Which breaker is for heater?
Electric furnaces will have two pole breakers. You need only check the single lever breakers that supply 120 volts to your home circuits. The double lever breakers that are marked 240V below feed those appliances in your home like your range, clothes dryer, electric water heater, etc.
Why does my electric heater keep tripping the breaker?
Common Reasons Why a Heater Might Trip the Breaker The most likely reason is that the heater is drawing too much current and overheating that circuit. This can be dangerous, so the breaker shuts off to protect you. A second reason is that you might have too many other appliances on the circuit.
What causes heater breaker to trip?
A strained blower is the main trigger for a tripped circuit breaker. Blocked air vents: Another way that the blower motor may be placed under too much stress is if there are blocked air vents around the house. This might be from moved furniture or people closing off the vent louvers.
How do I stop my breaker from tripping the heater?
The first thing to do when a space heater trips the circuit breaker is to see if you are running the heater on the highest level. Most heaters have 2 settings for watts used. If your has that, reset the breaker and try to use it at the lower level. It might work fine on LOW heat (without tripping) but not on HIGH heat.
What size breaker do I need for a furnace?
The size of a breaker is determined by the amp draw. The exact amps an electric furnace requires is solely based on the size of the furnace and its performance capabilities; however, typically electric furnaces require a draw between 60 and 80 amps.
Why does my breaker trip when nothing is plugged in?
The reason why it’s nearly impossible for a circuit breaker to trip without devices being plugged in is because, sometimes, the breaker has simply gone bad and is just malfunctioning. There’s nothing you can do in this case but switch it out for another.
How do you check if outlets are on the same circuit?
Plug the lamp into another outlet to determine whether or not that outlet is on the same circuit. If the lamp lights with the breaker still off, then the outlet is on a different circuit. If the lamp doesn’t light, then it is on the same circuit as the original outlet.
How big of a breaker do you need for an 18 Amp heater?
While this does make a valid point, it does not answer the question. – Tester101 Sep 18 ’13 at 9:58 In America the NEC requires 125% protection of circuit so if you have an 18 amp heater then you would need to account for 23.4 amp. Meaning you would need a 30 amp circuit breaker and 10 gauge wiring. Can you cite the code section?
How do you determine the size of a heater circuit breaker?
You can derive the current from a simple formula. Look for the heater’s specifications label. Divide the power specified on the label by its operating voltage to obtain the maximum current draw. Multiply the value for current by 125 percent to determine the size of the breaker you need for the heater.
How many amps does a NEC heater need?

How big of a circuit breaker do I need for an apartment?
When that happens, the only thing that can keep that wire from burning up inside your walls is a breaker rated at no more amperage than the maximum the wire is able to carry safely. Apartment-size ranges require at least a #8 wire and full-size ranges require a #6 wire.
