This depends on where the power is coming from - and how you are measuring it.
If the power is coming from an auxiliary generator, the generator's motor is running too fast.
If the power is coming from the electrical company:
(a) You might be using a poorly calibrated meter to measure it (you are getting the wrong answer from the meter)
OR
(b) You have a true problem with your electrical power and need to get either the power company or an electrician in pronto to fix it.
If the voltage coming in to your house is TRULY 167 volts, you run the grave risk of damaging things connected to it.
No conversion needed. These are nominal voltages which range from 110 to 120 volts. It will operate fine on the outlet.
it is likely that a floating neutral is the cause of this problem
Not unless you have a 110 volt supply to plug it in to. The standard General Power Outlet in Australia is 240 volts AC at 50 Hertz.
Yes, normally, assuming it's 60 cycle (hertz) AC. In the USA, 110 volts as such is no longer used, it's really 120 plus or minus about 5 volts everywhere.
The United States is one of the only places in the world that uses 110 volts instead 220 volts. In order to operate 208 volts on a 110 volt electrical current, you will need a voltage converter.
can you plug a 115 volt into a 110 volt
NO
You don't. Voltages are a nominal rating. 110 volts is within the nominal range at this potential. The voltage centre line is 115 volts. Utility companies are mandated to keep voltages locked within 5% of a centre line voltage. This means that it could be as high as 115 + 5% = 120.75 volts and as low as 115 - 5% = 109.25 volts
Yes - usually house voltage varies from 110 to 120 volts.
Not unless you have a 110 volt supply to plug it in to. The standard General Power Outlet in Australia is 240 volts AC at 50 Hertz.
If you combine two 110 volt power lines it does not give you 220 volts, the voltage will be the same. The only way to turn 110 volts into 220 volts is with a step-up transformer.
If the plug is not specifically labeled 110 volts AC, check the owner's manual before using it for such devices as radios or other electronic equipment.
