The basic operation of a two thermostat system (upper and lower) on an electric water heater of 240 volt supply is as follows: Only one element will come on at any one time. This is known as a flip/flop system. On a 240 volt water heater, there will always be 120 volts to both elements.120V AC Single Phase Dual Element Water Heater Thermostat Wiring. In non-simultaneous water heater thermostat wiring, the Phase or Hot “L” is connected to the left terminal L1 of the upper thermostat and Neutral “N” is connected to the right terminal L3. Two wires are outgoing from L4 as neutral to the upper and lower heater elements. In the above diagram, I show that the upper water heater element is switched OFF and the lower heater element is switched ON. Note that this element is 220 volts rating and you can also 440 volts heater elements but you need to provide the line supply, my mean lines or two hot wires supply 440 volts.In this video: Electric Water Heater Lesson Wiring Schematic and Operation.

Most electric water heaters need a 30 amp 240 volt circuit, using a 30 amp 2 pole breaker and #10 2 wire cable with ground. Check the wattage and voltage of the unit. A 30 amp 240 volt circuit can handle up to 5760 watts.Total wattage = 9000 Watts. Load Current = 9000 / 120V = 75A. We have used separate circuit breaker for each heating element, the breaker rating size for single element would be: Wattage: = 9000W / 2 = 4500 Watts. Load Current = 4.5kW / 120V = 37.5A. Breaker Size should be 1.25 (125%) of the load current: 37.5A x 1.25 = 46.875A.C. RATING PLATE MODIFICATION OF SINGLE ELEMENT ELECTRIC WATER HEATERS.
