. Cables have a voltage rating. If you go higher than the printed voltage, the insulation can give in and start melting. This can result in a short and/or a fire. At high voltages, there is also the possibility to start arcing.

 

So to answer - voltage doesn't affect the gauge/size of the wiring, but does affect the insulation.

It's fine. You do need to check the current rating as well to be sure.

that's why I asked what OP meant, since we weren't given any gauge or certification. in the vast majority of cases, any standard 3 prong cable can be used with any PC, which is what I think was being asked about, but I don't know what kind of device is in question.

Yes.

240\250V are volts, not watts. And even if your cable is rated at different voltage, if it's still close enough it's fine.
