If that's the case, you're fine. basic plug adapters just pass through the voltage they receive (230 in your case),and the 250V is just telling you the max wall outlet voltage it's rated for. Then as long as whatever device plug you plug into that can handle 240 input, you're good. 250.1 volts is not too high, the supply can be up to 253v before it is judged as too high. Can I plug a 220V into a 250V? If the cord has printed on it “250V” and your mains power is between 220V-240V[1] and the power cable fits into your wall power outlet and into the amplifier, then go ahead and plug it in, you will have no problems. How many power boards / adapters can you plug into a power point before overloading it? You should distinguish between those appliances that draw a high wattage, e.g. electric heaters, fridges, electric jugs, clothes driers etc, from those that draw only a little — e.g. phone chargers, bedside lights, computers, peripherals, small TVs, radios What will happen if I plug a 250V cord into a 220 240V amplifier? If the cord has “250V” printed on it and your mains power is between 220V-240V, then go ahead and plug it in. You won’t have any problems as long as the 250V power cable fits into your 220V-240V wall power outlet and into the amplifier. 240v outlet not delivering 240 volts. To spare you all the long version of my two week nightmare: bought a house built in 1976. Hooked up dryer, switched to 3 prong plug. Dryer ran fine, started to smell like burning plastic until it stopped running altogether. Dryer is fine, power cable apparently gave out. A plug is the connector attached to an electrically-operated device, often via a cable. A socket (also known as a receptacle or outlet) is fixed in place, often on the internal walls of buildings, and is connected to an AC electrical circuit. Inserting ("plugging in") the plug into the socket allows the device to draw power from this circuit. The logical solution is to set the output of the UPS for 240V, because with 240V can be split evenly into two 120V conductors. This would work, if it weren’t for the Make- Before-Break maintenance bypass switch. When that switch is operated, it overlaps the power from utility (120/208V) with the power from the output of the UPS (120/240V). The Utilization voltages are often a compromise. If I rate a motor at 230V, +- 10%, it can work on a 220V system as well as on a 250V system. The same is generally true for 3 phase commercial / industrial systems; 440-460-480 or 208-230-240 (although it can get more complicated by transformer configurations as well). @cybernard "It is not common, but still possible to have a 230v in the US"-- Actually 220-240VAC is not just common, but very likely wired to the typical home. It has two phases, which can be split into two 120V branch circuits. The 240V is available for for high-power appliances such as electric oven, clothes dryer and stationay power tools. QgjlX.
