What is the voltage output in a standard electrical outlet?
Depends on where you are. In Canada and USA this is the standard voltage. You will need a dedicated outlet, and if you plug anything extra in it, you may blow the breaker. Also you will need a close outlet as extension cords are not recommended with these high currents. If you really must use an extension cord, get a 12 or 14 guage wire (extra heavy duty) cord.
