Change
water heater from 240Volt to 120Volt 120Volt is slower recovery, and for homes with low consumption. Wires inside heater remain the same. Typical 240Volt water heater will work when connected to 120V or 240V <> if wires from breaker box are connected correctly as shown. Hot wire from 120Volt breaker connects to Black wire at top of heater. White Neutral wire connects to Red wire at top of heater. Connecting Black wire to Black wire ensures that thermostats are turning the Hot wire on-and-off. This is electrically safe. Elements will heat with 120V or 240V, when wires from breaker box are connected as shown. How to wire thermostats How to wire off-peak water heater |

How to
convert 240 Volt circuit to 120 Volt circuit: Image shows typical 240V water heater circuit. To convert to 120V: Move black wire from 240V breaker to 120Volt circuit breaker rated for correct amps. 30 amp breakers and 10gauge wire run cooler with less heat loss. Circuit is more efficient, and breaker box lasts longer. Move white wire from 240V breaker to Neutral busbar where ground wire connects. Some breaker boxes have separate Neutral busbar where white wires are connected. Basic 240Volt water heater circuit How to replace circuit breaker How to install subpanel |

 | Timer toggles water heater between 120Volt and 240Volt Use SPDT timer with dry NO NC relay terminals to change water heater between 120Volt and 240Volt Use 120Volt at peak-electric price. Water heater recovers slowly with 120Volt. Use 240Volt when electric prices are lower, and faster recovery is needed.  Intermatic GM40 series Dry terminals mean NO NC COM terminals are independent and receive no power when power is applied to timer clock on terminals H and N. | ||||||||||||||||||
