Question

How many amps does a 240 volt hot water heater draw?

Answer 1

A 240 volt hot water heater draws around 22 to 23 amps and requires at least a 30 amp breaker and 10-2 wire.

A water heater needs it's own breaker and own circuit.

Whether the water heater is 120 volt or 240 volt it requires a dedicated circuit and it's own breaker without any other appliances or outlets on the circuit.

Most electric water heaters require a 30 amp circuit breaker and 10-2 wire unless it's a 120 volt water heater and in that case the 120 volt water heater requires a 20 amp breaker and 12-2 wire.

The size breaker that is required for a hot water tank with a 240 volt heating element that draws 4500 watt is 30 amps and you need at least 10-2 copper wire.

The amp breaker you need for a 240V 40 gallon electric water heater is 30 amp breaker and 10-2 copper wire.

Most 240 volt electric water heaters are a 30 amp breaker.

An electric water heater is most often a 30 amp breaker although it can vary depending on the water heater you have and how many watts is uses as well.

However the majority of 240 volt electric water heaters require 10-2 copper wire and a 30 amp breaker.

110 Volt Water heaters are usually 13.75 amps to 15 amps and you would need at least a 20 amp breaker and 12-2 copper wire.

Some 220 volt or 240 volt water heaters use only 22 amps but you need at least a 30 amp breaker and the 10-2 wire to be sufficient enough to power the water heater without tripping the breaker.

240 volt electric water heaters require a 240-volt dedicated circuit, which serves only the electric water heater and no other appliances or devices.

The circuit wiring for a 240 electric water heater typically includes a 30-amp double-pole circuit breaker and 10-2 non-metallic (NM) or MC cable.

Answer 2

From my experience, the amp draw of a 240-volt hot water heater can vary depending on a few factors. Things like the size of the heater, its efficiency rating, and even the temperature setting can all play a role in determining how many amps it pulls.In my case, when I had my hot water heater installed, I remember checking the specifications to see the amp rating. It turned out to be around 20 amps, which seemed pretty standard for a residential unit of that size.Of course, it's always a good idea to double-check with the manufacturer's guidelines to ensure everything is up to code. And if you're ever looking to beef up your circuit protection, MCBs could offer that extra layer of safety and peace of mind.
