# Question: What Size Breaker Do I Need For A 50 Gallon Electric Water Heater?

## How many amps does an electric water heater need?

30-ampElectric hot water heaters typically require a dedicated 30-amp, 240-volt breaker..

## Does a hot water heater need its own breaker?

Water heaters usually need their own circuits as well. Tankless on-demand units must heat water quite rapidly, so they necessitate additional upgrades in many homes. Some compact appliances don’t need dedicated circuits.

## How many amps does a 6 gallon hot water heater draw?

16.7 A Amps6 gal., 120 VAC, 16.7 A Amps, Residential Mini Tank Water Heater.

## What size breaker do I need for a 40 gallon electric water heater?

Your average residential 30 or 40 gallon water heater is 4500 watts and usually goes on a 30 A breaker.

## What size breaker do I need for a 20 gallon electric water heater?

A water heater of this type is required to be considered a continuous load meaning that the branch circuit needs to be calculated at 125% of the heater’s rated ampacity. 4500/240 = 18.75 amps, will work on a 20 amp OCPD but, 18.75*125% = 23.4 amps, requires a 25 or 30 amp circuit.

## What size breaker do I need for a 60 gallon water heater?

## What size circuit breaker do I need for an electric water heater?

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.

## How many amps does a 40 gallon electric water heater draw?

Bottom line, For a 4500w heater w/240v it will draw 4500/240 or 18.75 amps so #10 wire and either 25 or 30 amp breaker, depending on code.

## Can I replace a 4500 Watt water heater with a 5500 Watt?

Can I replace 4500 watt elements with 5500 watt? You can definitely replace 4500 watt with 5500 watt and get 4-7 gallons more hot water from a tank.

## How many amps does a 50 gallon electric water heater use?

18.75 ampsA typical 50 gallon electric water heater runs at 4500 watts. In an electric circuit of 240 volts, 4500 watts is equivalent to 18.75 amps.

## What size of wire do I need for a 30 amp breaker?

Any circuit fused for 30 amps must use a minimum of 10 ga copper or 8 ga alu. Longer runs may require an upgrade of wire size. In your case, use at least 10 copper for your welder regardless how far it is from the breaker panel.

## Can you use 12 2 wire for a water heater?

A 12-2 w/ground should be enough, although I would use a 10/2 for future “upgradability”. 10/2 is the standard cable for a water heater. Connect white to red. 12/2 would be insufficient for almost all water heaters.

## How many amps does a 20 gallon water heater pull?

A 20-amp circuit would be the required size to operate the water heater. This is determined by an Ohm’s law electrical formula: watts divided by voltage equals amps. I’ll even do the math for you. Divide 3,800 watts by 240 volts to determine that you’ll need 15.83 amps to operate your water heater.

## What size breaker do I need for a refrigerator?

Electrical requirements and breaker size for refrigerators are a 115 or 120-volt individual, properly grounded branch circuit, protected by a 15 or 20 amp circuit breaker or time-delay fuse.

## What size breaker do I need for a 4500w water heater?

The wiring requirements are less stringent for 3800 watt elements than for 4500 watt elements. A 4500-watt element requires 10/2 wire and a 30 amp (220volt) breaker. The 3800 can be wired with 12/2 wire and a 20 amp breaker.
