How do you change 115V to230V Gould only has 5 terminal?

To change 115V to 230V using a device with five terminals, you can use a step-up transformer designed for this purpose. Connect the primary side of the transformer to the 115V supply, ensuring that the appropriate terminals are used for input. The secondary side will provide the 230V output. Ensure that the transformer is rated for the required power and that all connections comply with electrical safety standards.
