Different countries have different legal limits to how much their electricity supply voltages may vary. In the UK, for example, the nominal supply voltage for residential supplies is 230 V, but this is allowed to vary between -6% and +10%. So, as you can see, and 'actual' voltage of 250 V is within the allowable upper limit (253 V) for the nominal voltage of 230 V. So, to answer your question, you need to check what the allowable variation is at your location (your electricity supplier can confirm this) -I would guess that 250 V would be well within the allowance for 240 V.

∙ 11y agoIn North America, the voltage from a normal wall socket is typically 120 volts.
Nominal ( Means Ideal or what we tell you it should be )120 volts AC Any voltage at or over 105 volts will make everything operate normally Expect to see 110 volts to 117 volts in your home depending on what you are running.
If you are only getting 118 volts on a 120 volt outlet, it is within an acceptable range due to minor fluctuations in voltage. It may not necessarily indicate a problem with the outlet, but if you consistently experience voltage drops, it could be due to issues with the wiring or electrical connection that may need to be inspected by a professional electrician.

Power supply voltages vary with the amount of load placed on them. In many countries the supply voltage has a nominal voltage and a plus or minus tolerance. In the UK the nominal voltage is 230 v but the allowable variation is -6% +10%, in other words 216-253. At my house the voltage is usually between about 236 and 253 volts.
The nominal voltage of a Duracell DL123 battery is 3 (lithium) nominal volts or 3.6 (Li-ion) nominal volts.
You should be getting 14 volts from the alternator.

A C cell is fully discharged at 0.9 volts, 60% of the nominal 1.5 v.
12 volts DC (nominal). It's the voltage of the battery which will vary from a low of about 11 to a high of about 14 when the engine is running.
It's possible that there is an issue with the electrical circuit or outlet itself. You may want to check the circuit breaker to see if it has tripped or if there are any loose connections. If you are not comfortable doing this yourself, it's recommended to call a qualified electrician to investigate and resolve the issue to avoid any potential hazards.

Most fuel pumps should read about 9 volts, but I think I remember some reading about 5 volts. Why do you need to the voltage at the pump?
The standard nominal mains supply everywhere in the USA is 120 volts AC, 60 Hz.
