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.
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.
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.
For residential service 110V, 115V, 117V, 120V, and 125V are all functionally the same. Electric companies have been slowly increasing the line voltage over the last 100 years to cope with increased loads. That is where these different voltages come from. The tolerance is generally +/-10%. That's +/- 11.5 volts in this case. So, a 115VAC appliance will run between 103.5 and 126.5VAC. The short answer is yes. 110V appliances can work with up to 130V without being burnt, additionally, 220V appliances can work with up to 240V without being burnt.
No, the pin configuration would not allow this to happen.
Yes.
