Wiring Connections for an Electric Water Heater

Unlike a new electric dryer for example, which has a 120 volt control timer, an electric water heater does not yet have 120 volt controls. The 240 volt heating elements of the water heater are similar to most kitchen ranges and cook tops which have 240 volt heating elements which do not require a neutral wire as well.
