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

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

## Will a 12 2 wire carry 30 amps?

Intentionally overload one 12-2 cable This is also bad, but not as bad as paralleling, but there may be a way to “make it legal”. If you look in the code book, 12 AWG wire is legal to 30 amps if you can run it at 90 degrees C.

## How many amps can a 12 2 wire handle?

## Is Rheem or AO Smith better?

Rheem is a good, mid-level water heater brand that’s not too costly. Its reputation for manufacturing durable, reliable water heaters makes it a good choice for most homes. Overall, AO Smith is probably the better choice for gas water heaters, but only by a fraction.

## What size breaker do I need for a 1500 watt heater?

A 1500-watt heater on a 120-volt circuit thus needs a breaker of 15.6 amps. Because a 15-amp breaker would be too small, you need a breaker with the next highest rating, which is 20 amps. Include the current draw of any other devices on the circuit when calculating the breaker size.

## What size wire do I need for a 4500 watt water heater?

10/2 wireA 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.

## What is the difference between 12 2 and 12 3 wire?

The designation 12/2 indicates AWG 12 wire with two conductors (AC hot and AC neutral), 12/3 indicates AWG 12 wire with three conductors (two AC hot and AC neutral). Both designations also typically include a smaller bare copper earth ground conductor. … AWG 12/3 is used for double breaker 240V 20A max circuits.

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

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.

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

Besides, 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.

## 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.

## 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.

## How many amps is 4800 watts at 240 volts?

20 amps20-amp 240-volt circuit: 20 amps x 240 volts = 4,800 watts.

## What size wire does a water heater need?

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.

## How many amps does a 5500 watt element draw?

20 ampsSo, 5500 watts / 220 volts X 0.80 = 20 amps.

## Can you use 12 2 wire for 220?

If you’re wiring a 220v, 20-amp outlet to run power tools, you can use the same 12-gauge wire you would use for a 110-volt, 20-amp circuit. Remember that the cable must have an extra hot wire. If the appliance draws 30 amps, you need a different type of receptacle, and the cable needs to be 10-gauge.

## 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 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.
