## What size breaker do I need for a 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..

## What size breaker do I need for a 3500 watt water heater?

-> The 3500 watt element is shown using a minimum 20 amp rated circuit (#12 AWG copper shown) for a 240 volt circuit with a 20 amp overcurrent device (breaker).

## Can I use a 40 amp breaker on 10 gauge wire?

You can play with all the math you want to, but you can’t escape the fact that a #10 wire is rated to carry a maximum of 30 amps and will not be protected by a breaker which won’t snap until more than 40 amps hit it.

## How many amps does a 10kw heater pull?

41.6 ampsFurthermore, how many amps does a 10kw heater pull? 10,000 watts divided by 240 is 41.6 amps.

## What size breaker do I need for a 3000 watt water heater?

A 3000 watt 240 volt can be operated on a 14/2 cable, 15 amp double pole breaker.

## Can I replace a 3800 Watt water heater with a 4500 Watt?

Just so, can I replace a 3800 Watt water heater with a 4500 Watt? You can buy 3800 watt elements to replace the 4500 watt units. This is commonly done when the electric is NOT 10 gauge wire with 30 amp breaker. If it is 12 gauge and 20 amp you are limited to 3800 watt elements.

## How many watts can I run on a 20 amp circuit?

2,400 watts20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts.

## How many amps is a 4500 watt water heater?

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 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.

## How many amps does a water heater pull?

1650 watts/120 volts= 13.75 amps. You need a 14 gauge or larger (12 gauge) wire and a 15 amp breaker for the heater.

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

For example, a 20-amp hot water heater needs 12-gauge wire, a 25-amp hot water heater requires 10-gauge wire, and a 30- to 40-amp hot water heater requires 8-gauge wire. Some large heaters draw up to 50 amps, requiring 6-gauge wire. … The 3800 can be wired with 12/2 wire and a 20 amp breaker.

## What size breaker do I need for a 240 volt heater?

Electricians generally install 240-volt heaters, since they use lower amperage and are more energy-efficient than 120-volt heaters. Adding a 240-volt baseboard heater usually requires a new 20- or 30-amp double-pole circuit breaker and new circuit wiring to supply one or more heater units.

## How many watts does a 40 gallon water heater use?

4500 wattsYour 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 5500 watt water heater?

The math shows that 5500 watt water heater is well within the safe maximum for a 30 amp breaker and 10 gauge wire. When heat exceeds circuit breaker rating, then the breaker trips. A 30 amp breaker with 10 gauge wire has 80% safe maximum = 24 amps. 24 amps x 240 volt = safe maximum 5760 watts.

## Does a gas water heater need a dedicated circuit?

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 wires does a water heater need?

On the top or the side of the hot water heater (depending on the type), you will see the junction box cover where the connections will be made. Remove the screw and the cover. Inside you should see two lead wires and a ground screw.

## Does a water heater need a separate breaker?

A water heater always requires a separate 220-volt circuit and in our case a 30-amp circuit breaker and 10/2 (with ground) circuit cable. … Electric water heaters require a 240-volt dedicated circuit, which serves only the water heater and no other appliances or devices.

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

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.

## Can I replace a 3500 Watt water heater with a 4500 Watt?

When selecting element, buy same wattage or less wattage… keep volts the same. It is ok to install higher watt up to 5500 on 4500 watt heater if breaker is 30 amp and wire is 10 gauge. It is ok to install lower watt: replace 4500 with 3500 as long as voltage is same.

## Is a double pole 30 amp breaker 60 amps?

A main breaker is a large-amperage double breaker, same as any double breaker in the breaker box, except it supplies power to each busbar. So your question is like asking if you can draw 60 amps off a 30 amp double breaker … the answer is NO.

## How many amps does the average refrigerator draw?

20 ampsThe average refrigerator uses approximately 725 watts of electricity and 15 to 20 amps. This energy consumption equals 10 percent or more of your home’s total energy usage.
