Can I use a 20 amp breaker for water heater?

Electric water heaters use anything between 220 to 250 volts of alternating current. You’ll need a double circuit breaker that is correctly rated for the power draw of the water heater. We’re looking at between 20 Amp and 30 Amp for most electric water heaters.

Can I use a 40 amp breaker for a water heater?

You cannot put a 40A breaker on #10 wire. If you are sure there is (at least) #8 wire all the way from the breaker to the water heater, you can just replace the 30A breaker with a 40A breaker, but if and only if you have verified the size of the wire throughout the entire circuit.

What size breaker do I need for a gas 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.

How many amps does a gas hot water heater use?

How Many Amps Does a Gas Water Heater Use? A gas water heater with a tank will require 30 amps of electricity, which usually does not require any kind of modifications to the home’s electrical system–even for older homes with only a total 100- or 200-amp service.

Does a gas hot water heater use any electricity?

What About a Gas Water Heater? Modern gas water heaters are in the same boat as electrical ones, unfortunately. They still use electricity to ignite the pilot and to maintain temperatures and detect your hot water supply needs.

What kind of circuit breaker do I need for a hot 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.

How many amps does an electric water heater need?

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 big of a breaker do I need for a 4500 watt 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.

Why is my water heater Tripping the breaker?

Reasons Your Water Heater Is Tripping the Breaker The problem could be: The breaker may be worn out and trip. A wire also may be loose in the electrical panel, causing a short circuit. Your thermostat – If your thermostat goes bad, it can draw more electricity than the circuit can handle, causing the breaker to trip.
