Normally, there is an overload fuse or breaker on the air handler / evaporator that protects the motor at more like 3 amps. This is supposed trip if the motor is overloaded. The 15 amp breaker is supposed to protect the conductors to the air handler / evaporator.

Why is my air conditioner tripping the circuit breaker?

Well, an air conditioner usually trips the breaker because it’s pulling in more amps than the breaker is rated for. That is, if you have a 20-amp breaker and the AC pulls 30 amps, the breaker trips. That’s why breakers trip: to protect you from over currents that can damage equipment and cause fires (yikes).

What causes a 15 amp breaker to trip?





If your circuit breaker keeps tripping, it’s usually a sign of something wrong with the circuit. There could be a short circuit in one of the appliances or somewhere in the wiring. There could be a ground fault causing the breaker to keep tripping. There could be a circuit overload.

What to do if AC keeps tripping?

Quote from the video:
Quote from Youtube video: It's a pretty good chance that's what it is what you could do is disconnect those same wires from the compressor. Then go reset your breaker.

Can you replace a 15 amp breaker with a 20 amp breaker?

If your wiring is of the correct gauge, you can change a 15-Amp circuit breaker to a 20-Amp breaker. A 15-Amp circuit uses a 14-gauge wire. A 20-Amp circuit breaker uses a 12-gauge wire. If the copper wire is 12 AWG, you can replace the 15A breaker with a 20A breaker.

Can a tripped breaker cause a fire?

Circuit breakers are designed to keep you and your family safe from fire, but one brand of breaker might not only fail to protect your family – it could actually cause a fire.

How many times can a breaker trip?





With 100 amp or less breakers they are tested to be operated 6000 times at rated current and 4000 without current, that is 10,000 operations, most likely they will never see that many operation unless the breaker is being used as a switch and in the right scenario, so highly unlikely this will be exceeded.

Should I worry if a breaker trips?

It can be a little unsettling when your circuit breaker trips. However, it is generally nothing to worry about. The primary reason for a circuit breaker to trip is having too many electric plugs into the same circuit. This is common in homes with older electrical work.

What are three warning signs of an overloaded electrical circuit?

Signs of Overloaded Circuits

  • Dimming lights, especially if lights dim when you turn on appliances or more lights.
  • Buzzing outlets or switches.
  • Outlet or switch covers that are warm to the touch.
  • Burning odors from outlets or switches.
  • Scorched plugs or outlets.

How much can you put on a 15 amp circuit?

As you add up the electrical loads, keep in mind that a wire rated at 15 amps can carry 15 amps all day long. However, 15-amp breakers and fuses can only carry 12 amps—80 percent of their rating—on a continuous basis. Continuous basis is considered to be a circuit loaded to capacity for three hours or more.

How much load can you put on a 20 amp breaker?



Allowable Breaker Load



The NEC does specify that a circuit breaker shouldn’t handle more than 80 percent of the load for which it is rated unless the breaker is labeled otherwise. By this standard, the total current draw on a 20-amp circuit shouldn’t exceed 16 amps.

How much does it cost to fix an overloaded circuit?

On top of regular wear and tear, overloaded circuits lead to a blown circuit breaker. This is an easy fix for a professional. So the cost comes in low at about $150. That includes materials and labor in most service calls.

Can you split a 15 amp breaker?

The circuit breaker amp size depends on the circuit you need to separate. I would usually recommend a 15-amp circuit breaker for lights and a 20-amp circuit breaker for outlets. These are the tools you need to split a circuit if you have a double-tapped breaker panel.

How much does it cost to replace a 20-amp breaker?



Cost to Replace Circuit Breaker Switch or Fuse



The cost to replace a circuit breaker switch or fuse is $100 to $250. Standard, 15- to 20-amp switches run $5 to $15 each. Standard, 15- to 20-amp fuses come in three packs for about $5 to $10.
