How do I stop my portable air conditioner from tripping the breaker?
The problem could be that the load of the AC combined with that of other appliances connected to the breaker exceeds the trip rating of the breaker.
1. Its own circuit breaker
When a CB gets old, it wears out, and eventually, it tends to cut off the power after a period of constant overheating.
2. Dirty AC components
Like any other appliance and electrical device, an air conditioner breaker keeps tripping if unwanted debris or dirt settles inside the AC components. You will notice a rise or unpleasant change in temperature despite using an AC.
3. Short circuit
A short circuit is a common wiring problem that results in a tripping breaker. This happens when two normally-sheathed wires (e.g., hot or neutral wires) touch each other. The electric current will then travel into a low-resistance path, causing the breaker to cut off the power.
5. Your AC system is frozen
A frozen AC is undoubtedly a pain in the ass. This happens when your room or building has a higher temperature than usual, the AC filter is wet, the evaporator coil is covered in ice, and the supply registers don’t release warm air, often because you have neglected maintenance.
6. Refrigerant issues
Refrigerants are supposed to help your AC eradicate the warm air inside your house by circulating the heat from your indoor unit towards the outside unit. So, if you have a leak somewhere in your AC, expect that your refrigerant level will drop.
Why does my portable AC keep tripping the breaker?

What is a circuit breaker?
Circuit breakers are designed to protect the electrical systems in your home (and the devices that are plugged into them) by cutting off the electrical supply when a device attempts to pull more amps than the breaker is rated for. For example, let’s say you have a 20-amp breaker and a 30-amp AC.
What happens if you don't pull a 30 amp breaker?
If it didn’t do that, there’s a considerable chance that both the AC and the electrical outlet would fry and possibly even catch on fire.
Is the capacitor in my AC faulty?
The capacitor is faulty. This will also need to be handled professionally. The condenser coils are dirty. You can try to clean the coils on your own, but it’s probably safer to have it done by an expert. The AC is running low on refrigerant.
Why does my AC circuit breaker trip?
Another reason for a circuit breaker to trip is because of an electrical short. When two normally sheathed wires like a hot wire and a neutral wire touch each other when voltage is applied, it causes a major event. The AC uses 240 volts. This means the two or three wires leading to your motor carry at least 120 volts.

Here are some reasons your AC will cause circuit breaker tripping: The breaker could be bad. The compressor or fan is drawing too many amps. A short circuit.
What causes a breaker to trip?
A breaker trips when there is too much power consumption or current at any given time. The wire from the AC to the panel heats up enough that it trips. This stops a potentially hazardous situation from happening. Here are some reasons your AC will cause circuit breaker tripping: 1 The breaker could be bad 2 The compressor or fan is drawing too many amps 3 A short circuit 4 Refrigerant pressure issues
Why does my AC compressor trip?
One last reason a compressor could trip the AC breaker is refrigerant pressure. If the pressure is too high in the system, meaning there is too much refrigerant, the compressor is once again having to strain too hard to do its work. The breaker won’t trip immediately, but over time.
How does a hard start capacitor work?
Assuming the capacitor is good, sometimes adding a hard-start capacitor to the circuit will help give it that boost needed to turn the motor over .
What happens when two wires touch each other?
If two bare wires touch each other when the system is supposed to be on, a high current situation can occur, causing the breaker to trip. As soon as the voltage is applied, the breaker will trip immediately.
What happens if a motor gets stuck?
If a motor gets stuck and can’t turn over when the proper voltage is applied, the motor will pull a higher number of amps. So much so that the heat builds up in the wiring and trips the breaker. This won’t trip the breaker immediately.
What happens if the AC doesn't trip the breaker?
If the AC doesn’t cause the breaker (of the same trip rating) on another circuit to trip, and it’s the only load on the circuit, then it’s probably the breaker. If the AC trips the breaker no matter what circuit you plug it into, then it’s probably the AC unit.
Why does my refrigerator compressor kick on?
First, if the refrigerator circuit is shared with other outlets or equipment, when that other equipment is running or outlet is being used, and the refrigerator compressor kicks on, it is too many amps for the breaker and it trips. Second, the breaker may be the wrong type or undersized.
What does it mean when a blower is grounded?
A "grounded blower" or "blower short to ground" implies that an electrical twisting inside the blower has broken and hit the side of the blower. This makes an immediate short ground, lighting the oil and causing a burnout. Also, obviously, the electrical switch trips because of the unexpected flow flood.
What does a grimy channel do to an AC blower?
