(For example: 2-1000W & 1-1500W, 240V heaters = 3500 Watts total. These 3 heaters would require 12/2 wire and a 20 Amp 2-Pole breaker if they were to all be placed on the same circuit. If more heaters are needed either run a new circuit or increase the wire and breaker size to accommodate the load.)
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.
Thereof, 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.
Also to know is, 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.
Subsequently, question is, What size circuit breaker do I need for an electric 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.
Also, 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.
What size breaker do I need for a 60 gallon water heater?
If you are replacing a 40-gallon water heater with a 60-gallon one, or if your electrical panel is older, you may have to upgrade it. The 2-10 copper wire and 30-amp breaker combination is compatible with all water heater models.
How many amps does a 40 gallon electric water heater use?
Bottom line, For a 4500w heater w/240v it will draw 4500/240 or 18.75 amps so #10 wire and either 25 or 30 amp breaker, depending on code.
What size breaker do I need for a 4000 watt heater?
What size breaker do I need for a 4000 watt heater? Therefore with a 4000 Watt heater at 240 volts the ampacity is 16.666 amperes and if you multiply this by 125% you are required conductors and an overcurrent protective device that are rated at least 20.83 amperes.
What size breaker do I need for a 50 gallon electric 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 4500 watt water heater draw?
18.75 amps
What size breaker does a 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.
What size circuit breaker do I need for a hot 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 2500 watt heater?
At 120 volts, a 2500 watt load (heater) consumes roughly 20 amps. You would need a 30 amp breaker and #10 AWG wiring from the breaker to the heater.
How many amps does a 10 gallon water heater pull?
16.7 A Amps
How many amps does a 40 gallon hot water tank use?
Bottom line, For a 4500w heater w/240v it will draw 4500/240 or 18.75 amps so #10 wire and either 25 or 30 amp breaker, depending on code.
How many amps does an electric water heater use?
30-amp
How many amps does a 2500 watt heater draw?
Watts: Amps (at 120V):
—————— —————
1500 Watts to amps 12.17 Amps
1800 Watts to amps 15.00 Amps
2000 Watts to amps 16.67 Amps
2500 Watts to amps 20.83 Amps
