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.
There is no problem with that voltage. As long as the voltage is plus or minus 5% of the nominal voltage of 115 volts it is considered to be in the 120 volt range.
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.
In North America a nominal voltage of 110 to 120 volts comes out of a normal wall socket.
This is strange, check the scale on your meter that you are reading, to make sure that you are on the correct voltage scale. If the reading is correct the suggestion would be to get an electrician to look into why there is such a voltage drop on the outlet. Don't read the voltage across the device, read the voltage from the "hot" wire to ground. That should be 120 volts. If you get that reading then there is a problem with the neutral. It could be loose or have a high resistive condition.
you can use two hot wire different phases with a double pole braker .
The nominal voltage of a Duracell DL123 battery is 3 (lithium) nominal volts or 3.6 (Li-ion) nominal volts.
There is no problem with that voltage. As long as the voltage is plus or minus 5% of the nominal voltage of 115 volts it is considered to be in the 120 volt range.
You should be getting 14 volts from the alternator.
Low Voltage

A C cell is fully discharged at 0.9 volts, 60% of the nominal 1.5 v.
In North America a nominal voltage of 110 to 120 volts comes out of a normal wall socket.
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.

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.
