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.

Also, 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.

In this way, Should I get a 4500 or 5500 watt water heater? (1) If your heater has 4500 watt elements then that’s running the breaker and wire at cooler temperature than 5500 watt. .Therefore, from conservation perspective the 4500 watt is better than 5500 watt.

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

It may say on the side of it also. How many watts? Your average residential 30 or 40 gallon water heater is 4500 watts and usually goes on a 30 A breaker.

Can I put a higher wattage element in my water heater?

Due to liability, I can not recommend that you increase the element wattage over the original element installed by the manufacturer. If you do decide to use a higher watt elements, be sure the water heater is wired with #10 wire from the breaker to the heater and that a 30 amp breaker is used.

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

You need a 30 amp 2-pole breaker and #10 AWG wire.

What size breaker do I need for a 2000 watt water heater?

The bottom line is, a 2000 watt 120 volt water heater should be on a 30 amp circuit consisting of #10 wire and a 30 amp single pole circuit breaker.

Are all electric water heater elements the same?

Are all electric hot water heater elements the same? There are three types: screw in, bolt in and clamp in. They all have different wattage ratings and can work on either 120 or 240 voltage.

What size breaker do I need for a 50 gallon water heater?

The standard for water heater circuits is #10, two conductors with ground (10/2) and a 30 amp circuit breaker for a water heater.

What size breaker do I need for a 6000 watt water heater?

What causes water heater elements to burn out?

The most common cause of burned out elements on new water heater installations or new element replacements is DRYFIRE. This happens because the installer fails to open a hot water faucet while the heater tank is filling with water and therefore purging or bleeding air from the system.

Can you replace a 4500 Watt water heater with a 5500 Watt?

Both 4500 and 5500 watt water heaters are NOT correct if breaker is 20 amp and wire size is 12 gauge. The answer for 20 amp breaker and 12 gauge wire is to install 3500 watt elements.

What wire do I use for water heater?

Common Current and Wire Gauge Sizes

Wire a hot water heater with wire that’s sized to accommodate the heater’s current requirement. 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.

Should I replace both water heater elements?

Both heating elements generally do not work simultaneously. It is also the element that cycles on first because of the temperature drop when water enters the tank. I recommend replacing both elements since you have to drain the tank to clean flush the sediment out anyway.

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.

Are upper and lower water heater elements the same?

The top and bottom elements are controlled by separate thermostats. When the water on the top of the tank is hot, the top element turns off and the lower one heats. The upper and lower heating elements never come on at the same time.

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

So, if you have a heater using 6,000 watts in total in a 240-volt connection, the operative ampere total would be 25 Amp. In this case, you need no less than 35 Amp. Because it will use 25 Amp in total, getting a 30 Amp breaker will cover it safely, but a 35 Amp unit will cover more than just a heater if needed.

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

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 I use a lower wattage water heater element?

It is ok to install lower watt: replace 4500 with 3500 as long as voltage is same. Lower watt means less heat, so element can last longer. Density: All new water heaters come with high density elements. 240 volt 4500 watt element heats about 21-40 gallons per hour.

Can I use a lower wattage water heater element?

Electricians generally recommend 240volt because it uses lower amperage and is more energy-efficient than 120-volt. Adding a 240volt 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.

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

Since this is a purely resistive load 5500 watts at 240 volts is 23 amps, breaker is sized at 30 amps and 10 awg wiring is used.
