5 Space Heaters That Won’t Trip Breaker

Why Do Electric Space Heaters Keep Tripping Circuit Breakers?

There are several reasons why electric space heaters keep tripping circuit breakers. First, the electric space heater may be drawing a lot of current from the circuit.

Generally, space heaters are rated 1,500W.

If your heater draws a lot of current from the circuit, then the fuse automatically breaks the circuit to prevent you and the device from damage.

Overloads may occur when you have your heater on a dedicated circuit or a general one. If you have your heater on a general circuit, then the chances are that the other devices on the current may contribute to the problem.

General home appliances such as fridges and washing machines consume a lot of current from circuits. If you let such devices share a current with your space heater, the circuit will likely break. Make sure you know how many amps your heater uses because it needs a dedicated circuit.

On other occasions, your space heater may keep tripping the circuit breaker even if it is connected to a dedicated circuit.

This incident may occur because your heater merely consumes a lot of power and overloads the dedicated circuit. You will have to reset the circuit breaker to use your heater continually.

Alternatively, the circuit breaker itself may be quite old or even damaged. If the circuit breaker is faulty, it will keep on tripping even when your space heater is operating on the low heating mode.

How to Prevent an Electric Heater from Tripping Circuit Breakers

One, you can limit the number of devices that are on a general circuit. The total number of appliances on a general circuit determines whether there is enough capacity for all of them.

Your space heater draws about 12.5A of current from the circuit when operating on the high heating mode.

If you connect the heater to a standard 15A circuit, then it means that you can only use it with another device that draws minimal current from the circuit.

If you attempt to connect an appliance that needs 10A, the space heater will immediately trip the circuit breaker.

Two, try running the heater on the low heat setting. It is common for heaters to have several heating modes, including the low and eco modes.

When heaters are set on the low mode, they consume less power than when they run on the high mode.

However, you will have to bear with less heat produced if you choose to operate your heater on the low heat mode. If doing this does not compromise your home’s comfort, then it may be a wise idea to stick to it and minimize cases of your heater tripping the breaker.

What are the Signs of a Bad Circuit Breaker?

Having a faulty circuit breaker can greatly put you and your appliances at risk.

Luckily, replacing a circuit breaker is an easy job that any certified electrician can do for you. But before you get to that, you must be certain that your circuit breaker is faulty.

Here are a few vital signs that you should look out for.

  • Reduced performance of your appliances. The way some appliances in your home, including electric jugs and washing machines, function may point to a faulty circuit breaker. If your washing machine repeatedly stops mid-cycle or your jug does not heat the water to the required temperature, then the chances are that there is a problem with your circuit breaker.
  • Flickering lights. If the lights in your home keep flickering, then there may be a problem with your circuit breaker. Commonly, flickering lights occur together with reduced performance in some of your appliances. If you have all these signals in your home, then it may be time to check your circuit breaker for any fault.
  • Burning smell. The smell of burning cables and plastics may indicate that there is a problem with your circuit breaker. If the breaker cannot effectively cut out the power supply, overheating appliances may produce a burning smell. If you have a burning smell in your house, get an electrician to check your circuit breaker.

How Do you Know if a Circuit Breaker Needs to be Replaced?

First, if your panel has not been serviced for more than ten years, you need to replace your circuit breaker. Circuit breakers are designed to last for many years.

However, the longevity of circuit breakers does not mean that you do not need to replace them. If your circuit breakers are over ten years old, then get an electrician to assess and possibly replace them.

Two, if your circuit breaker has physical damage signs, then it is time to replace it. The signs may be in the form of damaged wires or missing parts.

Using a physically damaged circuit breaker exposes you to the danger of fire outbreaks because the device may fail to break the circuit when there is an overload.

Three, if the breaker does not stay on the reset mode for a long time, get an electrician to replace it. The problem may either be in the circuitry’s wiring or that the circuit breaker itself is faulty.

Other safety precautions to take when running an electric heater

  • Do not use your heater on an extension cord. Extension cords are not designed to handle the heavy amperage and wattage needs of devices like heaters. If you connect your heater to an extension cable, you will likely experience an overload and possibly a fire outbreak resulting from the cable failing to maintain the heater.
  • Keep combustible materials away from the heater. Ensure that the materials which can easily catch fire are nowhere near your heaters. Such materials can cause fire outbreaks in your home if they get into contact with the hot surface of an electric heater.
  • Switch the heater off when it is not in use. It is wise to unplug and store your space heater safely when you are not using it to minimize the chances of accidents occurring.
