The cable can't produce excessive voltage - your house will have one mains voltage, so using a 250V cable instead of a 230V one will be fine. As *j* rightly points out, the fuse in the cable must have the correct rating - if your kettle draws (say) 10 amps, but your computer cable has a 3 amp fuse, then you'll blow the fuse when you switch on

2. Yes, you can use them, The amp rating does not change. A 1V power supply that can deliver 25A will blow a 20A fuse if shorted (a 25A fuse would probably glow (light up)). The 250V rating means that they are safe to use in 250V circuit, but may arc at higher voltages. Share.

You use a one phase motor because you don't have three phases. That means using phase-phase voltage on it wouldn't make sense, you should be using a three phase motor instead. The 120V vs. 240V is not related to phase to phase voltage(or live wire to live wire) as that would be \$120\sqrt(3)\approx 207V\$.

Normally it is written on the plug, device or stated in the manual. Most devices can handle both ranges (it will be stated as a range, e.g. 110-250V (AC), if it is usable for 220-250V you can assume the frequency is not a problem for Europe neither, and same for 110VAC elsewhere. This is a disguised good question.

Using transformers helps you decrease the capacity and vice versa. With the North American single-voltage device, its power is from 110V to 125V. The countries having a power supply ~ 230V require equipping a step-down transformer. Keep in mind, the wattage rating of your device must be smaller than the rating of a transformer when plugging in.
Yes, you can connect your laptop charger to an electrical outlet in Rwanda as long as the outlet is compatible with the charger's voltage and plug type. In Rwanda, the standard voltage is 230V and the standard frequency is 50Hz. Most laptop chargers are designed to be compatible with a range of voltages (dual voltage), so they should work with
I bought a Grundfos 10GPM 115v pump (3 wire +ground) and a control box from two separate online vendors, and the control box was a 230v control box (with the 1/2 hp rating that my well pump has). I only paid attention to the HP rating when I ordered the control box, as the model number is very similar for the two Grundfos 1/2 hp control boxes
