A reading of 145 volts is high. The first thing that I would check is the accuracy of your meter. Check the voltage reading at different locations for example, friends homes, to see if the reading is still high there. If it is check your meter reading against another meter. If you are sure that your meter and reading is correct then call the utility company and get them to check the voltage for you.
You would have to run new wires to obtain 240 volts or use a step-up transformer.
The outlet may have a higher voltage reading due to an issue with the wiring, a problem with the outlet itself, or a problem with the electrical panel. It's important to have a qualified electrician investigate and address this issue to ensure the safety of your electrical system.
A 210-volt outlet is not a standard voltage for residential use in most regions. Typical household outlets are either 120 volts or 240 volts. It is possible that a 210-volt outlet may be used in certain commercial or industrial settings for specific equipment or machinery that requires this voltage level. It is essential to consult with a licensed electrician before attempting to use or modify any electrical outlet.
A 30 amp circuit on a 250 volt service could handle up to 7500 watts. That's if it's actually 250 volts coming in. You should check that with your meter.
No, it is not safe to plug a 115 volt appliance into a 100 volt outlet. The appliance may not function properly or may get damaged. It is recommended to use the appliance with the correct voltage to avoid any safety hazards.
12.6 volts as read with a digital DC volt meter.
14 volts
All voltage reading are usually read with a volt meter. This volt meter can be a hand held unit like electricians use.
It is a 12 volt battery. Fully charged it will read 12.6 volts with a digital volt meter.
A fully charged 12 volt battery will output 12.6 volts are read with a digital volt meter.
A fully charged 12 volt automobile battery will read 12.6 volts with a digital volt meter. It will read 12.4 at 75% charge, 12.2 volts at 50% charge and 12 volts at 25% charge.
Volts
A device that measures volts.
Fully charged it should read 12.6 volts with a digital volt meter. 12.4 = 75% charge, 12.2 = 50%, 12.0 = 25%.
You would have to run new wires to obtain 240 volts or use a step-up transformer.
A volt meter or a multimeter on the voltage scale.
With engine not running it should read 12.6 volts if it is fully charged. You will need a digital volt meter to check it.
