Actually it is irrelevant what water heater is used, you can’t use #12 for any water heater on a 30A breaker. That’s true, but if the breaker is 30A, it’s usually not hard or expensive to change it to a 20A breaker.

Can you use a 30 amp breaker for a water heater?

Electric water heaters require a dedicated 240-volt dedicated 30-amp circuit and a 10-2 non-metallic (NM) or MC cable. This means the breaker only powers the water heater and no other appliances. A 30-amp circuit breaker can power all 4500watt water heaters regardless of gallon size.

Should a water heater be on its own circuit?

Basically, any electrical devices that need to work in order to protect your family, valuables, and property must be put on a dedicated circuit. These include: Sump pump. Water heater.

Can I run a 30 amp heater on a 40 amp breaker?

ABSOLUTELY NOT. You can use a 30A circuit for electric heat, but not larger.

What size breaker do I need for a 30 gallon electric water heater?

30 Amp

The branch circuit needs to be calculated at 125% of the rated ampacity for this type of water heater to be considered a continuous load. In order to work on a 20 Amp OCPD, you will need a 25 or 30 Amp circuit.

What should be on its own circuit?

Appliances drawing enough power to require their own circuit include ovens, stoves, dryers, washing machines, dishwashers and hot tubs. Some garbage disposals, space heaters, microwaves, refrigerators, freezers and garbage disposals also might require enough wattage to demand separate circuits.

Does a gas water heater need to be on its own circuit?

A tiny amount of power is all it takes to ignite the flame. Unless the manufacturer requires it, there’s no need for a dedicated circuit.

What size wire would you run for a 30 amp breaker connected to a electric water heater?

Electrical wires

Since the generic breaker size for water heaters is 30-amps, the best wire size is a #10 American Wiring Gauge (AWG).

What size wire should I use for a 30 amp breaker?

For a maximum of 30 amps, you’ll need a wire gauge of 10. The most common household item that requires a 30 amp circuit is a central air conditioner.

What kind of breaker do I need for a water heater?

30-amp

Electric water heaters require a 240-volt dedicated circuit, which serves only the water heater and no other appliances or devices. The circuit wiring typically includes a 30-amp double-pole breaker and 10-2 non-metallic (NM) or MC cable.

What kind of breaker do I need for a 30 amp water heater?

Also, consider your breaker size for water heater. 30-amp circuit breakers, commonly used for a large boiler tank, require a 10-2 non-metallic or MC cable.

Can I use a 50 amp breaker for a 30 amp water heater?

50A plug on a 30A device is fine, but flipping it around, a 30A plug on a 50A device will burn, and big lawsuits and fines will come.

Does a water heater need a GFCI breaker?

Similarly to your washing machine, outlets within 6 feet of your water heater should also be GFCIs. One basement outlet. If you own an unfinished basement with outlets, at least one of them needs to be a GFCI.

Why does my water heater keep tripping the circuit breaker?

Altogether, the answer to your question “why does your water heater keep tripping the breaker” is simple: you either have a faulty breaker, a bad heating element, or damaged wiring. With these anomalies, it is necessary for you to find out where the problem takes place.

Do 220v circuits require GFCI?

Where GFCIs Are Required. GFCI protection is required for 125-volt to 250-volt receptacles supplied by single-phase branch circuits rated 150 volts or less to the ground. GFCI receptacles are required in bathrooms, garages, crawl spaces, basements, laundry rooms and areas where a water source is present.

Is a tankless water heater considered a continuous load?

Electrical Service:

The Heatworks MODEL 1 tankless water heater is considered a non- continuous heating appliance according to the Definitions in the National Electric Code. An appliance load that is not continuous for 3 hours or more is considered non-continuous.

What is the required branch circuit for A 25 A space heater?

21A

After multiplying the load by 125 percent, the branch-circuit rating for this heater shall be at least 21A (16.67 × 125% = 20.8 = 21). Therefore, the breaker’s rating must be at least 21A. In accordance with 240.6(A), the next standard rating higher than 21A is 25A.

Is an electric water heater considered A continuous load?

A fixed-storage-type water heater that has a capacity of 120 gallons or less shall be considered a continuous load for the purposes of sizing branch circuits. Because of 422.13, this water heater shall be considered a continuous load.
