Probably not, but I have yet to see a 150 volt appliance as this is a non-standard voltage. If you are referring to a 115 volt appliance then the answer is yes you can as 110/115/120 volts tend to be used interchangeably in practice and are close enough together to not affect operation of the appliance.
Yes you can safely do this. A 10 volt difference between the appliance and the outlet will not make a difference.
Do not do this.
Only if it is rated for 110V-220V. If it is rated for 110V only and you plug it into a 220V outlet, your device will be destroyed.
No, the pin configuration would not allow this to happen.
You cannot directly plug a 110v device into a 220v outlet. This can cause damage to the device or even create a safety hazard. You would need a voltage converter or transformer to safely convert the 220v outlet to the appropriate voltage for the 110v device.
permanent attachment to an appliance An appliance plug may have a differently shaped plug, in order to prevent it from being plugged into an ordinary electrical outlet (one with the wrong voltage or power rating).
Yes
No. Attempting to run an appliance on insufficient voltage can cause damage to the appliance and can be dangerous. Call an electrician and get him to install a 220v plug
Yes you can safely do this. Most appliances that are marked 115 volts will operate on outlet between 110 and 120 volts safely.
Do not do this.
If it's rated at 110 then you can safely plug it in to a residential outlet. But, because it is generating heat, it will be drawing substantial voltage so you should ensure that the appliance is on its own circuit; otherwise when someone else turns on a light, or plugs in another appliance, the circuit will overload and shut down.
You will burn up your appliance!!!!!
Only if it is rated for 110V-220V. If it is rated for 110V only and you plug it into a 220V outlet, your device will be destroyed.
Assuming the wiring to the outlet has 2 loads and one neutral, isolate one load from the outlet and use the neutral as the common. be sure to ground from the receptacle to your conduit or ground lead. You should also replace the corresponding breaker with a 120 volt single breaker.
Yes, it uses an AC power adapter.
No, the pin configuration would not allow this to happen.
Yes.
