The best way to determine which circuit breaker is for the water heater is with a voltage meter, It is suppose to be only one circuit breaker, but in a faulty application it could be two breakers

How is a hot water heater wired from the power source to the heater?

10/3 wire with 30 amp double pole breaker from panel box to water heater.


How do you hook up a water heater with red black and white wires?

Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.


What are the standard size circuit breaker amperages?

In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.


How many watts are used in a hot water heater?

A typical home hot water heater uses 4800 watts. The circuitry connecting to the tanks is a 20 amp breaker with #12 wire for the connection. The tank draws 20 amps. W = A x V = 20 x 240 = 4800 watts. Some industrial hot water tanks can be rated at four times the size of home tanks.


Should a hot water heater be put on a 30 single or 30 double amp breaker?

What governs the type of breaker is the voltage and wattage of the heater elements. If the tank is 120V then you would only use one breaker. The size of the breaker you use will depend on the watts of the element. Watts = amps x volts, Amps = Watts/ volts. Once you establish the amperage then size the wire and the breaker to fit. If the tank is 240V the same rules apply only you would use a 2 pole breaker. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.

How can I reset a hot water heater?

To reset a hot water heater, locate the reset button on the unit and press it. Wait a few minutes for the heater to restart. If the problem persists, check the circuit breaker and pilot light. If needed, consult the manufacturer's manual for specific instructions.


What size amp circuit breaker should be used for a hot water tank?

Assuming you are referring to a 240 volt residential hot water heater you will need to install 10/2 NM cable (Romex) with ground from the service panel to the water heater wired to a 30 amp circuit breaker in the service panel. If you cannot see the water heater from the service panel you will need to install a service disconnect at the water heater.
