If your space heater is plugged into a ground fault circuit interrupter (GFCI) and it trips, don't assume there is something wrong with the GFCI. Immediately stop using the heater until a professional can check it— if not, a serious shock could occur. Replace older space heaters with newer, safer models.
It's a useful protection against shocks, overheating appliances and other issues. Always make sure that your space heater is plugged into a GFCI outlet.
Use Dedicated Circuits: Whenever possible, plug your space heater into a dedicated circuit. This is a circuit not shared by other appliances, reducing the risk of overload.
Overloaded Circuit
This may happen if you connect malfunctioning or defective appliances. Loose, corroded wires or connections may also be to blame. Once the GFCI outlet senses an overload, it trips or "breaks" the circuit.
Another reason why a refrigerator or freezer should not be on a GFCI outlet is because GFCI outlets are often “daisy chained.” This means that one GFCI circuit can be connected to multiple outlets in the kitchen or garage.
If the GFCI still won't click, there is likely a downstream ground fault. However, the GFCI may be miswired. A recently installed device may have a reversed line and load or may need more current. Also, make sure you push the button far enough.
Make sure that the refrigerator outlet or receptacle isn't sharing the circuit with another item, like an extension cord or decorative outdoor lights. The cord may be damaged, and the lights can have enough leakage current to trip the GFCI. This is why having a dedicated refrigerator circuit can be a benefit.
GFCI outlets: Generally, GFCI outlets last somewhere between 15 to 25 years and should be replaced in this timeframe. While these outlets tend to work for a long time, you should test them regularly with the “Test” and “Reset” buttons.
The GFCI will “sense” the difference in the amount of electricity flowing into the circuit to that flowing out, even in amounts of current as small as 4 or 5 milliamps. The GFCI reacts quickly (less than one-tenth of a second) to trip or shut off the circuit.
Reasons Why Your Microwave Is Tripping Your Breaker
In order for this type of reaction to occur, there must be one of two issues at hand: Too many items are plugged into the same circuit that the microwave oven is on, causing an overload. The microwave oven is defective and drawing an excessive amount of electricity.
This means that a 1500-watt space heater can potentially trip a 15-amp breaker, especially if other devices are connected to the same circuit. It is important to note that some space heaters may have a higher wattage, which further increases the likelihood of tripping a circuit breaker.
Space heaters should always reside preferably on a 20 amp dedicated circuit and the breaker won't overload or trip. Most space heaters are approximately 1500 watts. For example, if plugging in two space heaters onto the same circuit, most likely the circuit breaker will overload and trip.
How much electricity does a space heater use? Generally, space heaters use 1,500 watts (W) of electricity, depending on the model. Most space heaters use about 15 amps and connect to a 120-volt outlet. How much you run your space heater has the biggest impact on how much electricity it uses over time.
If your space heater is plugged into a ground fault circuit interrupter (GFCI) and it trips, don't assume there is something wrong with the GFCI. Immediately stop using the heater until a professional can check it— if not, a serious shock can occur. Never leave space heaters unattended.
Keep the space heater at least 3 feet away from combustible materials, such as furniture, bedding, and curtains. A taller heater may need to be even farther away. Don't use a heater in a workshop or garage near flammable paints, gas cans, or matches. Turn it off when you leave the room or go to bed.
Installing dedicated outlets for space heaters is key to prevent overloading your existing circuits and mitigating the risk of electrical fires. Dedicated outlets should also optimize your heater's performance to provide a secure and uninterrupted power supply.
You can safely run a 15 A GFCI on a 20 A circuit because it has lower power requirements. Conversely, using a 20 Amp GFCI on a 15 Amp circuit (if it were possible) would draw more power than it can handle, causing the breaker to trip. And if the breaker doesn't work, the excessive load can start a fire.
Generally, hair dryers use between 1,500 and 2,000 watts (W) of electricity, depending on the model. hair dryers usually use between 15 and 20 amps and connect to a 120-volt outlet. How much you use your hair dryer has the biggest impact on how much electricity it uses over time.
Reasons for a GFCI Outlet to Trip When Nothing is Plugged in
This can happen if there is a fault in the wiring or if there is damage to the insulation on the wires. Ground faults can cause the GFCI outlet to trip even when there is no load on it.
Use a Testing Device
The only accurate way to test a GFCI outlet is with a test device that creates a ground fault. These testers simply need to be plugged into the outlet, then a test button on the device is pressed. If a problem is detected, the outlet will trip.
Average Cost
When you're looking into the cost to install a GFCI circuit breaker, you can expect to pay $228 - $313, typically, for materials and labor.
Typically, refrigerators should not be plugged into GFCI outlets. This is another appliance with a motor that can be prone to a little current leakage. Using a standard outlet saves nuisance tripping and the potential of waking up to a refrigerator full of warm food.
If the GFCI's internal current transformer senses more than a 4-5 milliamp loss, it instantly shuts down the outlet and any outlets it feeds to prevent accidental electrocution. Most often, when a GFCI “trips” it is the result of a faulty appliance plugged into the outlet or an outlet down circuit.
If your GFCI outlet keeps tripping with no load, there are several reasons why this might be happening. It could be a faulty outlet, an overloaded circuit, a ground fault in another outlet, water damage, or a faulty appliance.
