Most residential water heaters use either 120 or 240 volts, and they typically require a 20 or 30 amp circuit breaker.
If you’re in the market for a new water heater, you may be wondering if you need a 30 amp breaker. The answer depends on the size and type of water heater you have. If you have a small electric water heater, then a 30 amp breaker should be plenty.

What Kind of Breaker Do I Need for a 30 Amp Water Heater?
If you have a 30 amp water heater, you will need a breaker that is rated for 30 amps. This is the most common type of breaker used for water heaters.
Does a Water Heater Need a Double 30 Amp Breaker?
While many appliances require a double breaker for safety reasons, this is not the case with water heaters. In fact, most water heaters only require a single 30 amp breaker. The main reason for this is that water heaters typically don’t use as much power as other appliances.
However, there are some exceptions to this rule. If your water heater is particularly large or uses a lot of power, then it may require a double breaker. You should check with your appliance’s manufacturer to be sure.
What Size Breaker Do I Need for My Water Heater?
If you’re in the process of wiring up a new water heater, or replacing an old one, you’ll need to know what size breaker to use. This is determined by the wattage of the water heater and the voltage of your electrical system.
For a standard 120 volt system, you’ll need a breaker that’s rated for at least 15 amps.
If your water heater is 240 volts, you’ll need a 30 amp breaker.
Some newer models of water heaters are “smart” and have built-in energy management features. These can be controlled with a mobile app and will automatically regulate heating based on demand, which can save you money on your energy bill.
If you have one of these smart heaters, make sure to get a compatible breaker.
Installing the wrong size breaker is not only dangerous, but it can also damage your water heater or cause it to malfunction. So if you’re unsure about what size to get, always err on the side of caution and go with a bigger one.
Can I Use a 40 Amp Breaker for a 30 Amp Hot Water Heater?
No, you cannot use a 40 amp breaker for a 30 amp hot water heater. A 40 amp breaker is rated for a circuit that can handle up to 40 amps of current, and a 30 amp hot water heater only requires up to 30 amps. If you were to use a 40 amp breaker, it would be oversized for the circuit and could create safety issues.

How to Wire a 30 Amp Breaker for a Water Heater
If you need to wire a 30-amp breaker for a water heater, the first thing you’ll need to do is turn off the power to the circuit breaker panel. Once the power is off, you can remove the cover from the panel and locate the correct breaker. With the cover off, use a voltage tester to make sure that there is no power going to the breaker.
If there is power, turn off the main switch before proceeding.
Next, identify the wires that are coming into contact with the metal screws on either side of the breaker. The black wire should be on one side and the white wire on the other.
Loosen these screws and place them around each of these wires before tightening them back down.
Now, take your new 30-amp breaker and line it up with where the old one was positioned in order to insert it into its slot. Be sure that both sides ofthe new breaker are securely snapped into place before turning onthe main switch and restoring power tothe circuitbreaker panel.
