How do you connect water heater to portable generator?

To connect a water heater to a portable generator, first ensure the generator can handle the wattage of the water heater. Use a heavy-duty extension cord rated for the generator and water heater's power requirements. Connect the generator to a transfer switch or directly to the water heater's power input, following all safety protocols. Always consult the manufacturer's guidelines and local electrical codes to ensure safe and compliant connections.
